Abstract
A foldable frame structure for trailer so designed that the distance between the pivot connection center of each pivot holder and the left/right side frame and the topmost edge of the left/right frame bar of the bottom frame is greater than the distance obtained by deducting the width of the collapsed bottom frame from the height from the left/right frame bar of the bottom frame to the topmost edge of the left/right side frame. Thus, the left side frame and the right side frame can be individually collapsed and closely attached to the bottom frame in one step. The present invention can greatly save the transportation volume and simplify the folding structure and folding action, and thus achieve the purpose of user's convenient collection and carrying.
