Note that the first mold has a molding space corresponding to the covered cylindrical body, and the second mold has a molding space corresponding to the base resin material 2.
Multi-stage (multilayer) molding is performed by molding a covered cylindrical body using a first main mold and a first sub-forming mold, and then changing the first sub-forming mold to a second sub-forming mold. Can be implemented. Note that by combining the first main mold and the second sub mold, a molding space corresponding to the base resin material 2 is formed, and by combining the first main mold and the second mold, the flat part 23 is formed. A molding space corresponding to a covered cylindrical body is formed in which the spaces such as the above are closed.

For the base resin material 2, for example, filling of the first resin material corresponding to the covered cylindrical portion 21 and filling of the second resin material corresponding to the flat portion 23 and the groove portion 25 are performed at the same time. It can be obtained by Note that "at the same time" here means that after one of the first resin material and the second resin material is filled, one of the resin materials solidifies (becomes in a state where it can maintain its own shape). This means that the other resin material is filled up to the point where the other resin material is filled.
That is, the method for manufacturing the base resin material 2 includes the step of manufacturing the base resin material 2 by molding the covered cylindrical portion 21, the flat portion 23, and the groove portion 25 at the same time.
For example, a mold having a first molding space for the covered cylindrical part 21 and a second molding space for the flat part 23 and the grooved part 25 is installed such that the first molding space is located on the lower side. However, this can be carried out by injecting a predetermined amount of the first resin material into the first molding space from below, and then injecting the second resin material into the second molding space from above.
