As shown in FIGS. 26 and 27, a guide plate 51 is provided on the upper portion of the handle 50 so as to be tiltable in the width direction of the blade K, and the guide plate 51 is provided with a long groove 52 extending in the lateral direction. There is. And the guide plate
A blade body mounting member 53 for blade mounting is provided so as to be slidable laterally along the blade 51, and a guide pin 54 is projectingly provided at the center of the blade body mounting member 53. The guide pin 54 is slidable in the long groove 52, and its tip end is linked with a restoring means R for restoring the blade mounting member 53 to its original position when tilting and sliding.

[Problems to be Solved by the Invention] However, in the above safety razor, as shown in FIG. 28, the blade mounting member 53 itself laterally traverses along the guide plate 51, so that the blade mounting member 53 during use is in use. And the relationship between the handle and the handle 50 are not constant. That is, the blade mounting member 53
The left and right ends of the upper blade did not always protrude from the upper part of the handle 50 in the left-right direction by the same length. For example, when the guide plate 51 tilts to the left, the blade has a protrusion length to the left of the handle 50 that is longer than the protrusion length to the right, and conversely, when the guide plate 51 tilts to the right, it moves to the right. The projecting length of was long.

したがって、使用時において使用者は刃体Kの左右位置
がつかみにくく、使いにくいという欠点があった。
Therefore, there is a drawback that the user cannot easily grasp the left and right positions of the blade body K during use, which makes it difficult to use.

As shown in FIG. 1, the tips 15 are provided on both left and right sides of the main body 6.
a pair of support arms 15 in which a projects upward from the main body 6,
The shafts 15b are attached so as to be rotatable in the directions toward and away from each other. Both support arms 15 are constantly urged by springs 16 interposed between them and the main body 6 in a direction in which tips 15a approach each other, and the urging force causes the replaceable blade cartridge L to be supported in a sandwiched manner. It is like this.

As shown in FIG. 5, the safety razor of the present embodiment configured as described above has a solid line when there is no difference in the resistance applied to the left and right ends of the blade body K on the spare blade cartridge L during use. As shown by, the handle 1 and the blade mounting member 5 are T-shaped, and the blade mounting member 5 is not tilted in the width direction of the blade K, but due to the difference in beard density, thickness, etc. Blade K
When there is a difference in the resistance applied to the blade body mounting member 5, the blade body mounting member 5 tilts in the width direction of the blade body K due to the difference in the force, as indicated by the two-dot chain line. Therefore, it is possible to cut off and improve the shaving taste.

In this case, the blade mounting member 5 resists the elastic force of the leaf spring 11 and bends the elastic portion 13 of the leaf spring 11 to incline in the width direction of the blade K about the support shaft 9. If there is no difference in resistance applied to the blade body K of the inclined blade body mounting member 5, the restoring force of the leaf spring 11 bent by the tilting of the blade body mounting member 5 causes the engaging portion to move.
The front surface 14a of 14 transmits the blade body mounting member 5 and returns it to the original position again. When the blade body mounting member 5 tilts, the tilting occurs only around the support shaft 9, so that the blade body mounting member 5, that is, the blade body K, is different from the conventional example even in the tilted state, and is always above the handle 1. The same length in the left-right direction. Therefore, the left and right positions of the blade body K are easily grasped, and this safety razor is easy to use.

加えて、板バネ11の両端を刃体取付部材5の両収容孔3b

In addition, both ends of the leaf spring 11 are connected to both accommodation holes 3b of the blade mounting member 5.
The direction in which the elastic force of the leaf spring 11 acts coincides with the tilting direction of the blade mounting member 5, that is, the blade K.
Therefore, the leaf spring 11 is easily bent, and the blade body mounting member 5
Is smoothed, and the blade body mounting member 5 is smoothly restored to its original position by the restoring force of the leaf spring 11. Further, since the leaf spring 11 is engaged with the blade attachment member 5 at a position apart from the support shaft 9, the blade K responds to a slight difference in resistance applied to the blade K, and the blade K reacts to the resistance. Tiltability is also improved.

そして、板バネ11はヘッド部1aと刃体取付部材5の内部

In the safety razor of this another example, instead of the support shaft 9 in the first embodiment, a support shaft 9a is used which is formed so as to be bent rightward at the intermediate portion and then extends upward again. The shaft hole 7 of the blade mounting member 5 is provided in the right part. The head portion 1a and the blade mounting member 5 are provided with accommodating holes 3a and 3b only in the left portion. Only the left elastic portion 13 is formed on the leaf spring 11a, and the elastic portion 13 has a front end portion 13a that bends forward and a front end portion 13a that bends rearward. Both engagement surfaces 14a are engaged with both front and rear surfaces inside the accommodation hole 3b. In the safety razor configured as described above, when the blade body mounting member 5 is inclined due to the resistance difference applied to the right and left ends of the blade body, the left side portion of the blade body mounting member 5 may be inclined more than the right side portion. Has become. Even in such a case, the blade body protrudes from the upper portion of the handle 1 in the left-right direction by the same length, so that the left-right position of the blade body can be easily grasped.

When the blade mounting member 5 tilts, the tilting only occurs around the support shaft 9, so that the blade mounting member 5, that is, the blade body is different from the conventional example even in the tilted state. The same length in the left-right direction.
Therefore, the left and right positions of the blade body are easy to grasp, and this safety razor is easy to use. Further, in this embodiment, since the leaf spring 21 has a ring shape, when a difference in resistance applied to the left and right ends of the blade body occurs during use, as shown by a two-dot chain line in FIG. Leaf spring 21 due to the inclination of 5
The ring portion 21a is twisted in the circumferential direction around the support shaft 9 with the upper portion thereof fixed to the blade attachment member 5. In this case, since the leaf spring 21 has the ring portions 21a protruding to the left and right sides, the circumferential deformation of the support shaft 9 can be facilitated by utilizing the protruding portions to the left and right sides. Therefore, the inclination of the blade attachment member 5 also reacts to a slight difference in the resistance applied to the blade, and the inclination of the blade with respect to the resistance is also improved.
