Further, in a device using a hydraulic cylinder and a swing link as a drive device for rotating the rotating arms, the sprocket is set so that the pair of rotating arms are at the same angle so that the car housing cage is supported horizontally. After setting the wheel and chain, activate the hydraulic cylinder to push up the rotating arm, and the rotating arm will rotate to a position slightly beyond the center of the column. At this position, the weight of the rotating arm, the car housing cage, and the like acts to rotate the rotating arm in the same direction, so that when the pressure of the hydraulic cylinder is reduced, the car housing cage rotates to the parking place.

In this way, the automobile housing cage moves along the circumference of the same radius as the suspension shaft at the tip of the rotating arm. During this movement, the sprocket wheel and chain keep the car storage cage in a vertical position. Next, when the hydraulic cylinder is moved backward at the position moved to the parking place, the end of the swing link is pulled up by the hydraulic cylinder, and the swing link rotates to a position beyond the center of the support column. If the hydraulic cylinder is pressurized when the rocking link reaches this position, the weight of the hydraulic cylinder causes the rocking link to continue rotating and to be set at a position opposite to the initial position. Since the position of this swing link is the starting position when the parked vehicle is leaving, it can be moved to the road side by the same operation as described above.

In this case, the position and height of the parking place and the height of the fence to be overcome can be dealt with by variously selecting the length of the rotating arm and the height of the fixed shaft of the support. It should be noted that if a sensor for detecting the position of the rotary arm is provided and the speed of the motor is controlled and the hydraulic pressure or the flow rate is controlled, the landing speed of the car housing cage and the necessary operation and operation speed can be controlled.
