調整装置。[Claims for Utility Model Registration] Automatic belt tension adjustment that adjusts the tension of a belt that transmits power from a driving device to a driven device via an idle pulley to an appropriate value by automatically moving the idle pulley. The device includes a bracket, a guide member, a support shaft, a ratchet mechanism, and a compression spring that applies tension to the belt, the bracket is connected to the drive device, and the guide member is , attached to the bracket, the idle pulley is rotatably supported at one end of the support shaft, and the support shaft is guided by the guide member so that when the idle pulley moves, the idle pulley is rotatably supported. movable in a direction in which tension is applied, the compression spring is disposed between the support shaft and the bracket, and the support shaft is engaged with the bracket; The ratchet mechanism is provided at a joint between the support shaft and the bracket, and the ratchet mechanism allows the support shaft to move only in a direction that applies tension to the belt, and allows movement of the support shaft in the opposite direction. An automatic belt tension adjustment device characterized in that movement of the support shaft is prevented.
