Abstract

PROBLEM TO BE SOLVED: To allow protrusions for preventing a foot-warmer frame from being shifted horizontally to combinedly function as a coupling tool for coupling casings freely to decompose. SOLUTION: Cutouts 21 are formed in ends of adjacent casings 17 of a casing frame for preventing the casings 17 from being vertically shifted each other even when the ends are put on the other. A vertically penetrating througth-hole 22 is formed in the end of the casing 17 which becomes an upper side when the ends of the casings 17 are put on the other, and a recess 23 is formed in the end of the casing 17 which becomes a lower side, communicated with the through-hole 22. Protrusions 24 are fitted to the through-hole 22 and the recess 23 such that an upper part thereof is protruded. By placing a foot-warmer frame on the casing frame such that the protrusions 24 are fitted to the recess the foot-warmer frame can be prevented from being shifted horizontally.
