The boot body comprises an outer layer formed by injection molding a rubber material, and an inner layer formed of fluorine-containing rubber. An injection gate for the outer layer is located at a portion of the outer layer opposing the rigid plate. Both an outer surface and an inner surface of at least a portion of the rigid plate having the through hole are covered with the rubber material supplied from the injection gate.
