PROBLEM TO BE SOLVED: To miniaturize a build of an air conditioning unit, in a vehicular air conditioner wherein a plurality of blow-off opening parts are opened and closed by one rotary door. SOLUTION: A heat exchanger part 13 to exchange heat with air is provided in a case 11, and a blow-off mode switching part 22 to switch and distribute air having passed through the heat exchanger part 13 to a plurality of the blow-off opening parts 24-26 is disposed on the downstream side of the heat exchanger 13 in the case 11. A rotation shaft 28 and a rotary door 27 having a circumferential wall surface 27a to open and close the plurality of the blow-off opening parts 24-26 by rotating with the rotation shaft 28 as a center are provided in the blow-off mode switching part 22, and the outer diameter D of the rotary door 27 is set so that D≥0.8L is satisfied in regard to the maximum passage width size L on the upstream side of the rotary door.
