PROBLEM TO BE SOLVED: To set a laid-down type oil tank in a standing position to be pulled and moved with a caster attached to the trunk of the tank so that the capacity of the oil tank is increased and a greater number of oil tanks are handled in loading. SOLUTION: A stand and the caster are welded to one side of the laid-down type metal oil tank along a joint projection between two trunks. Joint pieces are welded in advance to the opposite side of the two trunks with regard to the stand and caster, and the two trunks are joined together. Subsequently, a handle and a latch holding an oil supply pipe are attached to the trunk, a groove is formed on the back of the trunk, and a cover having upper and lower positioning holes is welded outside of the groove. Then, a pulling handle having an elastic positioning projection is so inserted into the groove that the projection is hooked in the positioning hole. COPYRIGHT: (C)2007,JPO&INPIT
