To provide a telescopic shaft and a steering device capable of securing large telescopic stroke without extending a fitting length between a male shaft and a female shaft.SOLUTION: A telescopic shaft has: a male shaft 15; a female shaft 16; and a plurality of rolling elements 17 arranged in a rollable manner between a male shaft side rolling surface provided in a first male shaft side groove 15a formed in the male shaft 15, and a female shaft side rolling surface provided in a first female shaft side groove 16a formed in the female shaft 16, where a distance from contact points B, B of the rolling element 17 to the male shaft side rolling surface to a rolling axis P of the rolling element 17 is different from a distance from a contact point A of the rolling element 17 to the female shaft side rolling surface to the rolling axis P.SELECTED DRAWING: Figure 2
【課題】雄軸と雌軸の嵌合長さを延長することなく大きな伸縮ストロークを確保した伸縮軸及びステアリング装置を提供する。【解決手段】雄軸15と、雌軸16と、雄軸15に形成された第1雄軸側溝15a内に設けられた雄軸側転動面と雌軸16に形成された第1雌軸側溝16a内に設けられた雌軸側転動面との間に転動自在に配置された複数の転動体17とを有し、転動体17の雄軸側転動面への接触点B、Bから転動体17の転動軸線Pまでの距離と、転動体17の雌軸側転動面への接触点Aから転動軸線Pまでの距離とが異なる。【選択図】図2
