The frictional force generated between the two parking devices 5 and the track 100 counteracts the pushing force exerted by the pushing device 2 on the second frame 12, so that the second frame 12 remains stationary with the track.

S5. The cart pusher is repeatedly pushed and reset in sequence, so that the pusher runs continuously to push the vehicle to be pushed along the track until the vehicle to be pushed reaches the designated position. In other words, the pusher repeats steps S3 and S4 in sequence, so that the pusher runs continuously to push the vehicle to be pushed along the track 100 until the vehicle to be pushed reaches the designated position.
