Abstract
A hollow cylindrical pulley bodyis carried rotatably by a hollow cylindrical shaft member. A support rodis inserted in the shaft memberto support the shaft memberfor rocking motion about a pivot axis Corthogonal to the shaft member. The pivot axis Cis inclined backward in the direction of belt travel with respect to the direction of load on the shaft member. 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 load on the shaft memberand is positioned obliquely relative to the drive belt, thereby producing a force of returning the drive beltto its normal position.
