Description

  The present invention relates to a fishing rod provided with a hollow rod body in which a rear grip portion is integrally formed.

  When the fishing rod is provided with a rear grip, a cylindrical rear grip body is formed from cork or foamed resin, and it is attached to the rear outer peripheral surface of the rod body (blank), so that the rear grip is removed from the cylindrical rear grip body. Often comprises a part. However, if the rear grip portion is configured separately from the rod body, it is difficult to reduce the weight, and the sensitivity transmitted from the fishing rod to the hand also decreases.

  In contrast, the present applicant has already proposed a configuration in which the rear grip portion is integrally formed by increasing the diameter of the rear portion of the hollow rear grip housing (see Patent Document 1 below). Thus, weight reduction and high sensitivity can be achieved by forming the rear grip part integrally with the bag main body.

  By the way, the rear grip portion is gripped by a hand opposite to the hand gripping the reel sheet at the time of casting, for example. For example, when a fishing rod is gripped with the right hand, the rear grip portion can be gripped with the left hand to perform so-called double hand casting. Since the rear grip portion has a shape bulging outward in the radial direction, the rear grip portion can be firmly held and cast.

  In order to secure a sufficient holding feeling and gripping force when gripping the rear grip part, it is necessary to increase the diameter of the rear grip part to some extent. On the other hand, there is a strong demand to make fishing rods as light as possible. The rear grip portion has an integrated configuration and is significantly lighter than a separate configuration, but further weight reduction is also required.

Japanese Patent No. 5721574

  An object of the present invention is to further reduce the weight of a fishing rod provided with an integrated rear grip portion while ensuring a hold feeling and grip force of the rear grip portion.

  The present invention has been made to solve the above problems, and a fishing rod according to the present invention includes a rod body in which a hollow rear grip portion is integrally bulged radially outward, and a reel seat. The rear grip portion is offset downward with respect to the center of the rod body. Note that the upper and lower directions are based on a normal use state in which the reel is mounted on the reel sheet. Usually, the spinning reel is located on the lower side of the fishing rod, and the two-axis reels are located on the upper side of the fishing rod.

  When fishing with a reel mounted on the fishing rod having the above configuration, for example, a double-hand cast can be performed by holding the reel seat with the right hand as one hand and the rear grip with the left hand as the other hand. it can. When gripping the rear grip portion, the rear grip portion is gripped from below. And since the rear grip part is offset and formed in the lower side, the amount of bulging to the lower side in the rear grip part is secured, and it is easy to grip. On the other hand, the amount of bulging upward in the rear grip portion is small, and the volume of the rear grip portion as a whole is small relative to the amount of bulging downward.

  In particular, it is preferable that the cross-sectional shape of the rear grip portion is a left-right symmetric non-circular shape and that the curvature radius of the upper surface is larger than the radius of the circumscribed circle. According to such a structure, the upper surface of a rear grip part turns into a curved surface close | similar to a plane. For example, when catching a fish or interacting with a hung fish, the fishing rod can be supported by placing the forearm or elbow of the hand holding the reel seat against the upper surface of the rear grip portion. Thus, by applying an elbow or the like to the upper surface of the rear grip portion, the fishing rod can be firmly fixed between the hand holding the reel seat and the elbow or the like. Therefore, the fishing rod becomes stable when hooking the fish or interacting with the fish that has been hung. In addition, by applying an elbow or the like to the rear grip portion, vibration that conveys the state of fish when it hits the seabed or rocks is transmitted from the rear grip portion. As described above, if the upper surface of the rear grip part is a curved surface close to a flat surface, the area to which the elbow etc. is applied will be widened, and it will be easier to apply the elbow etc. to the upper surface of the rear grip part. The stability can be improved, and vibrations such as claws can be easily transmitted to the elbows. In addition, the curvature radius of the upper surface may be a curvature radius in the vicinity of the uppermost portion in the cross-sectional shape.

  Furthermore, it is preferable that the cross-sectional shape of the rear grip portion is a shape that becomes narrower toward the lower side in the region on the rear side of the inflection point on the lower surface of the rear grip portion. The tip side is the front side and the buttock side is the rear side. The lower surface of the rear grip portion is curved upwardly along the front-rear direction before the inflection point, and is curved downwardly along the front-rear direction after the inflection point. And in the area behind the inflection point of the lower surface, if the cross-sectional shape of the rear grip portion becomes narrower toward the lower side, the entire bulge is ensured while ensuring the downward bulge amount. Volume can be suppressed and weight can be reduced. In this way, the shape narrowed toward the lower side includes, for example, a substantially inverted triangular shape, a substantially inverted trapezoidal shape, a substantially inverted pentagonal shape, etc. The upper surface of the rear grip portion can be formed in a curved shape close to a flat surface while suppressing the volume.

  In addition, in the region on the rear side of the inflection point on the lower surface of the rear grip portion, it is preferable that the radius of curvature of the lower surface of the rear grip portion gradually increases toward the rear side. When grasping the rear grip part, grasp it lightly with the index finger or middle finger, and firmly grasp it with the ring finger or little finger. Therefore, by making the curvature radius of the lower surface of the rear part where the ring finger or little finger hits into a rounded shape, it can be firmly gripped, and the uncomfortable feeling when gripping is also reduced. Also, by reducing the radius of curvature of the lower surface of the front part where the index finger or middle finger hits, the lower surface becomes a circumferential hook when the index finger or the middle finger is applied, and the hand moves in the circumferential direction against the rear grip part. It becomes hard to slip. In addition, the curvature radius of a lower surface is good also as a curvature radius of the lowermost part vicinity in cross-sectional shape.

  Moreover, it is preferable that the corner | angular part is formed in the inflection point of the lower surface of a rear grip part. Since the corner portion is a portion where the curvature radius in the front-rear direction is locally reduced, the rear grip portion can be gripped by hooking, for example, an index finger on the front side of the corner portion. By hooking a finger on the corner in this way, the hand is less likely to slip in the front-rear direction.

  The fishing rod according to the present invention is a fishing rod provided with a rod body in which a hollow rear grip portion is integrally bulged radially outward, and the rear grip portion is offset with respect to the center of the rod body. It is characterized by that.

  As described above, by offsetting the rear grip portion, it is possible to further reduce the weight while ensuring a hold feeling and grip force of the rear grip portion.

  Hereinafter, a fishing rod according to an embodiment of the present invention will be described with reference to FIGS. The fishing rod in the present embodiment includes a reel sheet 1 for attaching a reel. The reel sheet 1 has a cylindrical shape, also called a pipe sheet, and is mounted on a rod body (blank) of a fishing rod so as to be immovably fixed at a predetermined position. That is, the bag body passes through the reel sheet 1, and the reel sheet 1 is fixed to a predetermined position on the outer peripheral surface of the bag body by bonding or the like. The reel sheet 1 in this embodiment is for fixing a spinning reel. The spinning reel is located below the fishing rod in normal use. Therefore, the state where the reel faces downward is shown as a reference state in accordance with the state of use. In the following description, the radially outer side may be simply referred to as the outer side, and the radial inner side may be simply referred to as the inner side. Further, the direction of the center line of the heel body is the front-rear direction, the heel side is the front side, and the buttock side is the rear side. The side on which the spinning reel is located is the lower side, and the side opposite to it is the upper side. When the fishing rod is viewed from the upper side or the lower side, the direction orthogonal to the front-rear direction is defined as the left-right direction.

<Reel sheet 1>
The reel sheet 1 includes a cylindrical reel sheet main body 3, a cylindrical movable hood 4, and a fixed nut 5. The reel sheet main body 3 is externally mounted on the bag main body so as not to move, and integrally includes a fixed hood portion 6 for fixing one end portion of the reel leg. A male screw portion 7 is formed on the outer peripheral surface on the rear end side of the reel sheet main body 3, and a fixing nut 5 is screwed to the male screw portion 7. The movable hood 4 is for fixing the other end of the reel leg, and is mounted on the reel seat body 3 so as to be movable in the front-rear direction. In this embodiment, the fixed hood portion 6 is positioned on the front side to hold the front end portion of the reel leg, and the movable hood 4 is positioned on the rear side to hold the rear end portion of the reel leg and is movable with the fixed hood portion 6. The hood 4 holds the reel legs back and forth. The fixing nut 5 is located on the rear side of the movable hood 4 and moves the movable hood 4 in the front-rear direction and fixes it at a desired position. A cylindrical grip body 8 made of a grip material such as foam EVA or cork is attached to the outside of the front portion of the reel sheet body 3.

<竿 body>
The type of fishing rod is arbitrary, and may be a row rod or a swing rod. For example, in the case of a one-piece rod, it has a single continuous structure from the base to the tip. In the case of the two-piece rod, the fishing rod is composed of the first rod on the tip side and the second rod on the original side, and the reel seat 1 is provided on the second rod on the original side. The fishing rod of this embodiment is a two-piece rod, and is composed of a first rod (not shown) and a second rod shown in FIG.

  The second cocoon body has a structure in which two hollow skeletons are joined to each other. That is, the collar body is composed of a main chassis 20 located on the front side and a rear grip chassis 21 located on the rear side. The rear portion of the main housing 20 is inserted inside the front portion of the rear grip housing 21, and the main housing 20 and the rear grip housing 21 are overlapped and connected to each other over a predetermined length. The reel seat 1 is mounted on the main body so as to cover the overlapping portion of the main housing 20 and the rear grip housing 21 from the outside. That is, the reel seat body 3 is mounted on the front portion of the rear grip housing 21. The reel sheet main body 3 may be directly bonded to the outer peripheral surface of the rear grip housing 21 or may be bonded via a spacer. The grip body 8 covers the outer side of the front portion of the reel sheet body 3 and also covers the main casing 20 over a predetermined length. The cocoon body is formed by heating and baking prepregs having various shapes. Carbon fiber or glass fiber can be used as the prepreg reinforcing fiber. The main housing 20 may be solid.

<Rear grip housing 21>
The rear grip housing 21 is a housing integrally including a hollow rear grip portion 31. The rear grip part 31 is a part in which a predetermined length region on the rear end side of the entire length of the rear grip housing 21 is locally bulged outwardly in the radial direction. The rear grip portion 31 is located a predetermined distance rearward from the reel seat 1 and constitutes a predetermined length region including the rear end portion of the rear grip housing 21. Therefore, the rear grip portion 31 constitutes the rod bottom portion of the fishing rod. The rear grip portion 31 is used by applying an elbow or forearm of a hand holding a fishing rod, or holding it with a hand opposite to the hand holding the reel seat 1 when casting with both hands. The length of the rear grip portion 31 is arbitrary, but is long enough to be gripped by one hand, and is longer than the length corresponding to four fingers from the index finger to the little finger of a general adult hand. preferable.

  The rear grip housing 21 is composed of two front and rear regions, and is composed of a housing main portion 30 constituting the front portion of the rear grip housing 21 and a rear grip portion 31 constituting the rear portion of the rear grip housing 21. ing. The housing main part 30 forms a predetermined length region from the front end of the rear grip housing 21, and the length occupies more than half of the total length of the rear grip housing 21. Therefore, the housing main body 30 constitutes a main part of the rear grip housing 21 and is longer than the rear grip portion 31. The main body 30 is a straight portion having a substantially constant diameter, but may have a gradient. In this embodiment, the inner diameter of the main body 30 is substantially constant and the outer diameter of the main body 30 is also substantially constant. However, since the reel sheet 1 is mounted on the main body 30, A portion of the main portion 30 where the reel sheet 1 is mounted may be thickened by providing a reinforcing layer. The cross-sectional shape of the housing main part 30 is circular as shown in FIG.

<Rear grip part 31>
The rear grip part 31 is not a separate structure but an integral structure formed integrally with the rear grip housing 21. The rear grip portion 31 is larger than the housing main portion 30 and has a shape bulging outward in the radial direction with respect to the housing main portion 30. The rear grip portion 31 bulges greatly on the left and right sides and the lower side with respect to the main body portion 30, but hardly bulges on the upper side. In other words, the rear grip portion 31 bulges evenly to the left and right with respect to the main body portion 30, but does not bulge evenly up and down, and bulges with a bias toward the lower side. FIG. 6B to FIG. 8 show a cross-sectional shape of the rear grip portion 31. 6B to 8, the outer peripheral surface of the main body 30 is indicated by a two-dot chain line inside the cross-sectional shape of the rear grip portion 31, and the vertical direction of the main body 30 is shown in the vertical direction. The center line T1 and the center line T2 in the left-right direction are indicated by a one-dot chain line, and a circumscribed circle 100 circumscribing the cross-sectional shape is indicated by a two-dot chain line outside the cross-sectional shape of the rear grip portion 31.

<The upper surface 40 of the rear grip part 31>
The upper surface 40 of the rear grip portion 31 hardly bulges with respect to the outer peripheral surface of the main body 30 of the housing, and remains only slightly bulged. Therefore, when the rear grip portion 31 is viewed from one side as shown in FIGS. 1 and 4, the upper surface 40 of the rear grip portion 31 seems to extend substantially straight from the outer peripheral surface of the housing main body 30. The extent to which the rear grip portion 31 bulges upward is small. The curvature radius of the circumferential direction of the upper surface 40 of the rear grip part 31 is large, and the upper surface 40 is a curved surface close to a plane. In the cross-sectional shape of the rear grip portion 31 as shown in FIGS. 6B to 8, the radius of curvature of the upper surface 40 of the rear grip portion 31 is larger than the radius of the circumscribed circle 100. The diameter of the circumscribed circle 100 increases toward the rear side of the rear grip portion 31, but the radius of curvature of the upper surface 40 of the rear grip portion 31 is larger than that of the circumscribed circle 100, and has a curved shape close to a plane.

<Lower surface 41 of the rear grip portion 31>
On the other hand, the lower surface 41 of the rear grip portion 31 is greatly bulged downward with respect to the outer peripheral surface of the housing main portion 30. A front part of the lower surface 41 of the rear grip part 31 is formed with a sudden bulging part 42 that is continuous with the outer peripheral surface of the main body part 30 and bulges downward with a steep slope toward the rear side. In addition, a lower surface main portion 43 is formed at the rear portion of the lower surface 41 of the rear grip portion 31 so as to bulge downward with a gentle gradient or gradient 0 toward the rear side. The boundary portion between the sudden bulging portion 42 and the lower surface main portion 43 is an inflection point 44 of the lower surface 41, and the inflection point 44 is an angle at which the radius of curvature along the front-rear direction is locally reduced. The part is formed. The lower surface 41 (rapid bulging portion 42) on the front side from the inflection point 44 is a concave curved surface that is curved upwardly along the front-rear direction, and the lower surface 41 (lower surface main portion on the rear side from the inflection point 44). 43) is a convex curved surface curved in a downward convex along the front-rear direction.

<Side 45 of the rear grip 31>
The left and right side surfaces 45 of the rear grip portion 31 bulge symmetrically with respect to the main body portion 30. A suddenly expanding portion 46 is formed at the front portion of the side surface 45 of the rear grip portion 31 so as to widen with a steep slope toward the rear side. The rear portion of the side surface 45 of the rear grip portion 31 has a rear portion. A side main portion 47 whose width increases gradually toward the side with a gentle gradient or a gradient of 0 is formed. The length in the front-rear direction of the side main portion 47 is shorter than the length in the front-rear direction of the lower surface main portion 43, and the front end portion of the side main portion 47 is located on the rear side of the front end portion of the lower surface main portion 43. Yes. The bulge amounts of the left and right side main portions 47 from the housing main portion 30 are substantially the same, and the bulge amounts of the lower surface main portion 43 from the housing main portion 30 are also substantially the same.

<Change in cross-sectional shape of rear grip housing 21>
6 to 8 show changes in the cross-sectional shape of the rear grip housing 21. FIG. The cross-sectional shape of the housing main body 30 is a circular shape as shown in FIG. 6A, but the cross-sectional shape of the rear grip portion 31 is not a circular shape but a left-right symmetric non-circular shape. That is, the cross-sectional shape of the rear grip housing 21 gradually changes from a circular shape to a non-circular shape from the housing main portion 30 to the rear grip portion 31. Also in the rear grip portion 31, the cross-sectional shape gradually changes from the front side to the rear side as shown in FIGS.

  The cross-sectional shape in the vicinity of the front end portion of the rear grip portion 31, that is, the cross-sectional shape of the front side of the inflection point 44 of the lower surface 41 is a non-circular shape close to a circular shape as shown in FIG. The cross-sectional shape at the inflection point 44 of the lower surface 41 is a left-right symmetric non-circular shape that is significantly different from the circular shape, as shown in FIG. The cross-sectional shape at the inflection point 44 of the lower surface 41 is a shape that narrows toward the lower side, and has a substantially inverted triangular shape. From there, it bulges mainly in the left-right direction, and in the vicinity of the middle position of the rear grip portion 31, the cross-sectional shape is wider than that in FIG. 7 (a) as shown in FIG. 7 (b). A substantially inverted triangular shape is maintained. However, the curvature radius in the circumferential direction of the lower surface 41 of the rear grip portion 31 gradually increases from the inflection point 44 toward the rear side, and the lower surface 41 (the lower surface main portion 43) gradually increases toward the rear side. It is round. As shown in FIG. 8, in the vicinity of the rear end portion of the rear grip portion 31, the curvature radius of the lower surface 41 is further increased and the lower surface 41 is further rounded, and the cross-sectional shape is a substantially inverted triangular shape or a substantially inverted platform. It has a shape. In addition, corner portions 48 each having a locally reduced radius of curvature are formed at the boundary between the upper surface 40 and the left and right side surfaces 45, respectively. For example, when the cross-sectional shape is a substantially inverted triangular shape, the upper surface forms one side of the triangle, and the left and right side surfaces form two sides. However, the upper surface 40 and the left and right side surfaces 45 are not flat surfaces but curved surfaces that are curved outward in the radial direction. A corner 58 at the boundary between the upper surface 40 and the left and right side surfaces 45 is located above the center C1 of the main body 30.

<Offset>
Further, as shown in FIGS. 6B to 8, the outer peripheral surface of the main body 30 is indicated by a two-dot chain line, and the main body 30 is relatively above the cross-sectional shape of the rear grip 31. Is located. In other words, the rear grip portion 31 is offset downward with respect to the housing main portion 30, and the center C2 of the rear grip portion 31 is offset below the center C1 of the housing main portion 30. In position. The center C2 of the rear grip portion 31 is the position of the center of gravity in the cross-sectional shape of the rear grip portion 31, and the position of the center C2 of the rear grip portion 31 changes due to the change in the cross-sectional shape. In each cross-sectional shape of the rear grip part 31, the center C <b> 2 of the rear grip part 31 is located below the center C <b> 1 of the housing main part 30.

<Rear end opening and bottom plug 50>
As shown in FIGS. 4 and 5, a tail plug 50 is attached to the rear end of the rear grip housing 21. In the present embodiment, the rear end surface 21a of the rear grip housing 21 is not a surface orthogonal to the center line C1 of the rear grip housing 21, but is an inclined surface inclined along a predetermined direction. The inclined surface is inclined such that the upper part is located on the rear side and the lower part is located on the front side. Therefore, the upper surface 40 of the rear grip portion 31 extends rearward from the lower surface 41. As described above, the rear end face 21a of the rear grip casing 21 is formed by being cut obliquely. When the rear end face 21a of the rear grip casing 21, which is the opening end face, is viewed from the normal direction, FIG. ).

  Since the rear end face 21a of the rear grip housing 21 is cut obliquely, the tail plug 50 has a corresponding shape and is exposed to the outside from the rear grip housing 21. The 50 portion is also inclined. The configuration of the bottom plug 50 may be various, but in the present embodiment, a support member 51 and a buffer member 52 are provided. The support member 51 is preferably made of hard synthetic resin or metal, and the buffer member 52 is preferably made of rubber. The support member 51 includes an insertion tube portion 51 a that is inserted inside the rear end portion of the rear grip housing 21. The insertion cylinder portion 51 a supports the inner peripheral surface of the rear end portion of the rear grip housing 21 from the inside to prevent the rear end portion of the rear grip housing 21 from being crushed and damaged. The insertion cylinder portion 51a is fixed to the inner peripheral surface of the rear grip housing 21 by adhesion. Further, the rear end side of the support member 51 protrudes rearward from the rear end surface 21 a of the rear grip housing 21. The rear projecting portion of the support member 51 is formed with a collar portion 51b that abuts the rear end surface 21a of the rear grip housing 21 over the entire circumference from the rear side, and a portion on the rear side of the collar portion 51b of the support member 51. A shock-absorbing member 52 is attached. The rear end surface of the bottom plug 50 is a rear end surface of the buffer member 52, but is inclined in the same manner as the rear end surface 21a of the rear grip housing 21. The rear end surface of the rear plug 50 and the rear end surface 21a of the rear grip housing 21 are They are parallel to each other. Thus, the rear end surface of the bottom plug 50 is inclined, so that the upper part of the rear end portion of the fishing rod has a sharp shape. Therefore, when the rear end portion of the fishing rod is inserted into, for example, a cylindrical rod holder and the fishing rod is stood, the rear end portion of the fishing rod can easily enter the rod holder. Similarly, when the rear grip housing 21 is finished in the bag, it can be smoothly inserted into the bag from the bottom plug 50 side. Moreover, since the upper surface 40 of the rear grip part 31 becomes longer than the lower surface 41, the length and area of the surface to which an elbow etc. are applied can be expanded to the rear side.

  When the reel seat 1 of the fishing rod configured as described above is gripped with, for example, the right hand, the rear grip portion 31 can be gripped from the lower side with the left hand and double-hand casting can be performed. Since the rear grip portion 31 is offset downward, the rear grip portion 31 has a large amount of bulging downward. Therefore, when casting, the rear grip portion 31 can be easily grasped from the lower side. For example, when the fishing rod is swung forward in overhand casting, the right hand holding the reel seat 1 is swung out to the front, and at the same time, the left hand holding the rear grip portion 31 is pulled back in front of the chest. Since the rear grip portion 31 is offset downward, when swinging the fishing rod forward, the left hand holding the rear grip portion 31 is positioned away from the front by the offset amount. Thus, the rear grip part 31 can be attracted to the front with a large stroke. Therefore, the fishing rod can be swung out smoothly and the flight distance is extended.

  Further, although the cross-sectional shape of the rear grip portion 31 is non-circular, the radius of curvature of the lower surface 41 of the rear grip portion 31 is the rear side in the region behind the inflection point 44 of the lower surface 41 of the rear grip portion 31. Since the radius of curvature of the lower surface main portion 43 gradually increases toward the rear side, the rear portion of the rear grip portion 31 can be firmly held with the ring finger or the little finger. It is possible, and the uncomfortable feeling when gripping the rear part of the rear grip part 31 is also small. On the other hand, the radius of curvature of the front side portion of the lower surface main portion 43 of the rear grip portion 31 where the index finger or the middle finger hits is conversely small and has a sharp pointed shape. When the index finger or the middle finger is applied to the front portion, the front portion of the lower surface main portion 43 of the rear grip portion 31 is caught in the circumferential direction. Therefore, the hand is less likely to slip in the circumferential direction with respect to the rear grip portion 31, and the fishing rod is less likely to sway from side to side during casting. In this way, in the region on the rear side of the inflection point 44 on the lower surface 41 of the rear grip portion 31, the radius of curvature of the lower surface main portion 43 of the rear grip portion 31 is gradually increased toward the rear side, thereby making it easier to grip. Further, it is possible to prevent slipping of the hand in the circumferential direction while securing the thickness, and the rear grip portion 31 can be firmly grasped and cast.

  Further, a corner 48 having a locally reduced radius of curvature in the circumferential direction is formed at the boundary portion between the upper surface 40 and the left and right side surfaces 45 of the rear grip portion 31, and the corner 48 is in the front-rear direction. Therefore, the fingertip of the finger holding the rear grip 31 can be hooked on one of the left and right corners 48. Further, the palm, for example, the vicinity of the thumb ball can be pressed against the other corner 48. Therefore, the hand becomes more difficult to slip in the circumferential direction.

  Furthermore, since the corner | angular part where the curvature radius of the front-back direction became small locally is formed in the inflection point 44 of the lower surface 41 of the rear grip part 31, for example, an index finger can be hooked on the front side of the corner | angular part. Therefore, the hand gripping the rear grip part 31 at the time of casting becomes difficult to slip in the front-rear direction, and the rear grip part 31 can be firmly gripped. In the above description, the overhand cast is taken as an example, but the same applies to the case of an underhand cast that is thrown from below in boat fishing or the like.

  On the other hand, after casting, the elbow or the like of the right hand holding the reel seat 1 can be applied to the upper surface 40 of the rear grip portion 31. Since the upper surface 40 of the rear grip portion 31 is wide and has a curved surface close to a flat surface, the area to which the elbow or the like is applied is large, and the elbow or the like is easily adhered to the upper surface 40 of the rear grip portion 31. Therefore, the fishing rod can be firmly fixed between the hand holding the reel seat 1 and the elbow or the like, and the fishing rod is stabilized when hooking the fish or pulling or taking in the caught fish. In addition, by applying an elbow or the like to the rear grip portion 31, vibrations such as fish claws are transmitted to the elbow and the like, but the upper surface 40 of the rear grip portion 31 is a wide and curved surface close to a plane. Vibration will be transmitted to the elbow etc. with high sensitivity.

  On the other hand, the rear grip portion 31 is offset downward with respect to the housing main portion 30, and the bulging amount of the rear grip portion 31 to the upper side with respect to the housing main portion 30 is very small. Therefore, the volume of the rear grip part 31 as a whole is not so large. That is, the entire volume of the rear grip portion 31 is suppressed with respect to the bulging amount of the rear grip portion 31 to the lower side. For this reason, it is possible to reduce the weight while ensuring the hold feeling and gripping force of the rear grip portion 31.

  Furthermore, since the cross-sectional shape of the rear grip portion 31 is a substantially inverted triangular shape or a substantially inverted trapezoidal shape in the region on the rear side of the inflection point 44 of the lower surface 41 of the rear grip portion 31, it bulges downward. While securing the amount, the volume of the rear grip portion 31 can be suppressed and the weight can be reduced.

  In the present embodiment, the reel sheet 1 for attaching the spinning reel is provided. However, as shown in FIG. 9, the reel sheet 1 for attaching both-axis reels may be provided. Both reels are usually located above the fishing rod. The movable hood 4 and the fixed nut 5 are located on the front side of the reel sheet body 3, and the grip body 8 is located on the rear side of the reel sheet body 3. Note that the present invention can also be applied to a fishing rod that does not include the reel sheet 1.

  Moreover, in the said embodiment, although the rear-end surface 21a of the rear grip housing 21 was cut diagonally, the surface orthogonal to the centerline C1 may be sufficient. Furthermore, although the cross-sectional shape of the rear grip portion 31 is non-circular, it may be circular.
