(101, 102) can be induced to be accurately coupled, there is an effect that misassembly is prevented and the assembly defect rate is remarkably lowered. In addition, the first and second substrate units 610 and 660 have an effect of simplifying the number of parts by a shared design.

11 is a cross-sectional view showing a state in which a cover of a rotary ring for a vehicle according to a preferred embodiment of the present invention is coupled to a housing.

Referring to FIG. 11 , the cover 700 is formed to cover the outer periphery of the housing 100 . Both sides of the cover 700 are formed to be coupled to a vehicle. In addition, an O-ring 710 is fitted to the outer periphery of the housing 100, and the O-ring 710 is configured to be in close contact with the inner periphery of the cover 700. Accordingly, vibration transmitted to the cover 700 during vehicle operation is absorbed by the O-ring 710, and vibration caused by the vehicle is not transmitted to the housing 100, thereby preventing noise generation between products.

Although the present invention has been described in detail in the above embodiments, it is obvious that the present invention is not limited thereto, and various changes and modifications are possible within the scope of the technical idea of the present invention. If it falls within the scope of the claims, the technical idea should also be regarded as belonging to the present invention.
