In this example, the pair of support pins 138 are engaged with the pair of support holes 142 so that the female screw holes 132 and the through holes 134 can be automatically matched with each other. The work of aligning with the hole 134 is also unnecessary, and the work of screwing the screw member 136, that is, the work of fastening the pump unit 106 and the toilet body side plate 26 becomes easier.

Although the embodiment of the present invention has been described in detail, this is merely an example . For example, in the above embodiment, the decorative cover member 34 is formed separately from the toilet seat side plate 24, but it is also possible to form this integrally with the toilet seat side plate 24.

The present invention can be applied to a toilet seat elevating device in which an airbag is integrally attached to a toilet body and a toilet seat. For example, the present invention can be applied to various configurations without departing from the gist of the invention. It is possible.
