The second embodiment differs from the first embodiment in the structure of the arm supporting the pressing roller. Other points are substantially the same as those of the first embodiment. In the second embodiment, the arm (22) is formed of a member having a length whose base end is supported by the frame plate (7) by a fixed shaft (21),
(23) is rotatably supported, and a pressing roller (24) is rotatably supported on the way. The arm (22) is arranged in a pair on the upper side and the lower side of the driving rotary body (6). The pressing roller (24) is connected to the arm (2
It is pivotally supported by a rocking plate (25) pivotally supported by 2). The arm (22) is provided with a spring (2) extended on the fixed shaft (21).
Due to the resilience of (6), it is constantly urged away from the driving rotary body (6). The belt-shaped traveling body (4) is wound around a load receiving roller (23) pivotally supported at the tip of the arm, and the arm (22) is driven by the driving rotator () against the elastic force of the spring (26). 6)
, And the pressing force fluctuates according to the magnitude of the applied load. After the belt-shaped traveling body (4) is wound around the load receiving roller (23), the belt-shaped traveling body (4) is mounted on the driving rotary body so as to make substantially one round around the outer peripheral surface of the driving rotary body. When the belt-like traveling body (4) travels with a load placed thereon, the arm (22) swings toward the driving rotating body (6), and the driving rotating body (4) is pressed with a pressing force corresponding to the magnitude of the load. The pressing roller (24) is pressed against the outer peripheral surface of 6). Upon receiving the pressing force of the pressing roller, the belt-shaped traveling body comes into close contact with the outer peripheral surface of the driving rotating body (6), and a frictional force corresponding to the pressing force is generated, and the rotation is transmitted. Since the arm (22) pulls the belt-shaped traveling body (4) by the elastic force of the spring (26) added to the arm, it is possible to simultaneously prevent the belt-shaped traveling body from loosening. It becomes possible to eliminate the need for the locking mechanism as shown in FIG.
