2. Description of the Related Art A rotary shelf for a truck of this type is used for storing and managing a truck for loading a truck in a loaded state. A bogie support portion is provided which is inclined upward to prevent the bogie from sliding and falling naturally.

[0003] In this type of conventional cart-type rotary shelf, for example, as described in Japanese Utility Model Laid-Open Publication No. 1-126315, the upper end of a rear vertical wall portion of a substantially L-shaped cart support is provided. At the lower end, a member to which a wheel or a roller engaging with the guide rail is pivotally supported and to which a drive chain is connected is fixedly provided.

[0004]

In the conventional construction as described above, a pair of upper and lower endless guide rails are attached to a frame located inside the horizontal circulation path of the bogie support table, and an endless drive chain is stretched. However, if this frame and many trolley supports are transported separately, and the two are to be integrated at the installation site, each trolley support should be engaged with the guide rails at the installation site, and already stretched. The bogie supports must be connected to the installed drive chains at equal intervals, and the assembling work at the installation site requires a great deal of labor and time. Therefore, in the past, the entire assembly had to be transported to the installation site after assembling in the factory, and the transportation and installation of large shelves with large trolley supports from the front and rear sides of the frame and both ends in the length direction were enormous costs. However, there was a drawback.

Further, when the carriage support having a substantially right-angled L shape is supported by the guide rail, the carriage engages with the guide rail such that the carriage support of the carriage support inclines at a predetermined angle upward. When a member to which a wheel or a roller is pivotally supported and to which a drive chain is coupled is fixedly protruded from an upper end and a lower end of a rear vertical wall portion of the bogie support base, each of these members and a rear vertical wall of the bogie support base are provided. The two parts must be welded with a predetermined angle between them, and there is a drawback in that the assembling of the bogie support takes a lot of trouble.

From this state, the vertical wall portion of the support base body is tilted rearward with the fitting portion between the pair of lower left and right bolts and the mounting hole on the moving frame side as a fulcrum, so that a pair of upper left and right bolts of the vertical wall portion is formed. Can be inserted into the mounting holes of the pair of upper and right mounting seats on the moving frame side.

That is, the support base body is moved closer to the front surface of the movable frame so that the four bolts on the vertical wall side of the support base body are simultaneously inserted into the four mounting holes on the movable frame side, It is not necessary to insert a bolt between both the support base body side and the moving frame side while holding the bolt in a fixed position, and only a pair of lower left and right bolts are inserted into the mounting holes on the moving frame side to support the supporting base. With the entire weight of the main body deposited on the moving frame side, simply tilting the support main body down to the rear,
The bolts can be inserted into the four mounting holes on the moving frame side, and a nut may be fastened to each bolt in such a state.

Therefore, according to the configuration of the present invention, since the hand truck for transporting cargo is supported, the operation of attaching the large L-shaped support base body, which is large and heavy, to the front surface of the moving frame is extremely difficult. It can be done easily and easily.
