    • A power transmission apparatus includes a pulley 1 having a belt attached thereto to transmit the rotating drive force, a hub 2 which connects the pulley to a rotating shaft of a driven device, a bearing 7 which rotatably supports the pulley, and a sleeve ring 5 which is fitted and secured to the pulley and attaches the bearing to the pulley to prevent it relatively moving. The sleeve ring is provided, on its first end opposite to the driven device, with a bent portion 5b against which the bearing abuts to restrict further movement of the bearing. An annular retainer 6 is provided on the portion of the bearing adjacent to the drive device. The bearing is secured to the sleeve ring through the annular retainer by calking a second end 5a of the sleeve ring opposite to the first end. The sleeve ring is provided with a projection 5f which projects in the axial direction from the rear surface of the pulley and a casing 9 is provided with an annular groove 9c which at least partly receives therein the projection.
    • 动力传递装置包括具有附接到其上以传递旋转驱动力的带的皮带轮1,将滑轮连接到从动装置的旋转轴的轮毂2,可旋转地支撑滑轮的轴承7和套筒环5 其被安装并固定到滑轮并将轴承附接到滑轮以防止其相对移动。 套筒环在其与被驱动装置相对的第一端处设置有弯曲部分5b,轴承抵靠着该部分5b以限制轴承的进一步移动。 环形保持器6设置在与驱动装置相邻的轴承部分上。 轴承通过将第一端部相对的套筒的第二端5a压紧而通过环形保持器固定到套筒环上。 套环设置有从滑轮的后表面沿轴向突出的突起5f,并且壳体9设置有至少部分地容纳有突起的环形槽9c。
