    Abstract: A telescopic shaft (1) includes: an inner shaft (10) where a pair of recessed grooves (11) that face each other in a direction (R) perpendicular to an axis and extend in an axial direction (X) are formed; an outer shaft (20) where a pair of recessed grooves (21) that face each other in the direction (R) perpendicular to the axis and extend in the axial direction (X) are formed; a plurality of rolling bodies (30) that are disposed between each of the recessed grooves (11) and the corresponding recessed groove (21) so as to form a line in the axial direction (X); a pair of stoppers (41); and a buffer body unit (50). Each of the stoppers (41) restricts falling of a rolling body (30e) at an end portion of the corresponding line from the corresponding recessed groove (11) of the inner shaft (10). The buffer body unit (50) integrally includes a pair of buffer bodies (51), and a connection portion (52) that connects the pair of buffer bodies (51).

    Abstract translation: 本发明提供一种伸缩轴（1），其包括：内轴（10），其形成有在与轴垂直的方向（R）上相对且沿轴向（X）延伸的一对凹槽（11） 外轴（20），其形成有在与轴垂直的方向（R）上相对的一对凹槽（21），并沿轴向（X）延伸; 多个滚动体（30），所述多个滚动体（30）以在所述轴向（X）上形成直线的方式配置在各所述凹槽（11）与所述凹槽（21）之间。 一对挡块（41）; 和缓冲体单元（50）。 每个止动件41限制相应线的端部处的滚动体30e从内轴10的对应凹槽11中掉落。 缓冲体单元50一体地包括一对缓冲体51和连接一对缓冲体51的连接部52。

    Abstract: A telescopic shaft (1) includes an inner shaft (10), an outer shaft (20), a plurality of rolling bodies (30) that are disposed between recessed grooves (11, 21) of the inner shaft (10) and the outer shaft (20) and form a line in an axial direction (X), a stopper (41), and a buffer body (51). The stopper (41) restricts falling of the rolling bodies (30) from the recessed groove (11) of the inner shaft (10). The buffer body (51) is interposed between the stopper (41) and a rolling body (30e) at an end portion of the line. An end surface of the buffer body (51) includes an inclined abutment portion (51b) that is inclined with respect to a plane (P) perpendicular to an axis of the inner shaft (10). The abutment portion (51b) abuts against the rolling body (30e) at the end portion of the line at a stroke end of the inner shaft (10) with respect to the outer shaft (20).

    Abstract translation: 本发明提供一种伸缩轴（1），其包括内轴（10），外轴（20），配置在内轴（10）的凹槽（11,21）与外轴 （20）并且在轴向方向（X）上形成一条直线，一个止动件（41）和一个缓冲体（51）。 止动件41限制滚动体30从内轴10的凹槽11中脱落。 缓冲体（51）介于止动件（41）与线的端部的滚动体（30e）之间。 缓冲体51的端面具有相对于与内轴10的轴线垂直的平面P倾斜的倾斜抵接部51b。 抵接部（51b）在内轴（10）的行程末端相对于外轴（20）的线端部与滚动体（30e）抵接。
