The grip piece includes a linking base portion that covers at least both surfaces of the end portion of the linking protruding piece of the body, and a grip portion that extends from the linking base portion. The grip piece is formed and is, at the same time, linked to the linking protruding piece of the body by flowing a plastic material from one side of the linking protruding piece that positions in the space of the mold. A plastic material inflow groove that extends from the free end thereof toward the lower end of the skirt wall is formed on the side of the other surface of the linking protruding piece of the body.
