Claims

[Claims for Utility Model Registration] A pair of mutually parallel guide portions 22 and 23 are provided on one side of the fixed base 19 and the slide base 20 to which the passive pulley 46 is attached, and on the other side,
A slide portion 38 is provided between the guide portions 22 and 23 so as to be slidable in the longitudinal direction. A spring 53 is provided between the fixed base 19 and the slide base 20 to bias the driven pulley 46 in the direction in which the pulley 46 moves away from the driving pulley, and elastically supports the driven pulley 46 in the longitudinal direction of the guide parts 22 and 23. The passive pulley support device is characterized in that a leaf spring 58 is provided between the one guide section 22 and the slide section 38 for biasing the slide section 28 toward the other guide section 23. Passive pulley support device.
