シヨン装置。 A tension arm, to which a pressing part for pressing a transmission belt, etc. of a clutch device is attached, is rotatably supported around a support shaft, while a support shaft is located on the opposite side of the pressing part with this support shaft in between. The intermediate arm that rotates around the periphery is provided with an engaging portion that engages with the arcuate guide portion of the tension arm so as to be slidable along its longitudinal direction, and the engaging portion and the support shaft are connected to each other. When the intermediate arm is rotated in the direction in which the pressing part presses against the transmission belt, etc. and in the direction in which the pressing part moves away from the transmission belt, etc., the intermediate arm is rotated in each direction beyond the support shaft for the tension arm. A tension device characterized by being equipped with a biasing spring that crosses a fulcrum.
