Description

[Detailed description of the invention] This invention relates to a steering wheel in which the structure of the outer rim metal shaft of the steering wheel f of a vehicle, etc. is generally improved.
Appropriately, a plurality of small diameter metal tubes 3.3 are bundled in a ring shape around the outer periphery of a metal spoke 2 having a metal shaft tube 1 connected to the center core, and the bonded surfaces of the metal spokes 2 are connected to each other. Welded together with solder 4,
The outer rim metal shaft 5 is integrally welded with solders 6, 6..., and the outer rim metal shaft 5 is coated with a thick inner coating layer γ of synthetic resin or rubber, etc. It is buried within the
As an embodiment thereof, the outer rim metal shaft 5 is as follows:
Two or three circular small-diameter steel pipes 3, 3... are used, and the opposing bonding surfaces of the circular small-diameter steel pipes 3, 3... are mutually solder welded 4°4... ..., and as the outer rim metal shaft 5, two circular small diameter steel pipes 3', 3' having a flat surface 8 on the outer side are used, and these circular small diameter steel pipes 3', The flat surfaces 8, 8 of 3' are in contact with each other, and the opposing surfaces are welded together with solder 4', 4', or the outer rim metal shaft 5 may have a flat surface 8 on the outside, respectively.
Three circular small-diameter steel pipes 3'13'e3/ are used, and the flat surfaces 8,
8.8 are faced to each other, and their facing surfaces are solder welded to each other 4', 4
', 4', which reduces the weight of the product without impairing the strength of the outer rim metal shaft, facilitates the molding process, and has an adhesive bent portion 10 on the outer rim. Therefore, the purpose is to eliminate the need for peeling off the coating layer provided on the outer peripheral surface and processing the locking engagement structure, reducing the number of processing steps, and thereby simplifying the equipment. It is something that makes you

In the drawings, reference numeral 9 indicates a shaft hole, and reference numeral 10 indicates an adhesive bent portion.

Conventionally, an outer rim metal shaft 5 in this type of steering handle has been used.
/ is the diameter of 127a to 181g as shown in Figure 6.
It was constructed from a solid steel material consisting of about 1 piece of steel wire or steel rod.

Therefore, in the case of a steering wheel E having a droplet diameter of 400w11 to 50011m, the product weight increases, which is not in line with recent efforts to reduce the weight of vehicles.

In addition, since it is a solid steel material, not only is it difficult to form it into a ring shape, but when providing the coating layer γ, the outer peripheral surface f has a locking structure such as an uneven shape due to the rotation prevention during grasping operation. In addition to requiring many man-hours to process, there is a risk that the equipment for these processes may become complicated.

This invention improves this conventional structure and eliminates its drawbacks.According to this invention, the center core l, the metal shaft cylinder
A plurality of small-diameter metal tubes 3, 3, . 4... The outer rim metal shaft 5 is integrally welded with solder 6°6...
Since the outer rim metal shaft 5 is embedded within the thick coating layer 1 of synthetic resin or rubber, the outer rim metal shaft 5 can be made of two or three circular small diameter steel pipes 3. ，
3... are used, and these circular small diameter steel pipes 3, 3
The opposing adhesion surfaces of ...... are mutually soldered welded 4, 4...
...It is very useful to be able to do so.
