  • Patent number: 7857041
    Abstract: A rotary door for a vehicle air conditioner includes a rotation shaft, a door surface that is spaced from an axial line of the rotation shaft radially outside and is rotated integrally with the rotation shaft, and a seal portion provided at a peripheral end portion of the door surface. The door surface has a first door face at a center portion, and a second door face positioned at left and right sides of the first door face. The second door face has a radial dimension from the axial line, that is smaller than that of the first door face so as to form a door outer peripheral space between the seal portion of the second door face and a seal rib of an air conditioning case. Furthermore, the second door face is provided with an air guide plate extending radial outside for guiding air.
