When the handle 26 is rotated, the bolt rod 23 is screwed or unscrewed with respect to the bolt seat 25 according to the rotation direction. When the bolt rod 23 moves so as to be pushed out from the inside of the handle 26 as the handle 26 rotates, the pressing plate 22 moves forward with respect to the abutting plate 20, so that the corresponding contacting plate 20 and the pressing plate 20 are pressed. The bathtub wall is sandwiched between the plate 21 and the fixing member 11 is fixedly attached to the upper edge of the bathtub. In addition, the cushion material 21 similar to the said contact board 20 is affixed on the inner surface of the press plate 22 which will be press-contacted to the inner surface of a bathtub wall so that the surface of a bathtub wall may not be damaged. . On the other hand, when the bolt rod 23 moves so as to be pulled into the handle 26 along with the rotation of the handle 26, the pressing plate 22 moves backward with respect to the contact plate 20, so that the fixing member at the upper edge of the bathtub 11 is loosened.

  The handle member 12 is extended toward the outside of the bathtub and the support 27 erected on the fixing member 11, the handle 28 for bath extending toward the inside of the bathtub, and the tip of the support 27. And an outside bath handle 29. A pair of the support columns 27 are provided, and each of the support columns 27 is disposed on both sides of the outer surface of the contact plate 20. In this way, the support column 27 is arranged on the outer surface of the abutment plate 20 so that the base end portion of the support column 27 is arranged outside the bathtub rather than the outer surface A of the bathtub wall indicated by the one-dot chain line in FIG. ing. As a result, when the bathtub is covered, the support column 27 is prevented from interfering with the lid.

  The support column 27 is provided with a plurality of through-holes 27a, and through-holes such as pins and bolts are inserted into the through-holes 27a. Further, the through-holes are provided in the contact plate 20 (not shown). ), The support column 27 is erected on the fixing member 11. And the height adjustment of the handle member 12 with respect to the fixing member 11 can be performed by changing suitably the through-hole 27a which penetrates an insertion member, and the improvement of the usability of a user is achieved. Furthermore, the outer surface of the contact plate 20 is covered with a cover lid 20a, and the base end portion of the support column 27 is housed in the cover lid 20a together with the insertion member.

  The in-bath handle 28 is formed in a U-shape, and is provided so as to connect the distal end portions (upper end portions in the drawings) of the pair of support columns 27. The outside handle 29 is also formed in a U shape like the inside handle 28. The end of the in-bath handle 28 on the support column side and the end of the out-of-bath handle 29 on the support column side are connected to each other. The connected shape is annulus. Further, a protective cover 30 is wound around the auxiliary handle 13, the in-bath handle 28, and the out-of-bath handle 29 in order to prevent slipping when the user grips them. The material of the protective cover 30 is an elastomer such as SEBS (styrene-ethylene-butylene-styrene block copolymer) or SEPS (styrene-ethylene-propylene-styrene block copolymer). In the present embodiment, the color of the protective cover 30 is, for example, a long wavelength color such as red so that even a person with cataract can easily recognize it.

  The handle 26 is provided with a locking member 31 on the outer peripheral surface of the other end. The locking member 31 is formed in an annular shape, and a female screw is threaded on the inner peripheral surface thereof. On the other hand, a male screw is threaded on the outer peripheral surface of the other end of the handle 26, and the locking member 31 is screwed to the other end of the handle 26 which is the operation member. When the locking member 31 is rotated with respect to the handle 26 in a predetermined direction, the locking member 31 moves with respect to the handle 26 and approaches the second clamping body 16 and the second clamping body. The outer surface of 16 is pressed against the periphery of the support hole 24 constituting the support portion.

  In the bathtub handrail 10, when the fixing member 11 is fixed to the bathtub wall, the pressing plate 22 is previously separated from the contact plate 20 by a predetermined distance. The bathtub wall is located between. Next, the handle 26 is rotated, the pressing plate 22 is pressed against the bathtub wall, and the bathtub wall is sandwiched between the contact plate 20 and the pressing plate 22. And while holding the state which clamped the bathtub wall with the contact plate 20 and the press plate 22, this locking member 31 is rotated to a predetermined direction, and this locking member 31 is made to the outer surface of this 2nd clamping body 16. Press contact. Then, a frictional force is generated between the locking member 31 and the outer surface of the second clamping body 16, and the rotation of the locking member 31 is restricted. The rotation of the combined handle 26 is suppressed. When the rotation of the handle 26 is thus suppressed, the rotation of the bolt seat 25 to which the handle 26 is fixed is also suppressed, and the movement of the bolt rod 23 is further suppressed. As a result, even if vibration, external force, etc. are transmitted to the bolt rod 23, the bolt seat 25, and the handle 26, the respective rotations or movements are suppressed, so that loosening of the fixing member 11 to the bathtub wall can be suppressed.

  In the above embodiment, the operation member does not necessarily need to be the handle 26 having the shape shown in each drawing, and may be a rod shape, a disk shape, or the like. Further, when such a rod-like or disc-like operation member is used, the operation member may be attached to the bolt rod 23 without using the bolt seat 25. Further, the locking member 31 is not necessarily screwed with the handle 26, and may be screwed with the bolt rod 23 inside the fixing member 11, for example. Further, the locking member 31 is not limited to the configuration of the embodiment as long as the rotation or movement of at least one of the bolt rod 23, the bolt seat 25, and the handle 26 can be suppressed. 26 and a wedge member that is press-fitted between the outer surface of the second sandwiching body 16 and a rubber member.
