20, a movable shelf frame 23B outside the fixed shelf frame 15,
The stock cart 36B constructed as described above differs in that the shelf board member 31 can be suspended from the movable shelf frame 23B.
Even in this case, the same operation and effect as those of the first embodiment of the present invention can be obtained.

The fourth embodiment of the present invention shown in FIGS. 20 to 22 differs from the first embodiment of the present invention mainly in that a bogie in which a base plate 7 is fixed to a square frame 2A. 1A
In addition, the first embodiment of the present invention can be applied to the stock cart 36C thus formed in that a pair of shelf frames 23, 23 detachably attached to both ends of the cart 1A are used. The same operation and effect as described above can be obtained.

In this embodiment, one or both of the pair of shelf frames 23, 23 attached to the cart 1A may be fixedly attached to the cart 1A.

As is clear from the above description, the following effects can be obtained in the present invention.

(1) A trolley, a pair of shelves mounted so as to face the front and rear ends of the trolley, and both ends of the pair of shelves can be attached to and detached from shelf support bars. In a stock cart comprising a shelf member locked to the shelf, the shelf member is formed on a shelf main body located between the pair of shelf frames, and on both sides of both ends of the shelf main body. Two pairs of hook-shaped locking pieces that are locked to the shelf support bar obtained by bending the U-shaped member bent into an L-shape; Since it is composed of two pairs of hanging locking pieces in a stacked state formed so as to protrude to
By engaging the hook-shaped engaging pieces of the shelf member with the shelf support bar of the shelf frame, the shelf member can be stored in the shelf frame in a suspended state. Therefore, it is possible to easily arrange the items.

(2) According to the above (1), the hook-shaped locking piece of another shelf board member is locked to the hanging locking piece of the stacked shelf board member suspended on the shelf frame. Thereby, a plurality of shelf board members can be stored and stored in a stacked state. Therefore, a plurality of shelf board members can be stored easily.

(3) According to (1), since the structure is simple, it can be manufactured at low cost.

(4) According to the second aspect, the same effects as the above (1) to (3) can be obtained, and the cart can be stored in a nesting state when not in use. Therefore, many can be stored in a small storage space.
