Manufacture of steering wheel

Abstract

Abstract PURPOSE:To improve the external appearance of a steering wheel and its touching feel, by setting a core material of the steering wheel to one of the metal molds and fitting these molds introducing a fiber for constituting a cloth-state outermost layer into a cavity to be formed by resin molding. CONSTITUTION:A steering wheel core material 3 is set to a mold surface 5a in one metal mold 5. Thereafter fitting both the metal molds 5, 6, a short fiber 4a, which constitutes a cloth-state outermost layer 4, is introduced floating in a cavity 7. This short fiber 4a is uniformly and closely attached to the mold surfaces 5a, 6a of the metal molds 5, 6. Under this condition, a synthetic resin molding material 12 is injected into the cavity 7. After the synthetic resin molding material 12 is solidified, a product is removed by separating the metal molds 5, 6. In this way, a steering wheel 1, in which a synthetic resin made steering wheel main body 2 coats its total surface with the cloth-state outermost layer 4, is obtained improving external appearance of the steering wheel and its touch feeling.
