  Further, since the front base member 12 is detachably connected to the rear base member 11 and the upright member 20 via the slide base portion 13 and the slide portion 14, when the toilet handrail 1 is installed in the toilet, By storing the toilet handrail 1 in the toilet with the front base member 12 removed, and reattaching the front base member 12 in the toilet, it can be installed smoothly and reliably in a narrow toilet.

  In addition, since the pair of pressing members 35 that respectively press the left and right side wall surfaces SW of the toilet are attached to the main body portion, the left and right side wall surfaces SW of the toilet are pressed by the pressing members 35, so that the base member 10 is A reduction in installation strength due to the division into the rear base member 11 and the front base member 12 can be suppressed.

  In the above-described embodiment, in order to correspond to the water-saving toilet bowl B, hemispherical accessory parts are attached to the base part 48a fitted in advance to the universal joint 47 of the contact body 48 constituting the pressing part 45. 48b is attached, but the shape of the accessory part 48b attached to the base part 48a is not limited to a hemispherical shape, and may be appropriately set according to the shape of the toilet bowl to be attached. A plurality of types of accessory parts having different shapes may be prepared corresponding to toilet bowls having different shapes.

  As described above, the water-saving toilet bowl B having the recessed portion hb in which the upper portions of the left and right side surfaces of the toilet body Bb are greatly recessed inward and the expanded portion eb that gently expands outward from the recessed portion hb is provided. When installed in the toilet, for example, as shown in FIGS. 11 to 13, instead of the above-described hemispherical accessory part 48 b, the upper outer surface extending from the hollow part hb of the toilet body Bb to the enlarged part eb is provided. The accessory part 48c having a contact surface may be mounted on the base part 48a.

  As shown in FIGS. 12 and 13, the accessory 48c includes a synthetic resin main body member MM and a rubber sheet member SM attached to the main body member MM. The surface forms a contact surface.

  The main body member MM is inclined so as to be along a curved surface whose tip is curved along the hollow portion hb of the toilet body Bb and an upper end portion of the enlarged portion eb of the toilet body Bb continuously connected to the curved surface. The sheet member SM is adhered from the curved surface to the inclined surface.

  Accordingly, the abutment body 48 having the accessory part 48c attached to the base part 48a is brought into contact with the upper outer surface from the hollow part hb to the enlarged part eb of the toilet body Bb, so that the water-saving toilet B The surface can be reliably pressed from obliquely below, and can be installed in a more stable state as compared with the case where the above-described hemispherical accessory 48b is used.

  Further, in each of the above-described embodiments, the accessory parts 48b and 48c are attached to the base part 48a so as to correspond to toilet bowls having different shapes. However, the present invention is not limited to this, and each toilet bowl having a different shape is used. Alternatively, a handrail for toilet bowl provided with contact bodies 48 having different shapes may be prepared.
