The present invention provides an air conditioning apparatus for use in an automobile which employs a cross-flow fan as a ventilator, so that the apparatus is made thinner. The apparatus of the present invention is provided with a first and a second stabilizer, and accordingly a compulsory vortex of the air which is effective to feed the air is able to be stabilized. Moreover, a rear guider and an upper diffuser are provided in the surface opposite to the stabilizers with respect to the cross-flow fan, with enhancing the stabilization of the air flow. The reduction of the air flow amount and/or the generation of noises because of the vortex of the air can be consequently prevented. In the automobile air conditioning apparatus of the present invention, an evaporator has its upper end arranged to be inclined towards the cross-flow fan, so that the air flow into the cross-flow fan runs smoothly. Because of the arrangement of the above-described first and second stabilizers and the cross-flow fan, according to the present invention, the compulsory vortex of the air is generated at the optimum position and positively, thereby to make it possible to secure sufficient air amount and also to reduce noises, while realizing smooth and continuous flow of the air inside the room of the automobile.
