えることはできなかつた。 In this way, in the conventional device, the elastic force in the direction of the coil center line of the tension coil spring is used to give the initial tension. Since the pressure contact mechanism of the tension wheel 5 is formed by using, for example, a large number of parts, there are many assembly steps, especially for a device for an automobile internal combustion engine that is desired to be small and compact, which causes various inconveniences in improving workability. However, it was not possible to easily apply a predetermined initial tension to the belt.
