After being lifted up to the upper floor 15, the cart 33 is placed on the corner portion where the vertical rail unit 21 and the horizontal rail unit 23 intersect by pushing the cart 33 through the loading / unloading opening 30 by the pushing mechanism.

Then, the carriage 33 is moved vertically or horizontally along the vertical rail unit 21 or the horizontal rail unit 23 toward the desired storage position. The vertical movement is performed by rotating the motor 98 of the vertical drive mechanism 91, and the horizontal movement is performed by rotating the motor 113 of the horizontal drive mechanism 92.

When the carriage 33 moves from the vertical rail unit 21 to the horizontal rail unit 24, or from the horizontal rail unit 23 to the vertical rail unit 22, the traveling direction of the carriage 33 changes by 90 °. At this time, only the traveling direction changes to a right angle without changing the direction of the carriage 33.

That is, the carriage 33 is the turntable 1
When the vehicle moves to the corner where 25 is provided, the carriage 33 stops temporarily, and the four casters 57
However, it stops at a predetermined position on the turntable 125 as shown in FIGS. In this state, when the driving mechanism 91 (or 92) applies a force in the direction for switching the traveling direction of the carriage 33 to the carriage 33 to the carriage 33,
The wheel 60 and bracket 121 of the No. 7 turn 90 ° with the turntable 125 about the vertical axis C1.

In this case, since the turntable 125 rotates about the vertical axis C2, the above turning motion of the casters 57 is smoothed, so that all the four casters 57 change their directions at the same time in the moving direction of the carriage 33. .. Therefore, the switching of the traveling direction is smooth, and the casters 5
7 and the drive mechanisms 91 and 92 are not unduly applied.

When the boat A housed in the boat parking apparatus 10 is to be unloaded, the boat A is put in and taken out 30
