[Detailed description of the device]

[0001]

[Industrial applications]

 The present invention relates to a trolley that can be used for loading and transporting products to a predetermined place by loading them on a supermarket or a distribution center, or as a storage shelf for loading and storing products.

[0002]

[Prior Art]

 Conventionally, this type of trolley has a structure that detachably attaches shelf frames that can attach shelf plates to both ends of the trolley body, or a structure that attaches shelf plates to both ends of the trolley body and side frames on one side. Has become.

[0003]

[Problems to be solved by the present invention]

 Although the conventional dolly that attaches shelf frames to both ends of the dolly body has a simple structure, it has a drawback in that care must be taken because both sides are open. In addition, a dolly that attaches shelves and side frames to both ends and one side of the trolley body can easily load luggage, but it requires a shelf frame and side frames, increasing the number of parts and increasing the cost. In addition, there was a drawback that it was difficult to store and store shelf frames and side frames of different sizes.

In view of the above conventional drawbacks, the present invention provides a trolley that can be easily loaded and can be manufactured inexpensively without increasing the number of types of parts. It is an object.
