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.

Steering wheel and manufacturing method of steering wheel

A steering wheel structure, comprising: an internal member provided inside a vehicle steering wheel; a covering member, adhered to a surface of the internal member and covering the internal member; a first concave-convex portion, provided at the surface of the internal member and disposed in a predetermined pattern thereon; and a second concave-convex portion, provided at surfaces of the first concave-convex portion, is provided.

Steering wheel structure

A steering wheel having partially applied wooden outer covers, which can be produced without having the wooden outer covers scratched, and the like, and can be produced with high working efficiency, and a method for manufacturing the steering wheel are provided. Raw materials, from which wood members are formed, are attached at a rim portion of a core metal, and cores are formed in this state. Thereafter, the wood members are shaped from the raw materials. Further, resin pieces are attached in spaces between the wood members and the cores to limit displacement of the wood members. Then, the cores and the resin pieces are covered with covering portions. As described above, spaces are formed, and the cores are formed in a state in which the raw materials of the wood members are attached. This allows shaping of the wood members after formation of the cores. Since the wood members can be shaped after the cores are formed, even if the wood members are scratched while the cores are formed, the scratches can be removed when the wood members are shaped.

Steering wheel and method for manufacturing steering wheel

An air bag cover holding structure comprises: a plate-shaped bag holder for fixing an air bag cover to a steering wheel, the plate-shaped bag holder having engaging claws which are respectively engaged with hook-shaped grooves formed on an inner peripheral wall at an open-side end of the air bag cover; a reinforcing plate fixed in a state of overlapping with the plate-shaped bag holder and having engaging portions, the engaging portions being respectively inserted in plate inserting holes which are formed at the open-side end of the air bag cover in directions crossing the hook-shaped grooves so as to hold the air bag cover together with the engaging claws; and a pull-out prevention reinforcing member provided in at least one of the engaging claws and the engaging portions to prevent the air bag cover from being pulled out from the plate-shaped bag holder and the reinforcing plate.
