Description of the Related Art A rotary connector is generally composed of a pair of housings which are coaxially and relatively rotatably connected to each other, and a strip-shaped flexible cable which is wound in an annular housing portion formed by the both housings. Both ends of the flexible cable are fixed to respective housings and then led out to the outside.

撓性ケーブルは外筒部側に巻き戻される。Such a rotary connector is incorporated in a steering device of an automobile, one housing is attached to a steering column or the like and is used as a fixed body, and the other housing is attached to a handle side and is used as a movable body. In use, when the movable-side housing is rotated forward or backward in conjunction with the operation of the handle, the flexible cable is wound around the inner cylinder portion inside the storage portion, and the housing is moved to the other side. When rotated to, the flexible cable is rewound to the outer cylinder side.

回転コネクタが提案されている。By the way, in the rotary connector having such a general structure, since the movable side housing is rotatably connected to the fixed side housing, a sliding noise is generated from a portion where both housings are in sliding contact with each other. Was generated, which was annoying noise. Therefore, from the past, the actual development 6
As disclosed in JP-A-4-22558, a rotary connector has been proposed in which a sliding ring is provided in a sliding portion of both housings, and the sliding sound is reduced by the sliding ring. ing.

く、騒音の低減効果がなくなるという問題があった。However, in the conventional rotary connector disclosed in the above publication, if the dimensions of the sliding ring are not strictly controlled, a clearance will be created between the sliding ring and the housing. However, there has been a problem that both housings rattle and an abnormal noise is generated, or the sliding ring cannot be incorporated in the sliding portion. Even if the sliding ring could be tightly incorporated in the sliding portion, a clearance may be created between the sliding ring and the housing due to environmental temperature changes. However, there is a problem in that, when the two are molded from different synthetic resins, a clearance is easily formed between the sliding ring and the housing due to the difference in thermal expansion coefficient between the two, and the noise reduction effect is lost.

特性が高められる。In the above structure, when a convex portion is formed on the peripheral surface of the sliding ring and the convex portion is elastically contacted with either one of the first housing and the second housing, the protrusion from the convex portion is removed. The peripheral surface of the sliding ring is pressed against the other housing by the force, so that the sliding ring can be tightly provided in the annular gap. Further, when a convex portion is formed on the peripheral surface of the sliding ring and the convex portion is locked in a concave portion formed in either the first housing or the second housing, the side of the convex portion is locked. Since the housing and the sliding ring are integrated, the degree of freedom in selecting the materials for both is increased. Further, the sliding ring is fixed to either one of the two housings and slidably contacts the other housing, and the sliding ring and the housing on the side slidingly contacting the sliding ring are made of different synthetic resins. By molding with, it is possible to prevent fusion between materials on the sliding surface and galling, so that sliding characteristics are improved.

Respectively slide on the inner peripheral surface of the center hole 12. Therefore,
The second housing 2 rotates with respect to the first housing 1 by using the sliding rings 5 and 6 as a rotary sliding portion, and the sliding rings 5 and 6 and the first housing 1 slide with each other by different kinds of materials, so that they rotate. The sliding noise at that time is greatly reduced. Also,
Even if the diameter of the annular gap between the center holes 11 and 12 and the second housing 2 changes due to changes in the environmental temperature,
This fluctuation is absorbed by the bending of the cylindrical portions 5a and 6a of the sliding rings 5 and 6, so that the sliding rings 5 and 6 do not rattle, and rattling noise and sliding noise are generated for a long period of time. It can be reduced. Furthermore, since the sliding rings 5 and 6 rotate integrally with the second housing 2 and sliding friction does not occur between them, the sliding rings 5 and 6 and the second
The housing 2 may be made of a different material or the same material,
The degree of freedom in selecting the material can be increased.

When set to 2 , W 1 > W 2 is set in the unloaded state before the sliding ring 15 is incorporated in the rotary connector. Then, the sliding ring 15 and the center hole 11 and the upper paragraph 2
When it is provided in the annular gap between a, the frame portion 15b elastically deforms outwardly and comes into close contact with the peripheral surface of the paragraph portion 2a, and the tubular portion 15a elastically deforms inwardly so that the inside of the center hole 11 can be prevented. It comes into close contact with the peripheral surface and W 1 = W 2 . Also in this case, the sliding ring 15
Since there is a possibility of sliding with respect to both housings 1 and 2, the sliding ring 15 and both housings 1 and 2 must be made of different materials.
