PROBLEM TO BE SOLVED: To provide a telescopic shaft having a high buffer effect.SOLUTION: A telescopic shaft 1 includes an inner shaft 10, an outer shaft 20, a plurality of rolling bodies 30 arranged between recess grooves 11, 21 of the inner shaft 10 and outer shaft 20 and aligned in an axial direction X, a stopper 41, and a buffer 51. The stopper 41 prevents the rolling bodies 30 from falling from the recess groove 11 of the inner shaft 10. The buffer 51 is interposed between the stopper 41 and a rolling body 30e at the end part of a row. The end surface of the buffer 51 contains an inclined contact part 51b inclined to a shaft right-angle surface P of the inner shaft 10. In stroke end of the inner shaft 10 to the outer shaft 20, the contact part 51b contacts with the rolling body 30e at the end part of the row.SELECTED DRAWING: Figure 1

    【課題】緩衝効果の高い伸縮軸を提供する。【解決手段】伸縮軸1は、内軸10と、外軸20と、内軸10および外軸20の凹溝11,21間に配置されて軸方向Xに並ぶ列をなす複数の転動体30と、ストッパ41と、緩衝体51とを備える。ストッパ41は、転動体30が内軸10の凹溝11から脱落することを規制する。緩衝体51は、ストッパ41と列の端部の転動体30eとの間に介在する。緩衝体51の端面は、内軸10の軸直角面Pに対して傾斜する傾斜状の当接部51bを含む。外軸20に対する内軸10のストロークエンドにおいて、当接部51bが、列の端部の転動体30eと当接する。【選択図】図1
