Patent ID: 7290678

Claim:
A cup holder for a vehicle having a container insertion member for accommodating a beverage container therein, said cup holder comprising: a rotation bushing installed in such a manner that said rotation bushing encompasses an outer surface of a rotary shaft on a surrounding portion of the container insertion member, and compresses or decompresses the outer surface of the rotary shaft, so that rotation on the rotary shaft is selectively limited; a support member installed in an upper side of the rotation bushing and having a curved surface closely contacting an outer surface of a beverage container accommodated in the container insertion member when the support member is rotated with respect to the rotary shaft together with the rotation bushing; and button means installed in the support member, in such a manner that the rotation bushing and the support member are rotated together, and connected with the rotation bushing through a locking part, so that the locking part compresses or decompresses the rotation bushing; wherein said rotation bushing includes a cylindrical elastic compression part encompassing the outer surface of the rotary shaft and outwardly elongated open ends separated from each other with a predetermined gap, wherein said rotation bushing compresses or decompress the outer surface of the rotary shaft by adjusting the gap between the elongated open ends in response to the locking part of the button means; and wherein said button means is installed in an engaging hole of the support member and comprises two parallel locking parts elongated downwardly from a lower surface thereof, wherein the locking parts are operatively connected with the rotation bushing in such a manner that front ends of the two locking parts are inserted into a groove formed on outer surfaces of the elongated open ends of the rotating bushing, and slanted surfaces formed on inner surfaces of the front ends of the two locking parts slide on wedge-shaped slanted surfaces formed on the outer surfaces of the elongated open ends of the rotating bushing, so that the rotation bushing compresses or decompress the outer surface of the rotary shaft by adjusting the gap between the elongated open ends in response to the locking part of the button means.
