A portion of a draft duct in an air conditioning unit upstream from a heater core is divided into three passages. Each of the divided passages is provided with air mix doors 9a, 9b, and 9c that distribute air into a warm air passage and a cool air passage at a predetermined ratio. The air mix doors
A portion of a draft duct in an air conditioning unit upstream from a heater core is divided into three passages. Each of the divided passages is provided with air mix doors 9a, 9b, and 9c that distribute air into a warm air passage and a cool air passage at a predetermined ratio. The air mix doors 9a and 9b are driven by first slide systems 34a and 34b having drive gears 21a and 21b that mesh with racks 20a and 20b of the air mix doors 9a and 9b, and support shafts 22a and 22b that support the drive gears 21a and 21b. The air mix door 9c is driven by a second slide system 35c having a drive gear 21c that meshes with a rack 20c of the air mix door 9c and that is supported by a support shaft 22c, and a second auxiliary gear 24a that meshes with a first auxiliary gear 24b supported by the support shaft 22c and that is supported by an auxiliary support shaft 25.
