发明名称 Telescopic shaft
摘要 This invention provides a telescopic shaft in which a backlash or a sliding resistance in a rotational direction is maintained to a predetermined value even when there are fabrication errors in a male shaft and a female shaft, and a preload is not reduced even when a sleeve is worn by a friction force in sliding, and a steering apparatus having the telescopic shaft. An inclined sleeve portion 712 is pressed by an elastic deformation of an urge sleeve portion 713, so that there is not backlash between a male shaft 12B and a female shaft 12A and a predetermined preload is applied. Although an outer periphery of the inclined sleeve portion 712 is worn by a friction in sliding, the inclined sleeve portion 712 is further pressed by an elastic force of the urge sleeve portion 713 by an amount of wearing the outer periphery of the inclined sleeve portion 712. Thus, a predetermined urge force is always operated to the inclined sleeve portion 71.
