Abstract
Abstract In a leather-covered steering wheel comprising, a metal core including a ring core section and a plurality of spoke core sections, an elastic member for covering the ring core section and the end portions of the spoke core sections thereof at the side of the ring core section, a plurality of plates for maintaining the configuration of the elastic member which are higher in hardness than the elastic cover layer and are formed in correspondence with the peripheral configurations of the end faces of the portions of the elastic cover layer which cover the metal cores in the spoke section are arranged between the leather and the end faces, whereby the number of manufacturing steps and the manufacturing cost are reduced accordingly, and the steering wheel is maintained fine in external appearance.
