Claims

[Scope of utility model registration request]

A power transmission belt wound between an output pulley and an input pulley, a tension roller supported by a movable support and capable of moving toward and away from the belt, and a tension roller connected to the support through a wire. In a tension clutch operating device having a clutch lever that is connected to the clutch lever and can freely rotate back and forth and is biased toward a neutral position by a biasing body, rotation of the clutch lever causes the tension roller to be attached to the belt. The present invention is characterized by being provided with a locking mechanism that locks the clutch lever at the tension applying position where the clutch lever is brought into contact, and releases the locked state of the clutch lever by rotating the clutch lever in the locked state again in the same direction. Tension clutch operating device.
