In the present invention, a stopper member (5) constituting a stopper portion that restricts movement in a direction in which a rotating shaft (31) of a transmission (3) and a shaft portion (41) of a first drive-side joint member (J11) approach each other is provided independently from the shaft portion (41) and a yoke body portion (42). The stopper function of the first drive-side joint member (J11) is secured by a stopper member (5) provided separately from the first drive-side joint member (J11). Therefore, the change of the center-of-gravity position of the first drive-side joint member (J11) due to build-up welding of the shaft section (41) or the yoke body section (42) is suppressed, and the relative movement between the first drive-side joint member (J11) and the rotating shaft (31) can be restricted while ensuring appropriate machining of the shaft section-side seal surface (412).
本发明中,构成限制变速装置(3)的旋转轴(31)与第一驱动侧接头部件(J11)的轴部(41)相互接近的方向的移动的限位器部的限位器部件(5)与轴部(41)以及节叉主体部(42)独立设置,第一驱动侧接头部件(J11)的限位器功能通过与第一驱动侧接头部件(J11)独立设置的限位器部件(5)确保。因此,抑制由于对轴部(41)或者节叉主体部(42)进行堆焊导致的第一驱动侧接头部件(J11)的重心位置的变化,既能够确保轴部侧密封面(412)的适当的机械加工,又能够限制第一驱动侧接头部件(J11)与旋转轴(31)的相对移动。
