IPC: B60R21/215
Filed: 1999-11-08
Abstract: PROBLEM TO BE SOLVED: To provide a mark member fixing structure of a steering wheel that can strongly fix a mark member to a pad cover and reduce cost. SOLUTION: In the steering wheel 10, the tip of a fixing leg 28 is butted on a tapered portion 18 adjacent to a fixing hole 16 by folding the fixing leg 28 in a state in which the fixing leg 28 of the mark member 24 is inserted into the fixing hole 16 of the pad cover 14. Because the tapered portion 18 has a triangular cross section, the fixing leg 28 is folded at an acute angle, a bent portion 28A of the fixing leg 28 abuts on the corner portion 18A of the tapered portion 18, the tip of the fixing leg 28 is caught by the tapered portion 18 at a strong force, the folded state of the fixing leg 28 is hardly released, and therefore the mark member 24 can strongly fixed to the pad cover 14. Additionally, an additional component such as a conventional pin is not required to reduce the number of components, and the cost can be reduced.
