At the same time, damage caused when the toilet lid 12 collides with the functional section 2 can be reduced.

According to the toilet lid 12 of this embodiment described above, the following effects are achieved. In the toilet lid 12 of this embodiment, the toilet lid 12 is configured to be rotatable around a rotation axis J, and includes a bush receiving portion 7 in which a bush 6 with a stopper portion 65 is disposed. , the bush receiving portion 7 has a surrounding rib 73 formed to surround a space in which the bush 6 is arranged. Therefore, since the bush 6 with the stopper portion 65 is surrounded by the surrounding rib 73, the strength of the bearing of the toilet lid 12 can be improved. Since the bush 6 with the stopper part 65 is surrounded by the enclosing rib 73, the bush 6 with the stopper part 65 can be placed in the bush receiving part 7 in a state where the appearance is less noticeable. Thereby, the design quality can be improved.

In this embodiment, when the toilet lid 12 is in the open position, the enclosing rib 73 includes a front rib 731 and an upper rib 732. Therefore, due to the surrounding rib 73, the front side of the bush 6 can be hidden by the front side rib 731, and the upper side of the bush 6 can be hidden by the upper side rib 732. Thereby, by hiding the bush 6 on the front side and the upper side, the bush 6 can be arranged in the bush receiving part 7 in a state where the appearance is less noticeable. Therefore, the design quality can be improved.

In this embodiment, the front rib 731 is formed in a curved shape, and the upper rib 732 is formed in a planar shape. Therefore, since the front rib 731 is formed in a curved shape, when the toilet lid 12 rotates, the front rib 731 rotates while avoiding the convex portion 334 that forms the hinge arrangement space 33 in the top cover 32 of the cover member 3. Therefore, when the surrounding rib 73 rotates, the cover member 3 of the functional section 2 can be prevented from interfering with the rotation of the surrounding rib 73.

In this embodiment, the bush receiving portion 7 further includes a side extending plate 71 and an end extending plate 72 that intersects the side extending plate 71, and the surrounding rib 73 has a side extending plate 71. It stands upright laterally from the existing plate 71, and the surrounding rib 73, the side extending plate 71, and the end extending plate 72 are integrally formed. The enclosing rib 73 is arranged such that the upper portion thereof has a first gap S1 between it and the end extension plate 72.

If the surrounding rib 73 is connected to the end extension plate 72 without the first gap S1, sink marks may occur at the connected portion when the toilet lid 12 is molded with resin. There is sex. In contrast, in the present disclosure, the upper portion of the enclosing rib 73 is arranged with the first gap S1 between it and the end extending plate 72. Therefore, by forming the enclosing rib 73 with the first gap S1, it is possible to suppress the formation of sink marks when molding the toilet lid 12 with resin.

This embodiment includes a bush 6 disposed in the bush receiving part 7, and the bush 6 has a protruding stopper part 65 that comes into contact with the functional part 2 when the toilet lid 12 is in the open position. As a result, when the toilet lid 12 moves from the open position to the closed position, the protruding stopper part 65 of the bush 6 collides with the bush abutting part 333a, limiting the rotational position so that the toilet lid 12 does not open any further. At the same time, damage caused when the toilet lid 12 collides with the functional section 2 can be reduced.

The preferred embodiments of the present disclosure have been described above. The present disclosure is not limited to the embodiments described above, and can be modified as appropriate.
