Abstract: A vehicle air conditioning apparatus includes a housing having an air flow path therein. An air guide member is provided within a mixing zone where a first air flow flowing in from a first opening provided on the air flow path within the housing and a second air flow flowing in from a second opening are mixed, and guides the first air flow and the second air flow. A slide damper adjusts an opening degree of the first opening. The air guide member has a rectifying unit rectifying the first air flow to the mixing zone, and a deflecting unit arranged closer to the second opening than the rectifying unit and deflecting a flow direction of the first air flow from a direction of the second opening. The apparatus can suppress generation of noise at the mixing zone arranged with the air guide member including the rectifying unit.
