Document Type and Number:
WIPO Patent Application WO/2012/011692
Kind Code:
A2
Abstract:
Provided is a variable device for varying the central axis of a wheel, which simplifies a configuration of the variable device to thereby reduce a production cost and which controls an eccentricity position of the wheel conveniently and accurately step by step. The central axis variable device include: a rotating body along the inner circumference of which a first uneven portion is formed and both sides of which are pierced with respect to each other; a first cap that is combined at one side of the rotating body, and on the eccentric portion of which an eccentricity hole and a thread-coupling hole are formed; a second cap along the outer circumference of which a second uneven portion is formed in correspondence to the first uneven portion to thus be combined at the other side of the rotating body, and on which a shaft tube that is inserted into the eccentricity hole and an engagement hole corresponding to the coupling hole are formed; a coupling member that passes through the coupling hole and the engagement hole and couples the first and second caps with each other; a step groove that is stepped toward the engagement hole and that is formed at the side of the second cap; and an interference protrusion that has an elastic force to come in and out toward the step groove and is formed in the inner side of the second cap, in which the coupling member comprises a head portion on which a plurality of grooves are formed so that the interference protrusion is arranged into one of the plurality of grooves, and a thread portion that is thread-coupled with the coupling hole of the first cap.
