[Detailed description of the device]

[0001]

[Industrial applications]

 The present invention relates to a steering wheel for an automobile, and more particularly, to a shock absorber disposed in a pad of a boss portion held by a clamp spring.

[0002]

[Prior art]

 Conventionally, in this type of steering wheel, as shown in FIGS. 4 and 5, a projection 05 for positioning and a screw hole 04 for attachment are provided on the lower surface portion 07 of the shock absorber, and the clamp spring 02 is screwed through. The hole 03 and the positioning hole 06 are provided, the positioning hole 06 is fitted to the positioning projection 05, the clamp spring 02 is positioned with respect to the shock absorber, and then the screw insertion hole 03 which is aligned with each other is attached. The clamp spring 02 was fixed to the lower surface portion 07 of the shock absorber by screwing the screw 01 into the screw hole 04 for use.

[0003]

[Problems to be solved by the device]

 However, according to the above-described conventional structure, when manufacturing the shock absorber, the positioning projections 05 are provided at predetermined positions on the lower surface portion 07 of the shock absorber in accordance with the desired mounting position of the clamp spring 02. Since it must be integrally formed, the manufacturing process becomes complicated, and shock absorbers with positioning projections that match each steering wheel model must be prepared. There was a problem of lacking.

Further, when the clamp spring is attached to the shock absorber, the work of fitting the positioning projections 05 and the positioning holes 06 to each other is considerably troublesome, so the work efficiency is inevitably reduced. .

The present invention has been made by paying attention to such a problem, and can position the clamp spring easily, and has a simple structure suitable for mass production and has versatility. The aim is to provide a steering wheel equipped with a shock absorber that is installed.

[0006]

[Means for Solving the Problems]

 In order to achieve the above-mentioned object, in the steering wheel of the present invention, a protrusion is provided on the lower surface of the shock absorber, and the guide surface of the clamp spring is brought into contact with the side surface of the protrusion so that the clamp spring Positioning is in progress.

[0007]

[Action]

 In the present invention, the protrusion is extended on the lower surface of the shock absorber, and the guide surface of the clamp spring is brought into contact with the side surface of the protrusion to position the clamp spring. Can be easily and changeably performed along the side surface of the ridge, increasing the work efficiency during assembly.

Further, since the ridges of the shock absorber can be easily integrally molded at the same time, the manufacturing process is simplified.

Further, since the mounting position of the clamp spring on the shock absorber can be arbitrarily changed along the ridge of the shock absorber, the shock absorber has versatility that can be adapted to various steering wheel shaping. It will be.

【Example】

 Embodiments of the present invention will be described below with reference to the drawings.

FIG. 1 shows a shock absorber 1 installed in a steering wheel of an automobile or the like. The shock absorber 1 is held via a clamp spring 2 on a boss plate fixed to a metal boss fitted to a steering shaft (not shown).

The shock absorber 1 is formed by extruding or casting a metal such as aluminum, or extruding or injecting a synthetic resin, and integrally formed, and has an opening 3 on the left and right, and an upper surface 4 and The lower surface portion 6 having the flange portion 5 has a planar shape, and the front and rear side surface portions 7 have a substantially cylindrical outer shape which is bent in a wave shape. When a shock is applied from above to the shock absorber 1 in the event of an automobile collision, the side surface portion 7 is mainly deformed to absorb the shock.

On each of the flange portions 5 of the lower surface portion 6 of the shock absorber 1, a pair of downwardly projecting ridges 8 are provided so as to extend over the entire length of the shock absorber 1. Therefore, as a result, the groove 9 is formed between each pair of protrusions 8. The width of the groove 9, that is, the interval between the protrusions 8 corresponds to the width of the mounting portion 10 of the clamp spring 2 fitted therein. In this case, the clamp spring 2 comes into contact with the side surface of the protrusion 8 with the side edge 11 acting as a guide surface.

When the clamp spring 2 is to be attached to such an impact absorber 1 in the arrangement as shown in FIG. 3, for example, the screw hole 12 is formed in the flange portion 5 in accordance with the arrangement. Just set it up. This is because the clamp spring 2 arranged in the groove 9 can be positioned at any position along the extension direction of the ridge 8, that is, can be prevented from rotating.

After that, the screw 14 is inserted into the screw insertion hole 13 provided in the mounting portion 10 of the clamp spring 2, and the screw 14 is screwed into the screw hole 12 of the flange portion 5 of the shock absorber 1. The attachment of the clamp spring 2 to the shock absorber 1 is completed.

Next, the operation of this embodiment will be described.

A pair of protrusions 8 are extended on each flange portion 5 of the lower surface portion 6 of the shock absorber 1, and a mounting portion 10 of the clamp spring 2 is fitted into a groove 9 between each pair of protrusions 8. Since the clamp spring 2 is positioned, that is, the rotation is stopped, the clamp spring 2 can be positioned easily and changeable along the extension direction of the ridge 8, and the work efficiency at the time of assembly is increased.

Further, since the protrusion 8 of each flange portion 5 of the shock absorber 1 extends over the entire length of the shock absorber 1, the shock absorber 1 is integrally formed by extruding a metal such as aluminum. In doing so, they can be easily formed at the same time, and since each ridge 8 also functions as a reinforcing member, the strength of the shock absorber 1 increases.

Further, the mounting position of the clamp spring 2 on the shock absorber 1 can be arbitrarily changed along each of the ridges 8. Therefore, such a shock absorber 1 can be used for forming various steering wheels. It will be adaptable and versatile.

Further, since the side surface 11 of the clamp spring 2 also serves as the guide surface of the clamp spring 2 that comes into contact with the side surface of the ridge 8, it is not necessary to additionally provide a guide surface, and the clamp spring is not required. Making 2 is easy.

The structure of the shock absorber of the present invention is not limited to the above embodiment, and various modifications can be made within the scope obvious to those skilled in the art. For example, the ridges may be provided not as a pair but individually and the ridges may contact only one guide surface of the clamp spring, or conversely, three or more ridges may simultaneously contact the one clamp spring. You can also

[Effect of device]

 As described above, according to the present invention, the protrusion is extended on the lower surface of the shock absorber, and the guide surface of the clamp spring is brought into contact with the side surface of the protrusion to position the clamp spring. Therefore, the positioning of the clamp spring is easily and changeable along the side surface of the ridge, and the work efficiency at the time of assembly is increased.

Further, since such a ridge can be easily formed at the same time when the shock absorber is integrally molded, the work efficiency at the time of manufacturing the shock absorber is improved in mass production, and thus the shock absorber is improved. The cost of manufacturing the body can be reduced.

Moreover, since such a ridge effectively functions as a reinforcing member, the ridge increases the strength of the shock absorber.

Further, since the mounting position of the clamp spring on the shock absorber can be arbitrarily changed along the ridge of the shock absorber, the shock absorber has versatility that can be adapted to various steering wheel shaping. It will be.
