Embodiments for Carrying Out the Invention Next, embodiments of the present invention will be described with reference to the drawings. In the description of the following drawings, the same or similar symbols will be attached to the same or similar parts.

(Embodiment) The pant 1 according to the embodiment of the present invention is a close-fitting garment that is directly worn on the wearer's skin, covers the lower abdomen, and has a bottom portion. The panties 1 prevent the hem of the panties from being shifted upward with the movement of the legs or the extension and the like, and are caught by the hip joints.

As shown in FIGS. 1 and 2, the pants 1 includes a back body portion 2, a front body portion 3, and a bottom portion 4. The back body portion 2 covers the back side of the wearer. The front body portion 3 covers the ventral side of the wearer. The bottom portion 4 is covered with a bottom sill (underarm).

By connecting the end portions of the rear body portion 2 and the front body portion 3 in the horizontal direction, and connecting the lower end of the rear body portion 2 and the rear end of the bottom portion 4, and connecting the lower end and the bottom of the front body portion 3 The front end of the portion 4 can be formed into a cylindrical shape covering the lower abdomen. A through-hole 11 is formed in the circumferential direction of the upper end of the back body part 2 and the front body part 3. Left and right leg circumferences 12 are formed in the lower end of the back body part 2 and the front piece part 3, and the part which is not connected to the bottom part 4 is formed. The wearer can wear the panties 1 by the legs through the left and right leg circumferences 12 formed under the panties 1. A stretchable webbing is disposed at the entrance 11 and the leg circumference 12, and is formed to conform to the body and legs of the wearer.

The back body portion 2 includes a left back body portion 21 that covers the left side of the back surface, and a right back body portion 22 that covers the right side of the back of the wearer. The left back body portion 21 and the right back body portion 22 are connected by the difficult-to-stretch portion 23. The difficult-to-stretch portion 23 is formed to be more difficult to stretch than the back body portion 2 in the lower portion of the center after the back body portion 2. In the embodiment of the present invention, the difficult-to-stretch portion 23 is a seam where the left back body portion 21 and the right back body portion 22 are sewn. In the embodiment of the present invention, in the suspending portion, each of the fabrics forming the left back body portion 21 and the right back body portion 22 is sewn by a thread, so that the difficult-to-stretch portion 23 is formed to be more flexible than the back body. The fabric of the sheet portion 2 is lower and becomes difficult to stretch.

The back body piece portion 2 and the front body piece portion 3 according to the embodiment of the present invention may also be made of an elastic fiber woven fabric, an elastic knitted fabric, a woven fabric, a velvet knitted fabric, or a tricot. It may be formed by a knitted fabric such as Double-Raschel, or may be formed of a woven fabric made of a stretchable wire, or may be formed of a non-fiber stretchable material such as rubber or polyurethane.

Preferably, the back body portion 2 and the front body portion 3 have a stretch ratio of about 90% to 160% in the vertical direction and a stretch ratio of about 140% to 220% in the left and right direction. Preferably, the back body portion 2 and the front body portion 3 are materials having a pressure of 15 cN to 35 cN in the vertical direction and a pressure of 15 cN to 35 cN in the left and right direction.

The panties 1 according to the embodiment of the present invention are capable of extending the hem to keep the skin moving even when exercising, and can cover the buttocks of the wearer in a wide range. When the elongation in the up-and-down direction is lower than 90%, there is a possibility that the yaw is likely to be displaced. When it is larger than 160%, the hem is excessively pulled up while wearing. The position of the offset is the case. When the stretching ratio in the left-right direction is lower than 140%, there is a case where the hem can be prevented from catching up and the yaw is likely to be displaced. When the ratio is larger than 220%, the cloth is easily stretched. Let the panties 1 be caught in the hip joint. Further, it is preferable to use a material having the same pressing force in both the up and down direction and the left and right direction.

In the embodiment of the present invention, the test piece of 160 mm × 25 mm is attached to a constant-speed elongation type tensile tester by sandwiching 25 mm of the upper part, 35 mm of the lower part, and a gap of 100 mm, and the elongation and elongation are measured. Force and tight pressure. The plurality of test pieces used were cut into pieces in such a manner that the warp direction and the weft direction of the cloth were in the longitudinal direction (16 mm side).

The elongation was a value obtained by attaching a test piece to a constant-speed elongation type tensile tester and applying a load of 9.8 N to each of the test piece in the left-right direction and the up-and-down direction. The pressing force is to mount the test piece on a constant-speed elongation type tensile tester, and repeat the plurality of elongation recovery at a speed of about 300 mm/min, and return to the force at 30%.

The bottom crotch portion 4 is the bottom of the wearer, more specifically, the dirt from the urethral portion and the vaginal opening, and is formed to be more difficult to stretch than the posterior body portion 2. By forming the bottom portion 4 so as to be difficult to expand and contract, the position of the pants 1 can be made difficult to shift and comfortable to wear.

In the embodiment of the present invention, the bottom portion 4 is formed to be more difficult to stretch than the back body portion 2 by stacking the fabric forming the back body portion 2 and the front body portion 3 into two layers. It is not limited to this. For example, the bottom portion 4 may be used by stacking any of the fabrics into three or more layers, or a fabric that is more difficult to stretch than the front body portion 3 and the back body portion 2 may be used as one layer. Further, the bottom portion 4 can be formed by further superposing another fabric on the cloth forming the back body portion 2 and the front body portion 3.

It is preferable that the bottom sill portion 4 has an elongation ratio in the vertical direction of about 20% to 50%, and an elongation ratio in the left-right direction of about 80% to 130%. Further, when the elongation in the lower direction of the bottom portion 4 is too large, the bottom portion 4 is caught in the underarm due to the excessive stretching of the cloth, or the lower end position of the difficult-to-expand portion 23 to be described later is shifted. Case. In addition, when the stretch ratio in the lower direction or the left-right direction of the bottom portion 4 is too small, the adhesion to the body may be deteriorated or the touch of the skin may be deteriorated.

In the embodiment of the present invention, as shown in FIG. 2, the upper body portion 2 is extended to the front side, and the rear body portion 2 and the front body portion 3 are connected to the lower abdomen side of the wearer. However, it is not limited to this. The back body portion 2 and the front body portion 3 may be connected to the left and right ends (side ends) of the wearer. Further, in the embodiment of the present invention, the case where the front body portion 3 and the bottom portion 4 are separately formed will be described, but it may be integrally formed.

(Connection of the rear body portion to the bottom portion) In the pants 1 according to the embodiment of the present invention, the back body portion 2 and the bottom portion 4 are formed to be connected to the front side in comparison with the general pants. In the general panties, the back body portion 2 and the bottom crotch portion 4 are connected behind the anus K, and the bottom crotch portion 4 of the embodiment of the present invention is as shown in FIG. The position of the anus K is connected to the back body portion 2 more forward.

The rear end 41 of the bottom crotch portion 4 is disposed near the perineum. The bottom portion 4 is the bottom of the wearer, and more specifically, the bottom end 41 of the bottom portion 4 is disposed at least rearward than the position of the vaginal opening, since the dirt from the urethral portion and the vaginal opening is received. More forward than the position of the anus K.

As shown in Fig. 2, the rear end 41 of the bottom portion 4 can be confirmed in a flat state in which the front piece 3 is placed upward. Further, in FIG. 2, the connection portion between the hard-to-expandable portion 23 and the rear end portion 41 of the bottom portion 4 and the front piece portion 3 can be confirmed together, wherein the difficult-to-stretch portion 23 is connected to the left rear body portion 21 and Right rear body portion 22. On the other hand, as shown in FIG. 1, when the wearing state of the pants 1 is viewed from the back side, the rear end 41 of the crotch portion 4 cannot be confirmed above (back) than the anus K, but as shown in FIG. As shown in the figure, when viewed from the obliquely downward direction, the rear end 41 of the crotch portion 4 can be confirmed. Further, as shown in FIG. 4, the rear end 41 of the bottom sill portion 4 cannot be confirmed in a flat state in which the back body portion 2 is placed upward.

The state in which the pant 1 according to the embodiment of the present invention is worn and the state in which the general pant is worn is referred to with reference to Fig. 5 (a) and the state in which the pant 1 of the embodiment of the present invention is worn is described from the side.

In Figure 5, the left side is the front of the wearer and the right side is the back of the wearer. The solid line having a semicircular shape of Fig. 5 is the outline of the wearer's left and right center lines, and passes through the hip joint in the back side. The solid lines shown below and to the right outside the semicircular shape are the outlines when the wearer is viewed from the left side, and the outlines of the legs to the buttocks are displayed. Further, the one-point chain line indicates the height T of the buttocks tip end, and more specifically, an imaginary water level indicating the height of the position of the top of the buttocks. In the embodiment of the present invention, the top of the buttocks is the most convex position of the buttocks in the front-rear direction.

As shown in Fig. 5(a), the rear end 41 of the crotch portion 4 of the panty 1 is disposed forward of the position of the anus K, and the rear body portion 2 is formed near the position of the anus K. On the other hand, as shown in FIG. 5(b), the rear end 410 of the bottom portion 40 of the general panties is disposed rearward of the position of the anus K, and the bottom portion 40 is provided near the position of the anus K.

According to the knowledge of the inventors, since the movement of the leg such as the leg movement is an activity for moving the hip joint, the muscle on the hip joint generates an activity by the movement of the leg. Further, since the hip joint is closely arranged with the anus K, the muscles near the anus K generate activity by the movement of the legs, and the skin near the anus K is easily moved. As shown in FIG. 5(b), when the bottom crotch portion 40 is provided in the vicinity of the anus K, since the bottom crotch portion 40 is formed to be difficult to expand and contract, the bottom crotch portion 40 cannot keep up with the movement of the leg. The skin's activity stays in place, and it is easy to produce a shift in the hem.

In the pants 1 according to the embodiment of the present invention, as shown in FIG. 5(a), the rear end 41 of the bottom portion 4 is disposed forward of the position of the anus K, and the bottom portion 4 is disposed near the anus K. The back body part 2 that is more easily retractable. Thereby, even if the movement of the muscles near the anus K is generated by the movement of the legs, the easily stretchable rear body portion 2 can keep up with the movement of the muscles, and the shift of the hem can be avoided.

Further, since the rear end 41 of the sill portion 4 is disposed even when the leg moves, the activity of the skin is still small. Therefore, even if the bottom sill portion 4 is formed to be difficult to expand and contract, the hem does not occur. Offset.

Referring to Fig. 6, the connection position between the back body portion 2 and the bottom portion 4 will be described from a different viewpoint. Fig. 6(a) shows a state in which the panties 1 of the embodiment of the present invention are stacked sideways so that the left and right leg circumferences 12 are overlapped and laid flat so that the waist line is not inclined forward and backward, and Fig. 6(b) is The general panties are placed in the same state as in Fig. 6(a). The left side of Figure 6 is the front side of the wearer and the right side is the back side.

In Fig. 6(a), the position P11 is the rear end 41 of the bottom portion 4. The position P12 is the lowest point of the leg circumference 12 when the panties 1 are laid flat as shown in FIG. 2 so that the front and back sides of the pants 1 overlap. When the pants 1 according to the embodiment of the present invention are placed as shown in Fig. 6(a), the position P11 of the rear end 41 of the bottom crotch portion 4 is provided forward of the position corresponding to the anus K of the panties 1. Further, the position P12 of the lowest point of the leg circumference 12 is provided at a position rearward from the same position as the rear end 41 of the bottom portion 4.

On the other hand, a case where the general panties are placed in the same manner as in Fig. 6(a) will be described. In FIG. 6(b), the position P16 is the position P11 corresponding to FIG. 6(a) and is the rear end 410 of the bottom portion 40. The position P17 corresponds to the position P12 of Fig. 6(a), and is the lowest point of the leg circumference when the general panties are laid flat as shown in Fig. 2 so that the front and back sides of the panties overlap. When the general panties are placed as shown in Fig. 6(b), the position P16 of the rear end 41 of the bottom crotch portion 4 is disposed rearward of the position of the panty 1 corresponding to the anus K. Further, the position P17 of the lowest point of the leg circumference is disposed forward of the rear end 410 of the bottom portion 40.

As described above, in the pants 1 according to the embodiment of the present invention, the rear end 41 of the bottom portion 4 is disposed forward of the anus K. Further, in a state in which the pants 1 are stacked sideways so that the left and right leg circumferences 12 are overlapped and laid flat so that the waist line is not inclined forward and backward, the position P11 of the rear end 41 of the bottom crotch portion 4 is disposed in the leg portion. The lowest point P12 of the circumference is more forward or at the same position. Thereby, the back body piece 2 which is more easily expanded and contracted than the bottom crotch portion 4 can be disposed at a position near the anus K. By stretching the movement of the leg and the muscles of the buttocks near the anus K, the skin is stretched, and the cloth near the anus K of the panties 1 is stretched to keep up with the movement of the skin, so the panties 1 can be prevented. The upward movement of the pendulum is accompanied by the activity of the leg.

(Difficult-Retractable Portion) The difficult-to-stretch portion 23 according to the embodiment of the present invention is disposed on the right and left center lines from the rear end 41 of the bottom portion 4 to the upper end of the back body portion 2. The difficult-to-contract portion 23 is a seam line of the left back body portion 21 and the right back body portion 22. Since the difficult-to-stretch portion 23 is formed so as to be difficult to move and adhere to the skin, it is responsible for avoiding the yaw offset.

The difficult-to-stretch portion 23 is disposed from the rear end 41 of the bottom portion 4, and the bottom portion 4 is a portion where the activity of the skin of the leg is small. Therefore, the connection portion between the difficult-to-stretch portion 23 and the bottom portion 4 is difficult to move even when the wearer moves, and the lower end portion of the difficult-to-expand portion 23 can be stably disposed on the wearer's skin.

For example, as shown in FIG. 5(b), the rear end 410 of the conventional sill portion 40 is formed rearward than the anus K. Since the wearer is viewed from the side, the seam line 230 of the left back body portion and the right back body portion is from the rear end 410 of the bottom crotch portion 40 to the buttock tip height T, and is in the almost vertical direction. Since the skin of the wearer is arranged almost in parallel, the conventional seam line 230 is difficult to adhere to the skin and has a low degree of adhesion to the skin. Further, in the conventional pants, since the rear end 410 of the bottom portion 40 is located rearward of the rear end 410 of the bottom portion 4 of the embodiment of the present invention, the seam line is accompanied by the wearer's activity. The lower end of the 230 is easily offset to the left and right, and the seam line 230 is easily displaced.

On the other hand, in the hard-to-expandable portion 23 according to the embodiment of the present invention, as shown in FIG. 5(a), the bottom portion of the body where the rear end 41 of the bottom portion 4 is located is used as a starting point, and FIG. 5(b) is drawn. Compared to larger curves and along the hip seam. As a result, when the wearer is viewed from the left side, the difficult-to-stretch portion 23 is placed on the wearer's skin in a stable manner by applying a force Pw1 to the skin from the rear end 41 of the bottom portion 4 to the buttock height T. It can be understood that the force Pw1 applied to the skin by the difficult-to-stretch portion 23 is larger than the force Pw10 applied to the skin by the conventional seam line 230, and the difficult-to-expand portion 23 is formed to be further more compact than the conventional pant. On the skin.

As described above, the hard-to-expandable portion 23 of the embodiment of the present invention is formed to be more difficult to expand and contract than the cloth of the left rear body portion 21 and the right rear body portion 22, starting from the front of the anus K. It is attached to the skin. Therefore, even if the movement of one of the legs causes the hem of the back body to be active, the influence of the activity of the hem described above does not propagate to the hem of the inactive leg, and the inactive one can be avoided. The situation where only the hem of the leg is messed up.

For example, the skin on the left side of the buttocks is moved by the movement of the left leg, and the deviation of the cloth is enlarged along with the movement of the skin below the left back body portion 21. However, since the difficult-to-stretch portion 23 is stably disposed on the skin and is difficult to expand and contract, the offset of the cloth generated under the left back body portion 21 is blocked, and it is difficult to be below the right back body portion 22. Produces the offset of the cloth.

In the embodiment of the present invention, the back body piece 2 is formed by sewing the respective fabrics of the left back body portion 21 and the right back body portion 22 with the difficult-to-expandable portion 23, but the invention is not limited. herein. For example, the back body piece 2 may be formed by attaching a web that can restrict the expansion and contraction to the cloth in which the back body piece is integrally formed. In addition, it is also possible to form the back body piece 2 by changing the knitting method so that the position of the hard-to-expandable portion 23 of the fabric of the back body piece is not easily stretched and the other is easy to expand and contract at a position other than the stretched portion 23 of the back body piece. .

As described above, the pants 1 according to the embodiment of the present invention are provided with the rear end portion 41 of the bottom crotch portion 4 of the back body portion 2, and have the difficult-to-expand portion 23 on the right and left center lines, and the hard-to-expand portion 23 is smaller than the rear body portion. 2 is more difficult to stretch. Since the hard-to-contract portion 23 is disposed along the hip joint, the movement of the hem of one of the legs is not transmitted to the hem of the other leg, and the prevention can be prevented. In the pants 1, by performing the activities of the independent lower pendulum in the left and right hem, the yaw offset can be prevented from being enlarged, which contributes to the elimination of the yaw offset.

(The remaining amount securing portion) As shown in FIG. 4, in the back body portion 2 of the pants 1 according to the embodiment of the present invention, the remaining amount securing portion 24 is formed in a portion above the center in the left-right direction of the back body portion 2, The remaining amount securing portion 24 ensures a margin in the left-right direction as compared with the left and right upper portions. The remaining amount securing portion 24 is formed in the penetrating opening 11 by creping the upper end of the rear body piece 2 with a crease.

According to the knowledge of the inventors, it is known that the shift of the hem of the panties is mostly observed in the teens (especially 13-18 years old) before becoming the body shape of an adult woman. This age girl has a tendency to bulge compared to adult female pelvis, and the upper part of the gluteus maximus (the gluteus maximus above the top of the buttocks) tends to bulge. When the girl with the bulge in the upper part of the gluteus maximus is pulled up in the general panties, in order to cover the protrusion on the upper part of the gluteus maximus, the back piece of the panties will extend in the up and down direction, and there is The fabric under the panties becomes insufficient or the amount of stretch of the fabric cannot be ensured. If the fabric is not enough under the panties, or if the fabric is not stretched, the leg movement will be carried out. Because there is no cloth reserve, the fabric cannot keep up with the skin of the buttocks, making it short. The hem of the underpants is caught, causing a shift in the hem.

Therefore, in the pants 1 according to the embodiment of the present invention, the remaining amount is ensured by the remaining amount securing portion 24 in the upper portion of the center portion of the back body portion 2 in the left-right direction, thereby securing the raised fabric covering the upper portion of the gluteus maximus. The fabric and the amount of stretch under the back body portion 2 are eliminated. Further, since the amount of stretch of the cloth or the cloth that can keep up with the movement of the skin of the buttocks can be ensured under the back body portion 2, it is possible to avoid the sag of the panties or the shift of the hem.

In addition, in the above description, the example of the teenage girl who is the body type of the adult female is exemplified, but the remaining amount securing portion 24 of the embodiment of the present invention is not limited to the age, the sex, and the upper part of the buttocks. A wearer with a weight is effective.

The remaining amount securing portion 24 is provided at a position corresponding to the convex portion of the upper portion of the buttocks, more specifically, in the non-wearing state, in the left-right direction, having about 1/3 of the left-right direction of the back body piece portion 2 The length of 3/4 has a length of about 1/3 to 2/3 of the length of the upper body portion 2 in the upper and lower directions. In the "non-wearing state" of the embodiment of the present invention, when the back body portion 2 is not stretched by wearing or the like, the upper end and the lower end of the rear body portion 2 can be confirmed on a predetermined base. status.

As shown in FIG. 4, when the left and right widths of the flat state of the pants 1 are L, the length L1 of the remaining amount securing portion 24 in the left-right direction is 1/3 to 3/ of L. 4 or so. In addition, when the vertical width of the rear body portion 2 is H (not shown), the length H1 of the remaining amount securing portion 24 in the vertical direction is about 1/3 to 2/3 of H.

When the remaining amount securing portion 24 is narrower than the above range, there is a case where the projection on the upper portion of the buttocks cannot be sufficiently matched. Further, when the remaining amount securing portion 24 is wider than the above range, the remaining amount of the cloth may be generated and the distortion or the offset may occur.

Here, the remaining amount securing portion 24 is provided near the left and right centers of the pants 1 and is not provided on the side edges. Thereby, the side of the panties 1 can be applied to the wearer's skin to prevent the panties 1 from being displaced in the circumferential direction.

The shape in which the left back body portion 21 is laid flat will be described with reference to the paper type of the left back body portion 21 of Fig. 7 . In addition, the figure shown in FIG. 7 is deformed for the sake of explanation, and the shape of the left back body portion 21 is not necessarily the same as that of FIG.

In FIG. 7, the positions P21, P22, and P23 are formed to be respectively located on the right and left center lines of the wearer wearing the pants 1. The position P21 corresponds to the intersection of the rear end 41 of the bottom portion 4 and the left and right center lines. The position P22 corresponds to the intersection of the upper end of the back body portion 2 and the left and right center lines. The position P23 corresponds to the intersection of the horizontal plane passing through the height of the top of the buttocks and the left and right centerlines.

As shown in FIGS. 7(a) and 7(b), portions P21 to P23 are formed linearly, and portions of the hard-to-stretch portion 23 are formed on the right and left center lines. The positions P23 to P22 are formed by bending toward the side sides. By sewing the left back body portion 21 and the right back body portion 22 which is formed symmetrically and similarly to the left and right, a swollen portion having a vertex at the position P23 is formed, and the buttocks can be covered.

As shown in FIG. 7(b), in the vicinity of the left and right center lines of the left back body portion 21, the positions P21 to P23 are linearly formed, and the positions P23 to P22 are not straight lines but are formed to be drawn to the right side. The curve that bulges (in the direction of the left side). In this way, by forming the left back body portion 21 so as to draw a bulging curve above the butt tip height position P23, it is possible to secure a sufficient amount of cloth for forming wrinkles in the remaining amount securing portion 24 ( The hatched portion of Figure 7(b)).

In addition, the method of securing the margin of the fabric for forming the wrinkles in the remaining amount securing portion 24 described with reference to FIG. 7(b) is an example, and other methods may be considered.

As described above, in the pants 1 according to the embodiment of the present invention, the remaining amount securing portion 24 is formed in the vicinity of the left and right center lines of the back body portion 2 and above the height position of the buttocks. When a raised wearer wears a general brief on the buttocks, the back of the shorts covers the protrusions above the buttocks, resulting in insufficient fabric of the hem of the briefs and contributing to the upward deflection of the hem. On the other hand, since the pants 1 according to the embodiment of the present invention can cover the projections on the upper side of the buttocks by the remaining amount securing portion 24, it is possible to prevent the fabric of the hem of the back body portion 2 of the pants 1 from being insufficient.

(Evaluation) The effect of wearing the pants 1 according to the embodiment of the present invention will be described with reference to Figs. 8 to 10 .

Fig. 8 is a view showing a state in which the panties 1 according to the embodiment of the present invention and the conventional panties are respectively worn, and a state in which a predetermined exercise is performed after wearing the panties. Fig. 8 (a) shows a state in which the panties 1 according to the embodiment of the present invention are worn, and Fig. 8 (b) shows a state in which the panties 1 are worn and a predetermined movement is performed. Fig. 8(c) shows a state in which the general panties 1 are worn, and Fig. 8(d) shows a state in which the general short pants are worn after performing the same predetermined movement as in Fig. 8(b). Here, the prescribed exercise is a two-folded flexion and extension exercise and four leg-lifting exercises.

Compared to Fig. 8(a), Fig. 8(b) shows a slight shift in the hem of the left side of the back body portion 2. However, compared to Fig. 8(a), in Fig. 8(b), there is no significant wrinkle in the hem near the left and right centerlines, and the panties 1 cover the gluteal groove, while remaining as shown in Fig. 8(a) The same wearing state before the exercise.

On the other hand, compared with FIG. 8(c), FIG. 8(d) shows that the offset is observed in the hem of the left and right side sides of the back body piece 2. Further, compared with FIG. 8(c), wrinkles are generated at the hem of the left and right center lines of FIG. 8(d), and the panties 1 are not displaced upward by the panties, so that the pants 1 cannot cover the gluteal groove and expose the gluteal groove.

As shown in Fig. 8(b), after the movement of the pants 1 according to the embodiment of the present invention, the same wearing state as before the movement is maintained, whereas, as shown in Fig. 8(d), the wearing is performed. After the exercise of the short panties, the dress has been greatly distorted. From this point of view, it is understood that the panties 1 of the embodiment of the present invention can eliminate the offset of the hem of the panties.

Moreover, the wearer of the panties 1 according to the embodiment of the present invention has received the following praises: "I won't get stuck in the buttocks", "When I put on, I will stretch and surely wear it", "The bottom of the buttocks fits snugly." a feeling of". On the other hand, we also get the following comments from the wearer of the general briefs: "The hem is shifted and will be noticed", "The cloth is caught, and it enters the ass."

Referring to Fig. 9, an experiment for measuring the position of the hem before and after the exercise will be described with respect to the pants 1 and the general panties according to the embodiment of the present invention. Figs. 9(a) and 9(b) are views showing the standing state and the movement of the pants 1 according to the embodiment of the present invention, and Figs. 9(c) and (d) are the standing state in which the general panties are worn and Figure during exercise. 9(a) and 9(c) are views showing the standing state from the back side, and the motions in Figs. 9(b) and (d) are bending motions. Fig. 9 (b) and (d) are views for observing the buttocks in a curved state from the obliquely downward direction.

In the experiment shown in Fig. 9, the distance from the position of the anus K to the position P of the intersection of the rear end and the leg circumference of the bottom of the general panties and the position P' on the wearer's skin were measured. 1 distance. In Figs. 9(a) and (c), before the exercise, the position P of the intersection of the rear end of the bottom of the general panties and the leg circumference is the same as the position P' of the wearer's skin of the position P. of. Furthermore, the position P (position P') of Fig. 9(a) is the intersection of the rear end of the bottom of the general panties and the leg circumference, and the intersection of the rear end of the bottom portion of the panties 1 and the leg circumference. Inconsistent.

When the standing state of Figs. 9(a) and (c) is formed into a curved state, the skin of the buttocks is stretched, and the position P is deviated from the position P' (the position on the skin at the position P when standing). However, in Fig. 9(b) in which the pants 1 of the embodiment of the present invention are worn, the distance between the position P and the position P' is shorter than that of Fig. 9(d) in which the general panties are worn. It can be seen that in the panties 1, the fabric has been accompanied by the skin of the buttocks.

The experimental results of Fig. 9 will be described with reference to Fig. 10 . Fig. 10(a) shows the results of experiments in which a number of M sizes were worn, and Fig. 10(b) shows the results of experiments in which a number of L sizes were worn. In each of the graphs of Figs. 10(a) and (b), the upper part shows the experimental result of the pant 1 wearing the embodiment of the present invention, and the lower part shows the result of the experiment wearing the conventional panty. The white background portion in the graph of Fig. 10 is the distance from the anus K to the position P (position P') in the standing state, and the sparse hatched portion is the difference between the movement from the anus K to the position P and the standing time. The thicker hatched portion is the distance from the position P to the position P' during the movement.

Fig. 10 (a) and (b) are the difference between the movement from the anus K to the position P and the standing position (the sparsely hatched portion), compared to the case where the conventional panties are worn. In the case of the pants 1 according to the embodiment of the present invention, it becomes long. Thereby, it can be confirmed that the hem of the panties 1 is also stretched in conjunction with the stretching of the skin accompanying the bending motion.

Further, it can be seen that the distance from the position P to the position P' during exercise (the thicker hatched portion) is shortened when the pant 1 of the embodiment of the present invention is worn, and can be reduced. The amount of fabric that is insufficient when bent. From Fig. 10, it can be confirmed that the pant 1 of the embodiment of the present invention stretches to keep up with the activity of the skin even when exercising, and covers the buttocks of the wearer in a wide range.

(Modification of the difficult-to-expandable portion) In the pants 1 according to the embodiment of the present invention, the difficult-to-stretch portion 23 is extended from the center of the rear end 41 of the bottom portion 4 to the left-hand center line to the back body portion 2 The situation up to the top, but not limited to this. In the pants 1 according to the embodiment of the present invention, the difficult-to-stretch portion 23 is formed by the sewn portions of the respective cloths of the left back body portion 21 and the right back body portion 22, but Not limited to this.
