ABSTRACT:
A telescopic assembly includes a yoke supported for rotation on a stationary member, a shaft fitted in telescoping relation inside the yoke, rotatably supported by a movable bracket and capable of being reciprocated together with the movable bracket relative to the yoke, a screw rotatably retained by a stationary bracket, and a nut threadedly engaged with the screw and fixed to the movable bracket. When the screw is rotated, the nut provided on the movable bracket moves axially along the screw so that the movable bracket is moved toward or away from the stationary bracket. Hence, the shaft supported by the movable bracket is displaced axially forward or backward, depending upon the direction of screw rotation, relative to the yoke, thereby enabling the portion of the shaft projecting from the yoke to be adjusted in length.
