A vehicle air conditioning apparatus is provided that can prevent temperature variations of the air after the heat exchange in a radiator to reliably control the temperature of the air supplied to the vehicle interior. During the heating operation and the heating and dehumidifying operation, target degree of supercooling SCt when target air-blowing temperature TAO is a predetermined temperature or higher is set to SCt1 that is greater than SCt2 when the target air-blowing temperature TAO is lower than the predetermined temperature. When amount of air Ga supplied from indoor fan 12 is lower than a predetermined value, the target degree of supercooling SCt is corrected, which is set such that the degree of supercooling is lower than target degree of supercooling corrected when the amount of air Ga supplied from the indoor fan 12 is a predetermined value or higher.

A housing which forms one portion of a compressor case and which supports a bearing for a main shaft has formed therein: an opening through which gas to be compressed is sucked; a suction space extending in a cylindrical-shape from the opening toward the inside of the compressor; a first gas passageway extending from the suction space in the direction of the axis of the main shaft; and a second gas passageway for connecting the first gas passageway and the space in which the bearing for the main shaft is disposed. A shell which forms the other portion of the compressor case and which is fastened to the housing has formed therein a third gas passageway for connecting the first gas passageway and the internal space of a compression mechanism. The scroll compressor is characterized in that the first gas passageway and the third gas passageway are connected to each other in a region located further on the outer side of the main shaft in the rotation radius direction than the movable region of the bottom plate of a movable scroll. As a result of the configuration, in the scroll-type compressor, the sliding portions of the bearing, a lip seal, a thrust plate, etc. can be lubricated while the degree of superheat of suction gas is suppressed.
