A vehicle air conditioner to be installed in a passenger compartment S includes a casing, a piping component, and a seal. The casing accommodates a heat exchanger. The piping component supplies a heating medium to the heat exchanger or exhausts the heating medium from the heat exchanger. The sealseals a portion between the casing and a periphery of an opening P of a dash panel P of a vehicle. The dash panel P separates the passenger compartment S from an outside of the passenger compartment S. The piping component is inserted into the opening. The sealhas a surface facing the dash panel P and including a notch. The notchis positioned outside the periphery of opening P

In a casing (11), a rear guide (23) is formed above a cylindrical impeller (13) and a stabilizer (24) is formed below the impeller. A minimum gap dimension between the cylindrical impeller (13) and the stabilizer (24) on the outlet port (17) side has a value of 14% to 24% of the outer diameter of the cylindrical impeller (13). An angle between a straight line connecting the center of rotation of the cylindrical impeller (13) and a minimum gap position on the outlet port (17) side of the stabilizer (24) and the horizontal plane has a value of 38.degree. to 43.degree.. A minimum gap dimension between the cylindrical impeller (13) and the stabilizer (24) on the inlet port (16) side has a value of not smaller than 7% of the outer diameter of the cylindrical impeller (13). An angle between a straight line connecting the center of rotation of the cylindrical impeller (13) and a minimum gap position on the inlet port (16) side of the stabilizer (24) and the vertical plane has a value of 11.degree. to 15.degree..
