PROBLEM TO BE SOLVED: To reduce the size of the vehicular longitudinal direction of a heater unit part. SOLUTION: A plate-like air mix door 25 is rotatably disposed by a rotary shaft 25a extending in the vehicle width direction, an entrance opening part 24 is disposed on one side face part in the shaft direction of the air mix door 25 in a case 21, so as to be superposed with the rotational operation space 31 of the air mix door 25 in the vehicular longitudinal direction. A blow-out mode door 39 opening/closing a plurality of blow-out opening 34 to 36 is integrally constituted of a rotary shaft 39c extending in the vehicle width direction and of a rotary door structure having an arc-shaped outer peripheral wall 39a opening/closing the plurality of blow-out openings 34 to 36. The blow-out mode door rotary shaft 39c is disposed on the vehicle front side of the air mix door rotary shaft 25a in the vehicular longitudinal direction. COPYRIGHT: (C)2004,JPO
