A roller is provided, a rotating shaft is erected between the left and right vertical frames, and a driving member for raising and lowering an elevating pallet is fixed to both ends of the rotating shaft, and the driving member is provided on a guide member provided on the vertical frame. A suspending member of an elevating pallet supported and guided is connected, and a speed reducer comprising a group of gears for transmitting power from a motor is provided on the rotating shaft, and the speed reducer is arranged inside a vertical frame and It is characterized by being fixed to a frame.

[0007]

When the vehicle is stored in the pallet of the trolley, the pallet is in the lower parking space when the pallet is in the lower parking space. After descending, the vehicle is placed on the lifting pallet. Thereafter, the elevating motor is operated to rotate the drive member together with the rotating shaft in the forward direction, the hanging member is hung, and the elevating pallet is raised to the storage position. When taking out the vehicle, the reverse operation is performed.

When the elevating pallet is lifted and lowered, the self-weight of the elevating pallet and the reaction force generated by the operation of the elevating motor act on the traversing vehicle. However, the guide member for guiding and supporting the suspension member and the reduction gear are vertically moved. Since it is provided on the frame,
Only by increasing the strength of only the vertical frame, the horizontal frame needs to have enough strength to connect the left and right vertical frames.
