Claims

[Scope of utility model registration request]

A belt is loosely wound between two pulleys of different diameters on the driving shaft and two pulleys of different diameters on the driven shaft, and a tension arm whose base end is pivotally connected is attached to each belt. The trochanter at the tip of both tension arms is placed in contact with the outer circumferential surface of each belt, and the tension arm is provided with a mechanism for rotating one or both of the tension arms in a direction away from the belt. while connecting operating means for
Both tension arms are each provided with a spring that biases each belt in the direction of tension, and one end of each spring is engaged with each end of a balance lever whose center portion is rotatably pivoted. gearbox.
