Toilet seat and method of manufacturing a toilet seat
A toilet seat includes a body, a bottom plate, and a joining member. The body includes a seating part and a side wall part. The side wall part extends from each of an inner end and an outer end of the seating part. The bottom plate includes a bottom plate part and a protrusion part. The bottom plate part and the seating part face each other. The protrusion part protrudes laterally from the bottom plate part and is configured to be pressed by an end of the side wall part. The joining member joins the body and the bottom plate. The joining member is formed of a filling material poured to closely contact a side surface of the bottom plate part and a non-pressing surface other than a surface pressing the protrusion part on the end of the side wall part.
1. A toilet seat, comprising:
a body including a seating part and a side wall part, the side wall part extending from each of an inner end and an outer end of the seating part;
a bottom plate including a bottom plate part and a protrusion part, the bottom plate part and the seating part facing each other, and the protrusion part protruding laterally from the bottom plate part and being configured to be pressed by an end of the side wall part; and
a joining member joining the body and the bottom plate, the joining member being formed of a filling material poured to closely contact a side surface of the bottom plate part and a non-pressing surface other than a surface pressing the protrusion part on the end of the side wall part, at least a part of a side surface of the joining member being exposed to an exterior, wherein
the body includes a groove formed on the non-pressing surface of the side wall part.
2. The toilet seat according to claim 1 , wherein:
the bottom plate includes an extension part extending laterally along a bottom surface of the bottom plate part; and
the joining member closely contacting the non-pressing surface of the side wall part, the side surface of the bottom plate part, and a surface other than a surface along the bottom surface of the bottom plate part on the extension part.
3. The toilet seat according to claim 2 , wherein
the extension part is formed in such a manner that a thickness of the extension part is reduced toward a distal end of the extension part.
4. The toilet seat according to claim 1 , wherein:
the side wall part and the bottom plate part are formed in such a manner that an inner wall of the side wall part and an outer peripheral wall of the bottom plate part are pressed by and contact one another; and
the body and the bottom plate are configured in such a manner that the joining member does not flow into a space defined by the body and the bottom plate.
