In the remote-operated drain plug device, the operation unit for performing the opening / closing operation is naturally arranged so as to be exposed on the front side of the drainage device such as a wash basin or a bathtub. On the other hand, the release wire and the support member for operating the valve member are arranged on the back side of the drainage device so as not to obstruct the design and use of the drainage device. For this reason, in order to connect the operation part to the valve member with a release wire or the like, it is necessary to provide a hole penetrating from the front side to the back side of the drainage device. In the above conventional example, the operation portion mounting hole corresponds to this through-hole.
However, in order to provide the through-hole, there is a problem that it is necessary to perform an opening operation on a washstand, a bathtub, or the like, which causes troublesome processing and may damage the drainage device. In addition, when opening drainage equipment at factories, etc., this opening work is almost always done using a jig such as a drill, and it is virtually impossible to open it at home after completion of construction.
