It can be moved forward. At this time, if the handle plate 26 is further rotated while the pressing plate 9 is in contact with the side wall 1 of the bathtub, the turning force when turning the handle knob 26 becomes excessive, but if the turning force becomes excessive, the torque is increased. The lock washer 32 runs idle, and the turning force for turning and operating the handle knob 26 is not transmitted to the bolt shaft 25. Therefore, even if the handle knob 26 is rotated with an excessively strong force while the pressing plate 9 is in contact with the side wall 1 of the bathtub, the force from the handle knob 26 is not transmitted to the bolt shaft 25, and the excessive force Thus, the pressing plate 9 can be prevented from being pressed against the side wall 1 of the bathtub, and the side wall 1 of the bathtub can be prevented from being damaged.

  And in the handrail A for bathtubs formed as mentioned above, since the main body tool 5 which provided the handrail 4 is provided with the reinforcing rib 10 in the upper piece 2 or the vertical piece 3, The upper piece 2 and the vertical piece 3 can be reinforced. Accordingly, it is possible to reduce the thickness of the upper piece 2 and the vertical piece 3 without reducing the strength, and it is also possible to form the upper piece 2 and the vertical piece 3 with light aluminum which is not high in strength but lightweight. The handrail A for bathtubs can be reduced in weight.

  Further, the slide bar 12 of the press receiving device 7 is fixed to the upper piece 2 by screwing a screw 13 into the screw hole 15 in a state where the slide bar 12 is inserted into the slide groove 11 and fitted therein. For this reason, even if the stress that causes the slide bar 12 to move in the width direction or the stress that causes the twist to act on the slide bar 12, the slide bar 12 moves in the width direction or the twist direction by the reinforcing ribs 10 on both sides in the slide groove 11. The stress 13 is not concentrated on the screw 13 and the screw 13 is not detached from the screw hole 15, and the connection of the pressure receiving tool 7 to the main body tool 5 is made firm. It is something that can be done.

  As described above, the slide receiver 12 is slidably inserted into the slide groove 11 formed between the reinforcing ribs 10 and fixed to the main body tool 5 by fixing the screw 13 to the slide receiver 12. Therefore, the slide bar 12 can be slid while being positioned using the slide groove 11 formed between the reinforcing ribs 10, and the adjustment of the distance between the main body tool 5 and the pressure receiving tool 7 can be performed smoothly. At the same time, the position of the slide bar 12 is fixed in a state of being fitted in the slide groove 11, so that the main body tool 5 and the pressure receiving tool 7 can be firmly coupled.
