Abstract
A steering wheel and steering wheel manufacturing method are provided in which misalignment of the relative position of the wood member and the metal core can be prevented or suppressed in the period until the elastic adhesive is cured. A wood member and a rim metal core portion are bonded by an elastic adhesive being present between the wood member and the rim metal core portion. Spacer members are disposed between the wood member and the rim metal core portion so as to position the wood member relative to the rim metal core portion. Consequently, misalignment of the relative position of the wood member and the rim metal core portion is suppressed by the spacer members during the period until the elastic adhesive is cured.
Claims16
A steering wheel comprising:
- a metal core that is fixed to a steering shaft of a vehicle;
- a wooden member that accommodates the metal core therein;
- an adhesive that is interposed between the wooden member and the metal core, and bonds the wooden member and the metal core;
- and
- spacer members that are disposed between the wooden member and the metal core, and
- positions the wooden member with respect to the metal core.
A manufacturing method of a steering wheel including:
- a metal core that is fixed to a steering shaft of a vehicle;
- a wooden member that accommodates the metal core therein;
- an adhesive that is interposed between the wooden member and the metal core and bonds the wooden member and the metal core;
- and spacer members that are disposed between the wooden member and the metal core, and position the wooden member with respect to the metal core, the wooden member being configured by a plurality of wooden pieces, and grooved portions configuring an internal face of the wooden member being respectively formed in the plurality of wooden pieces, the manufacturing method comprising:
- a spacer member attaching process in which the spacer members are attached to at least one of the metal core or to the grooved portion;
- a applying process in which the adhesive is applied in a pre-cured state thereof to at least one of the metal core or to the grooved portions;
- and
- an assembly process in which, after the spacer attaching process and the applying process, the plurality of wooden pieces are joined together so as to accommodate the metal core within the wooden member.
