Abstract: An opening/closing apparatus of a canvas for a load transport vehicle is provided, which does not require a large working space. The apparatus has support posts raised at least at the front and tail ends of the rear body of the load transport vehicle and the canvas which covers the rear body by way of the support posts is lifted and lowered along the support posts, the apparatus including: a drum and has an outer diameter larger than that of drum; a wire which is taken up at one end thereof by the pulley and is connected at the other end of the lower portion of the rear body; a driver mechanism which is provided between said drum and the pulley, which causes the pulley to rotate integrally with the drum when the tension of the wire wound on the pulley is less than a predetermined value, and which causes the pulley to slide with respect to the drum when the tension is equal to or more than the predetermined value.
