PROBLEM TO BE SOLVED: To increase strength for load by forming a supporting surface having an angle different from that of a mounting surface of a grip on a bathtub and forming a reinforcing plate into a shape capable of contacting with a rear side of both surfaces of the mounting surface and the supporting surface, in a grip mounted on the surface side of the bathtub by interposing the reinforcing plate on the rear surface of the bathtub. SOLUTION: When a grip 2 is mounted on an inside surface 1a of a bathtub in parallel to an upper edge surface 1b of the bathtub, a reinforcing plate 3 is interposed on a rear side and mounting strength of the grip 2 is increased. This reinforcing plate 3 is formed by integrally providing a vertical contact surface piece 3a abutting on a rear side of the inside surface 1a of the bathtub, an inclined surface piece 32b at an upper end of the vertical contact surface piece 3a and a horizontal contact surface piece 3c coming into contact with a rear side of the upper edge surface 1b of the bathtub. When the grip 2 is mounted, the vertical contact surface piece 3a is fixed to the rear side of the inside surface 1a of the bathtub via adhesive 7, a bolt 5 is tightened on the grip 2 through a washer 4 and the reinforcing plate 3 from the rear side. As a result, load applied to the grip 2 can be dispersed via the reinforcing plate 3. |
