To use an actuator of a winding machine also as an actuator of a vertical location regulation mechanism and reduce its cost.

One end of a rope 12 of a winding machine 13 is fixed to a winding barrel, the other end 12a is drawn and guided toward a transferring direction moving away from a lifting rail HR through moving pulleys 14, 15 at the lifting rail HR and a fixed pulley 16 at a fixed rail R. There is provided a resilient biasing means 20 fixed to an end part 17b of a location regulation member 17 through a connecting plate 18 so as to bias the location regulation member 17 toward a transferring direction repelling from the lifting rail HR, and a spring constant (k) of the resilient biasing means 20 is set such that the location regulation means 17 and vertical location regulation members 23a, 23b are not interfered to each other when the lifting rail HR is lifted up or lifted down. The lifting rail HR ascends to wind up a rope 12 further by a winding-up machine 13, thereby the location regulation member 17 enters between the vertical location regulation members 23a, 23b against the biasing force of the resilient biasing means 20.
