Steering wheel

摘要

A steering wheel incorporates a hard portion bonded to the overall circumference in the cross-sectional circumferential direction of a ring portion and a soft portion molded to cover the core metal of the ring portion and softer than the hard portion, the hard portion and the soft portion being disposed in the planar circumferential direction of the ring portion. An extended portion extending from the soft portion is disposed on the surface of the core metal of the ring portion at a position on the inside of the hard portion. The steering wheel enables the hard portion and the soft portion to be formed around the core metal of the ring portion by collective injection molding. The core metal of the ring portion has an inverted U-shape cross sectional shape and made of die-cast metal formed by die-casting. When the two hard portions having different volumes are molded, time periods required to complete injection of a material for molding into each cavity of the mold for molding each hard portion are made to be substantially the same to mold the hard portions. A coating layer can be provided for the surface of the hard portion. A leather is bonded to the surface of the soft portion. Support surfaces for supporting the inner surfaces of the ends of the leather and projection projecting into the inner surface of the soft portion are formed at the end of the hard portion. The coating layer is as well as applied to the outer surface of the support portion so as to bond the soft layer and the leather to the hard portion.
