However, in the above-mentioned conventional elevator type three-dimensional parking apparatus, the front and rear wheels of the automobile are supported inside the two side frames as a structure through which the fork-shaped stage can pass through the traverse carriage. Since the fork part is formed in a so-called cantilever state and these frame base end parts are assembled to each guide rail via the guide rollers, when the vehicle is placed on the fork part of the lifting lift and the lifting operation is started. The load lowers the inside of the fork, which causes twisting of the lifting lift. As a result, as shown in FIG. 5, the upper guide rollers face inward and the lower guide rollers move outward in each guide rail. There is a problem in that the operation is not smooth when the elevating lift is moved up and down because they are pressed against each other.

The present invention solves the above-mentioned conventional problems, and provides an elevator apparatus for an elevator type multi-level parking apparatus capable of suppressing twisting of the elevator lift and realizing a smooth operation of the elevator lift. The purpose is to do.
