PURPOSE:To prevent leak of air due to incomplete mounting in a structure for mounting a cooling unit between a blower unit and a heater unit by making a mounting bracket or body side bracket horizontally rotatable so as to permit horizontal rotation of the whole cooling unit. CONSTITUTION:When a cooling unit 23 is inserted between a blower unit 2 and a heater unit 4, only the portion forming an air inlet 13 comes in abutment against a guide flange 16 and a side surface 19 of the blower unit 2, and only a sealing material 21 of the air inlet 13 is compressed. Then, the reacting force of the sealing material 21 causes the whole cooling unit 23 to be horizontally rotated around a rotating shaft 27 in the direction A, so that communication is completed between an air outlet 12 of the blower unit 2 and an air inlet 15 of the heater unit 4 in an inclined manner with no gap therebetween. This structure assures mounting with no leak of air, despite of misregistration between the blower unit and the heater unit. |
