Claims

[Scope of Claim for Utility Model Registration] The boot body is provided with a cylindrical connector for connection to a communication pipe for adjusting the internal pressure of the left and right steering boots, and the cylindrical connector and the boot body are integrated. The cylindrical connector protrudes outward from the boot body substantially in the radial direction of the boot body on the side where the boot body has a large diameter, and the cylindrical connector A steering boot molding device having a bending portion that can be bent in a direction transverse to the axis of a connector, comprising: a core mold having an outer shape corresponding to the inner shape of the boot body; a pair of half-split molds that are matched to form a recess of a shape corresponding to the shape, and that cooperate with the core mold to form a cavity for forming the boot body; and a pair of half-split molds that form a cavity for forming the boot body; Forming an inner shape of the cylindrical connector that can be freely inserted into a hole provided in the radial direction of the core mold through a hole provided in the split surface of the mold and movable in the radial direction of the core mold. and a pin that cooperates with the pin to form a cavity that forms the cylindrical connector and is continuous with the cavity that forms the boot body on the split surface of the pair of half molds. , a recess having a shape corresponding to the outer shape of the cylindrical connector, and at least one of the recess having a shape corresponding to the outer shape of the cylindrical connector and the pin, the cylindrical A steering boot molding device, comprising a mold portion for forming the bent portion of the connector.
