Abstract
A hollow cylindrical pulley bodyis carried rotatably by a hollow cylindrical shaft member. A support rodis inserted in the shaft member, and the shaft memberis elastically supported to the support rodthrough an elastic body. The elastic bodyis provided within a quarter of the periphery of the support rodthat is located, when viewed along the axis of the shaft member, forward of the line of action of a radial shaft load on the shaft memberwith respect to the direction of rotation of the pulley body. With this configuration, when the drive beltdeviates to one side, the pulley bodyis immediately angularly moved so that it is inclined with a level difference with respect to the direction of the radial shaft load and is positioned obliquely relative to the drive belt. In this manner, a force of compensating for the deviation of the drive beltis produced to avoid its wobbling.
