Since the parking frame moves only in the vertical direction and does not move in the lateral direction, the lateral wobbling of the vehicle is reduced. Therefore, even if the distance between the vehicles in the width direction is reduced, the vehicle does not collide with an adjacent vehicle, the parking space per vehicle can be reduced, and the storage capacity can be improved. Further, since the ascending / descending speed of the parking space can be increased, it is possible to shorten the loading / unloading time.

Since warehousing and unloading can be performed for each parking frame, warehousing and unloading can be performed at any position in a short time. Further, since the vehicle can be parked on the entire parking floor, the parking space is not wasted and the space can be effectively used.

Since the frame elevating means is self-propelled and is attachable to and detachable from the parking frame, it is not necessary to provide the same number of frame elevating means as the parking frames.
The cost can be reduced.

Since the frame elevating means is lifted and supported by the load supporting means, the elevating and lowering of the parking frame can be performed stably, and the load applied to the frame elevating and lowering means at the time of elevating and lowering the parking frame can be reduced. .

Since the vehicle can be moved and moved between the parking floors, the vehicle can be loaded and unloaded efficiently, and the time required for loading and unloading can be shortened.

Since the parking frame can be fixed at the intended height position by the frame fixing means, the frame elevating means can be released from the support of the parking frame. Therefore, the frame elevating means can be used for elevating and lowering other parking frames, so that a plurality of vehicles can be loaded and unloaded at one time, and the loading and unloading time can be further shortened and the waiting time can be shortened. it can.
