A roof installation unit to be disposed in a roof of a vehicle includes a plurality of exterior heat exchangers (16, 18, 19, 15A, 15B), a front-side opening formation portion (122), and a blower (131). The plurality of exterior heat exchangers are arranged in a vehicle traveling direction and configured to cool a refrigerant by heat exchange between the refrigerant and outside air. The front-side opening formation portion is disposed on a front side in the vehicle traveling direction with respect to the plurality of exterior heat exchangers. The front-side opening formation portion forms a front side opening (122a) through which the outside air is taken in from the front side in the vehicle traveling direction. The blower is disposed on an upper side in a vertical direction of a foremost exterior heat exchanger (15A, 16) located on a foremost side in the vehicle traveling direction. The blower generates a flow of outside air such that the outside air taken in via the front side opening passes through the foremost exterior heat exchanger, and the outside air having passed through the foremost exterior heat exchanger is drawn into the blower. A front side in the vehicle traveling direction of the foremost exterior heat exchanger is located on an upper side in the vertical direction with respect to a rear side in the vehicle traveling direction of the foremost exterior heat exchanger, and the foremost exterior heat exchanger is inclined with respect to the vehicle traveling direction.
