PROBLEM TO BE SOLVED: To provide a piping sealing structure of a vehicular air conditioner capable of securing good attaching/detaching work efficiency of a heat exchanger arranged in an air conditioning case, preventing breaks and peeling of an airtight member when splitting the air conditioning case, and preventing deterioration of the sealing performance caused by displacement of the airtight member. SOLUTION: In the piping sealing structure of an air conditioning unit, heat exchange medium pipes 2, 3, 4 of an evaporator arranged in the air conditioning case 1 are connected through a panel opening part 5a of a dash panel 5 outside the air conditioning case 1, and the airtight member 7 is provided at a position of a case opening part 6 which the heat exchange medium pipes 2, 3, 4 penetrate through. The air conditioning case 1 comprises a fixed side case 11 and an attaching/detaching side case 12. The case opening part 6 is formed of a first split opening part 11a and a second split opening part 12a positions, both of which correspond to each other when the attaching/detaching side case 12 is fitted to the fixed side case 11. The airtight member 7 adhering to the fixed side case 11 is provided attachable/detachable to/from the attaching/detaching side case 12. COPYRIGHT: (C)2008,JPO&INPIT
