PROBLEM TO BE SOLVED: To provide a telescopic shaft having excellent assemblability.SOLUTION: A telescopic shaft 1 includes: an inner shaft 10 forming a pair of recess grooves 11 opposite to a shaft right-angle direction R and extending in an axial direction X; an outer shaft 20 forming a pair of recess grooves 21 opposite to the shaft right-angle direction R and extending in the axial direction X; a plurality of rolling bodies 30 arranged between corresponding recess grooves 11, 21 and aligned in the axial direction X; a pair of stoppers 41; and a buffer unit 50. Each stopper 41 prevents a rolling body 30e at the end part of a corresponding row from falling from a corresponding recess groove 11 of the inner shaft 10. The buffer unit 50 integrally contains a pair of buffers 51 and a connection part 52 connecting between the pair of buffers 51.SELECTED DRAWING: Figure 1

    【課題】組立性の良い伸縮軸を提供する。【解決手段】伸縮軸1は、軸直角方向Rに対向し軸方向Xに延びる一対の凹溝11を形成する内軸10と、軸直角方向Rに対向し軸方向Xに延びる一対の凹溝21を形成する外軸20と、対応する凹溝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、一対のストッパ41と、緩衝体ユニット50とを備える。各ストッパ41は、対応する列の端部の転動体30eが内軸10の対応する凹溝11から脱落することを規制する。緩衝体ユニット50は、一対の緩衝体51と一対の緩衝体51間を連結する連結部52とを一体に含む。【選択図】図1
