## Abstract

A movable vehicle capable of carrying stackable chairs comprises a base frame, a roller connected to the base frame for carrying the base frame, and a supporting frame disposed in the base frame. The supporting frame has a V-shape support with an upward opening. Advantages include adjustability of the supporting frame for placing and moving the stackable chair, and the V-shape of the supporting frame can either be an upward convex column, or an upward board, so as to carry different stackable chairs.
