本考案は、自動車等のステアリングホイール装
置に係り、特に、そのボス部の下側に導電用のス
リツプリングを取付ける構造に関するものであ
る。[Detailed Description of the Invention] [Purpose of the Invention] (Field of Industrial Application) The present invention relates to a steering wheel device for an automobile, etc., and particularly relates to a structure in which a conductive slip ring is attached to the lower side of the boss portion of the steering wheel device. It is something.

しめて固定する場合もある。(Conventional technology) In the steering wheel of automobiles, etc.,
A conductive slip ring is attached to the underside of the synthetic resin boss cover at the boss part.
In this case, as a general method, for example,
As shown in Japanese Patent No. 59-25140, the slip ring is fixed with screws. In some cases, a part of the synthetic resin boss cover is crimped and fixed to the slip ring.

リツプリングが脱落するおそれもある。 However, when attaching the slip ring to the lower side of the boss using screws, tightening the screws is troublesome, and if the tightening force of the screw is too strong, the contact piece fixed to the power receiving surface of the slip ring, that is, the steering column, may be damaged. The sliding surface may be deformed. In addition, when attaching a slip ring to the lower side of the boss part by caulking, the power receiving surface of the slip ring is easily deformed during caulking, as is the case with screw tightening, and its holding force is weak.
Since the boss cover is made of synthetic resin and is easily deformed by heat, there is a risk that the slip ring may fall off.

底面部の上面側に係止するものが知られている。 Furthermore, as shown in Japanese Utility Model Application Publication No. 57-192870, a slip ring is conventionally formed of a conductive synthetic resin, and a plurality of inwardly facing locking claws are integrally provided on the inner circumference of the slip ring. It is known that these locking claws are locked to the top side of the bottom surface of the boss cover through through holes formed in the bottom surface of the boss cover.

ことがある。 However, in this device, the slip ring and each of the locking claws must be molded from conductive synthetic resin, and since the locking claws protrude from the slip ring and face inward, the synthetic resin If the boss cover made of aluminum shrinks due to temperature changes, the amount of locking of the locking pawl will decrease, which may cause looseness.

According to the present invention, each of the locking portions of the boss cover has a substantially downward U-shaped cross section and has a large amount of elastic deflection, so that the locking pawl and the locking hole in the engagement piece of the slip ring can easily be connected to each other. The slip ring is extremely easy to assemble and does not deform the sliding surface of the slip ring, and the locking pawl of the locking part is designed so that elasticity acts inward even after it is locked in the locking hole. Since it is located on the outside of the engagement piece, there is always an elastic force that tries to return it to its original position, so even if the synthetic resin in the boss cover deforms over time or shrinks due to temperature changes, it will not work. The locking hole of the slip ring remains locked to the locking pawl and does not come off. Therefore, for example, if the ambient temperature changes and the temperature becomes high, then the driver drives the car. The diameter of the slip ring fitting part contracts when the temperature reaches room temperature, but since the engagement piece of the slip ring is locked to the locking part at the outer position, the engagement does not occur in the direction of contraction. It is strong and can be held securely without rattling when running.
