2. Description of the Related Art Conventionally, a steering wheel shown in FIG. 1 has a plurality of horn switches disposed between a steering wheel body and a horn pad disposed above a center of the steering wheel body. It has been known (see Japanese Patent Application Laid-Open No. 5-139318).

In the steering wheel W0, the horn switch body 3 between the steering wheel main body 1 and the horn pad 2 is composed of a horn spring 4, insulating spacers 5.6, rivets 7, and a base plate 8.

The horn spring 4 has an insulating spacer 5.
6 and the base plate 8 with rivets 7
And urges the horn pad 2 upward, and is electrically connected to the positive electrode side of the horn operation circuit via the rivet 7 described above. The base plate 8 constitutes the upper part of the sheet metal impact energy absorber E, and is electrically connected to the negative electrode side of the horn operation circuit via the metal core 1a on the steering wheel body 1 side. .

[0005] 9 is a screw 1 from below the base plate 8.
0 is a guide spacer attached to the lower surface side of the horn pad 2. The guide spacer 9 guides the downward movement of the horn pad 2 when the horn operates,
Further, the horn pad 2 is prevented from coming off the base plate 8.

Reference numeral 11 denotes a screw 1 on the lower surface of the base plate 8.
The mounting piece 11 is inserted and locked in a locking hole 1b provided in the steering wheel main body 1, and the horn switch body 3 mounted on the base plate 8 is mounted together with the horn pad 2. , Attached to the steering wheel body 1 side.

[0007]

However, in the conventional steering wheel W0, since the horn switch body 3 is arranged on the upper surface of the impact energy absorber E, even if the impact force has a low load value, the impact energy can be reduced. Absorber E
Plastically deforms and absorbs its energy,
In the case where the impact energy absorber E is configured to have a reduced thickness by making the sheet metal thin or the like, when the horn pad 2 is pressed down during normal horn operation, the impact energy absorber E
Is deformed, and the horn switch body 3 is made to be in a state of normal sound or no sound, which is not preferable.

In order to cope with this problem, it is conceivable to displace the horn switch body from above the impact energy absorber, and in such a case, the member supporting the horn switch body or the horn switch body itself is considered. However, it interferes with the impact force when the impact force is applied, and cannot effectively absorb the energy of the impact force.

The present invention has been made to solve the above-mentioned problem, and provides a steering wheel capable of minimizing interference of a horn switch body and a support member thereof against an impact force acting on the center of a horn pad. With the goal.

[0010]

[0011] bottom wall portion of the supporting bracket, to form a mounting hole for mounting the impact energy absorber, the bottom wall portion itself in order to facilitate plastic deformation, it is desirable to form a hole.

[0012]

In the steering wheel according to the present invention, each horn switch body is attached and fixed to an inner portion of a support base for supporting an outer portion on each spoke portion coating layer. Because the arrangement site is far away from the central portion of the horn pad as the back side portion of the extended portion on the outer peripheral edge of the horn pad,
Even when an impact force acts on the center of the horn pad, each horn switch body hardly interferes with the impact force.

[0013] Also, in the sheet metal support bracket supporting each horn switch body, the bottom wall between the arms is arranged as a concave shape so that an impact force acts on the center of the horn pad. Even hard to interfere.

If an impact force acts on the center of the horn pad, even if it interferes with each horn switch body, the inner part of each support base of the support bracket to which each horn switch body is mounted and fixed is fixed. , Floating from the steering wheel body and supported by the upper end of each arm of the support bracket, it has a cantilever shape, and is easily bent downward,
Each horn switch body together with the inner part of each support base,
By bending downward, interference of the horn switch body and the support bracket can be prevented as much as possible.

When the horn pad is pressed down, the projecting piece of the horn pad pushes the upper end of the horn spring of each horn switch body which extends obliquely upward.
Although the Rukoto contacting the contacts each other pressed, the contacts of the horn switch bodies, since it is located outside the site of the support portion which is supported on the spoke portion covering layer are stably supported, horn operating Can be prevented from causing deformation.

Therefore, in the steering wheel according to the present invention, the interference of the horn switch body and the supporting members thereof can be suppressed as much as possible with respect to the impact force acting on the center of the horn pad. There is no hindrance to the push-down operation.

A mounting hole for mounting an impact energy absorber is formed in the bottom wall of the support bracket, and when a hole is formed such that the bottom wall itself is easily plastically deformed , the bottom wall is formed. If the impact energy absorber is attached to the part using the mounting hole, the bottom wall itself has a predetermined hole and easily deforms when an impact force is applied. The energy of the impact force can be absorbed by the deformation, so that even if the impact force of a wide range of load values acts, it is easy to cope with it.
