PROBLEM TO BE SOLVED: To provide a door shaft part sealing structure of a switching door preventing part of blown air of a blowing out port of a vehicle air conditioner from being passed between the switching door and the door shaft and flowing-in to a closure side. SOLUTION: The door shaft part sealing structure (4) of the switching door comprises a door shaft part sealing part (5) and a sealing part retaining case (6) and is mounted to the switching door (10) including an air shutting off door base plate part (2) for shutting off blowing of air; an air amount restriction door base plate part (3) for restricting an amount of blown air; and the door shaft (1) for controlling opening/closing of the air shutting off door base plate part and the air amount restriction door base plate part. The door shaft part sealing part has a shaft support part (5-2) rotatably supported on the door shaft; and an elastically expandable semi-cylindrical outer peripheral surface (5-1) fixed to a part of a peripheral part on the air shutting door base plate part. The sealing part retaining case has a semi-circular part (6-1) for covering a periphery of the door shaft part sealing part; and an inner peripheral surface (6-2) contacted with a semi-circular outer peripheral surface (5-1) of the door shaft part sealing part.
