Abstract
A release member molding method for mounting a metallic plate in a main body of a release member by insert-molding. The release member is to be provided to be integrally rotatable with a reel accommodated in a case, and to move a locking member from a locking position that locks rotation of the reel to an allowing position that allows rotation of the reel. The metallic plate touches a sliding protrusion portion of the locking member at a touching surface of the release member. The release member molding method includes an arranging step of arranging the metallic plate in a die and a molding step of charging a resin material into the die and molding the main body in which the metallic plate is mounted. The die contacts a portion of the metallic plate that excludes the touching surface, and the die does not contact the touching surface.
