る。In the leather-wound steering wheel according to the present invention, the leather is fitted into the annular groove provided in the hard portion while the vicinity of the terminal directly contacts the outer peripheral surface of the support portion in the hard portion. Since the leather terminal can be arranged to be bent not at the soft synthetic resin part but at the corner of the support part provided at the hard part, there is no rounding at the leather terminal and the appearance of the leather terminal Can be improved.

理を容易にすることができる。Therefore, in the leather-wound steering wheel of the present invention, the hard portion and the soft synthetic resin portion which is softer than the hard portion are arranged around the core of the ring portion along the forming direction of the ring portion. Therefore, even if leather is arranged around the soft synthetic resin part, there is no rounding at the leather terminal, the appearance of the leather terminal can be improved, and the soft synthetic resin can be provided by the support of the hard part. Deburring at the time of molding the resin portion becomes good, and post-processing after molding of the soft synthetic resin portion can be facilitated.

可能となる。In the case where a projection is provided at a position where the soft synthetic resin portion is disposed on the core metal of the ring portion and near the hard portion, the hard portion side of the soft synthetic resin portion corresponds to the hard portion. Even if an attempt is made to peel around the core bar so as to separate from the core, the protrusions become resistance, and it is possible to prevent the peeling.

を低減させることができる。Further, when an annular concave portion is provided on the outer periphery of the terminal of the support portion of the hard portion on the side of the soft synthetic resin portion, the soft synthetic resin portion enters the annular concave portion. Therefore, from the state where only the soft synthetic resin part is interposed around the core metal, the terminal side of the hard part side of the leather immediately approaches the annular groove of the hard part instead of being supported by the support part of the hard part. Accordingly, after being supported by the soft synthetic resin portion in the annular concave portion having a reduced thickness, the leather is supported by the support portion, so that the uncomfortable feeling of the leather can be reduced.
