PROBLEM TO BE SOLVED: To provide an air conditioning device high in anti-vibration rigidity since, in a blower-offset-type air conditioning device for a vehicle, the anti-vibration rigidity is relatively low, and thus, the mounting rigidity of the device to the vehicle is reduced and vibration and noise are transmitted into a vehicle cabin through an instrument panel. SOLUTION: The air conditioning device includes an air conditioning unit 10 provided with an air conditioning case 11 in which air-conditioning air flows, a blower unit 20 arranged at a side the air conditioning unit 10 so as to be offset for generating an air flow toward the air conditioning unit 10, and a cylindrical connecting duct 30 for connecting a blow-out port 21 of the blower unit 20 and an opening 14 formed at the side wall 13 of the air conditioning case 11. The air conditioning unit 10 has an evaporator 40 in the air conditioning case 11 which is arranged close to the opening 14 and has higher rigidity than that of the air conditioning case 11. The side wall 31 of at least a part of the connecting duct 30 is arranged so as to be overlapped with the side face 41 of the evaporator 40 when viewed in parallel to the side wall 31. In proximity to the opening 14, the width W2 of an air passage 12 of the air conditioning unit 10 is made narrower than the width W1 of an air passage 33 of the connecting duct 30 by the evaporator 40.
