Abstract
A rotation direction switching device for switching the rotation direction of a drive shaft includes a pulley unit for switching the rotation direction of the drive shaft. The pulley unit has a forward rotation drive belt and a reverse rotation drive belt. The forward rotation drive belt extends between the forward rotation drive pulley and a forward rotation driven pulley. The reverse rotation drive belt extends between a reverse rotation drive pulley and a reverse rotation driven pulley. When the drive shaft is forwardly rotated, the forward rotation belt is placed in a tensioned state, and the reverse rotation belt is switched to a relaxed state. When the drive shaft is reversely rotated, the reverse rotation belt is placed in a tensioned state, and the forward rotation belt is switched to a relaxed state.
