Provide is a vehicle air conditioning device, in which a plurality of blow-off mode switching dampers are turned by a link mechanism, for enabling selective switching of blow-off modes, the link mechanism including: levers respectively provided to rotating shafts; and a turnable link (21) including a plurality of cam grooves (25, 26) on each of which a pin provided to each lever slides. A rail portion (27, 28) is provided in any one of an inner side surface of the cam groove (25) and an outer peripheral surface of each pin, and the cam groove (25) and the pin are in contact with each other through the rail portion (27, 28). Accordingly, it is possible to suppress abnormal noise that is generated when foreign substances are caught in a sliding surface (rail surface) between the cam groove and the pin. The contact surface between the cam groove and the pin is made smaller by providing the rail portion, and sliding frictional force can thus be reduced. Hence, the operability of the link mechanism can be enhanced. |
