PROBLEM TO BE SOLVED: To provide a vehicular air conditioner easily securing waterproofness inside/outside its case body. SOLUTION: The air conditioner comprises: the hollow case body 2; and a pipe connection means 1 provided near the inside of a wall part of the case body 2 for connecting a pipe inside the case body 2 and a pipe outside the case body 2. The pipe connection means 1 is characterized by having: a connection part 14 connected to the pipe outside the case body 2 via a penetration hole formed at the wall part of the case body 2; and an abutting member 13 having an abutting surface for pressurizing/abutting to a peripheral part of the penetration hole in the axial direction of the penetration hole. In the conventional art, a clearance in the circumferential direction of the pipe connection means is sealed with a grommet, etc., so as to eliminate the clearance between the pipe connection means and the case body and secure the waterproofness. In this invention, making the pipe connection means contact the case body in the axial direction, enlarges an abutting area even though the accuracy between the pipe connection means and the case body is not high, which enables to tolerate misalignment of the pipe connection means to some extent.
