By tightening the two screws 50, the shower hook main body 21 is fixed to the attachment part 15. A cap 23 is attached to the shower hook body 21. With the above steps, the installation work of the shower hook 20 is completed.

A state in which the shower hook 20 is attached to the wall 11 of the bathroom 10 will be explained. The screw 50 passes through the component through hole 22, the sleeve 40, and the wall through hole 16, and is tightened into the screw hole 33 of the reinforcing member 30. The reinforcing member 30 and the shower hook 20 sandwich the attachment part 15.

The sleeve 40 fits into the front region of the wall through hole 16. The collar portion 42 of the sleeve 40 is sandwiched between the front surface of the attachment portion 15 and the back surface of the shower hook 20. The sleeve 40 fills the gap between the inner peripheral surface of the wall through hole 16 and the outer peripheral surface of the screw 50. The back end of the sleeve 40 is located inside the wall through hole 16. A clearance 17 is formed in a region of the wall through-hole 16 on the back side of the sleeve 40.

The shaft portion 52 of the screw 50 includes a portion disposed inside the sleeve 40 (referred to as a first shaft portion 53) and a portion disposed in the screw hole 33 of the reinforcing member 30 (referred to as a second shaft portion 54). ) Movement is restricted in two places. The first shaft portion 53 of the screw 50 is restrained from moving in the front-back direction (the axial direction of the screw 50), the vertical direction, and the left-right direction (the direction intersecting the axial direction of the screw 50). The second shaft portion 54 of the screw 50 is restrained from moving in front and back directions, up and down directions, and left and right directions by the reinforcing member 30 . This restricts the screw 50 from sliding in the axial direction and in the direction crossing the axial direction.

The operation and effects of the embodiment configured as described above will be explained. Shower hooks are repeatedly subjected to horizontal and vertical loads during use. The horizontal load is applied, for example, when a shower head (not shown) held on a shower hook is swung left and right. The vertical load is applied by attaching and detaching a shower head (not shown) to and from the shower hook. Conventionally, when such a load is repeatedly applied to the shower hook, the screw becomes loose, and the screw is displaced in the through hole formed in the attachment portion, causing the shower hook to wobble. It has been difficult to improve such looseness because even if the screw is tightened again, the screw is displaced due to the clearance of the through hole.

On the other hand, the attachment structure 14 of the shower hook 20 includes a reinforcing member 30 and a sleeve 40. The reinforcing member 30 is arranged on the back side of the wall 11. The sleeve 40 fits inside a wall through hole 16 formed through the wall 11. The screw 50 passes through the component through hole 22 formed in the shower hook 20, the sleeve 40, and the wall through hole 16, and is tightened into the screw hole 33 formed in the reinforcing member 30. According to this configuration, the displacement of the screw 50 within the wall through-hole 16 is restricted by the sleeve 40, so that shaking of the shower hook 20 can be suppressed.

The sleeve 40 fills the gap between the inner peripheral surface of the wall through hole 16 and the outer peripheral surface of the screw 50. According to this configuration, shaking of the shower hook 20 can be prevented.

The sleeve 40 has a flange 42 that protrudes outward from the outer peripheral surface. According to this configuration, since the sleeve 40 can be positioned by the collar portion 42, the work of attaching the shower hook 20 can be easily performed.

The back end of the sleeve 40 is located closer to the front than the back end of the wall through hole 16. According to this configuration, since the sleeve 40 does not protrude from the back side of the wall 11, the flat reinforcing member main body 31 can be attached to the back side of the wall 11.
