Abstract

A steering wheel of the present invention is provided with: a spoke cored bar portion configured to couple a boss cored bar portion and a rim cored bar portion to each other. At least a surface of a respective one of the rim cored bar portion and the spoke cored bar portion is covered with a synthetic resin. An inclined longitudinal wall portion is coupled to the spoke cored bar portion at a connection portion, and at an intermediate part of the connection portion, an easily deformable portion is formed. In this manner, it is possible to provide a steering wheel which is not degraded in appearance quality, even if a rib for preventing shrinkage of a resin is increased in size, the steering wheel having an excellent dynamic performance thereof.

First claim

What is claimed is:

1. A steering wheel comprising:
a boss cored bar portion;
a rim cored bar portion; and
a spoke cored bar portion configured to couple the boss cored bar portion and the rim cored bar portion to each other, at least a surface of a respective one of the rim cored bar portion and the spoke cored bar portion being covered with a synthetic resin,
wherein an inclined wall portion is coupled to a connection portion which connects directly to the spoke cored bar portion, the inclined wall portion extending longitudinally along the spoke cored bar portion,
wherein the connection part has a plurality of parts arranged in a longitudinal direction, a thickness of the connection portion being at a minimum at an intermediate part among the plurality of parts, and
wherein the connection portion has a groove thereon which determines the thickness of the connection portion at each of the plurality of parts.

2. The steering wheel according to claim 1 , wherein the thickness of the connection portion at the intermediate part may be deformed by an external pressure is applied in a direction substantially parallel to the spoke cored bar portion.

3. The steering wheel according to claim 1 , wherein the intermediate part comprises a plurality of through holes.

4. The steering wheel according to claim 1 , wherein a notch is formed in the intermediate part.
