Claims (1)

[Claims for Utility Model Registration] 1. Frames arranged substantially parallel to each other on both the left and right sides of the installation surface, struts suspended vertically upward from substantially midpoints in the longitudinal direction of each frame, and their arrangement in the longitudinal direction. The position is such that the center of gravity in the front and rear direction is located forward of each of the pillars,
a carrier connected to each of the columns so as to be slidable in the vertical direction while maintaining a substantially horizontal state; a drive shaft disposed in the left-right direction at the rear of each of the frames and rotated by a drive source; Drive wheels fixed near both left and right ends of the drive shaft, rotatable guide wheels provided near the top ends of each of the pillars, and wrapped around each of the drive wheels and guide wheels on both the left and right sides, respectively. one end side restricts downward movement near an intermediate portion of the carrier carrying a vehicle in the longitudinal direction, and the other end restricts upward movement of the rear end side of the carrier carrying a vehicle. A two-tiered parking device, comprising: a chain disposed to restrict the movement of the vehicle; and a two-stage parking device in which the chain is moved by rotation of the drive wheel to move up and down a carrier on which a vehicle is mounted, the rear end side of the carrier. At the other end of the chain, which is arranged to restrict upward movement, the length does not change due to the weight of the carrier carrying the vehicle, but is lengthened by the rotational torque of the forced drive of the drive wheels. A two-stage parking device characterized by being connected to an elastic body that changes the height of the parking device. 2. One end side of the chain is directly connected to the vicinity of an intermediate portion of the carrier in the longitudinal direction, and the other end side of the chain is directly connected to the vicinity of the rear end of the carrier with the elastic body interposed therebetween. The two-stage parking device according to claim 1. 3. One end side of the chain is connected and fixed to the upper part of the support column by being wound around a rotatable guide ring fixed near an intermediate portion of the carrier in the front-rear direction, and the other end side of the chain is connected to and fixed to the upper part of the support column. It is wrapped around a rotatable guide ring fixed near the rear end,
The two-stage parking device according to claim 1, wherein the two-stage parking device is connected and fixed to the rear part of the frame with the elastic body interposed therebetween.
