Abstract

Provided is a method of manufacturing a toilet seat that is formed by joining together a seat front member and a seat rear member. The method includes a cutting step of forming a processed surface of a joint part between the seat front member and the seat rear member by cutting the joint part between the seat front member and the seat rear member with a cutting tool having a curved cutting blade part such that the shape of the processed surface is formed in a curved shape in which the seat rear member side thereof protrudes outward in a cross section perpendicular to the direction in which the joint part extends.

Claims

1. A method of manufacturing a toilet seat formed by joining a seat front member and a seat rear member together,

the method comprising a cutting step of forming a processed surface of a joint part between the seat front member and the seat rear member by cutting the seat front member and the seat rear member at the joint part between the seat front member and the seat rear member using a cutting tool including a curved cutting blade part such that a shape of the processed surface is formed in a curved shape in which a side of the seat rear member protrudes outward in a cross section perpendicular to a direction in which the joint part extends.

2. The method of manufacturing a toilet seat of claim 1,

wherein the seat rear member has a protrusion protruding from a seat rear portion of the seat rear member included in a rear surface of the toilet seat, and

the curved cutting blade part is formed such that an end of the curved cutting blade part on a side of the protrusion is away from an end of the protrusion on a side of the processed surface by 10 mm or more during the cutting step.
