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

3. 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.

4. A toilet seat comprising:

a seat front member;

a seat rear member; and

a joint part between the seat front member and the seat rear member,

wherein a shape of a processed surface of the joint part between the seat front member and the seat rear member is formed in a curved shape that protrudes outward on a side of the seat rear member and formed in a linear shape on a side of the seat front member in a cross section perpendicular to a direction in which the joint part extends.

5. The toilet seat of claim 4,

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

an end of the processed surface on a side of the seat rear member is away from an end of the protrusion on a side of the processed surface by 10 mm or more.
