Claims (1)

[Scope of utility model registration request] A duct 1 communicating with an air outlet 5 is partitioned in the ventilation direction by a partition wall 2 to define a first duct 3 and a second duct 4, and a first damper 9 pivotally supported by the first duct 3 has an operating surface 13a and a floating surface. A first cam member 13 having sequentially arranged cam members 13b is fixed, and a second cam member 13 is pivotally supported on the second duct 4.
A second cam member 14 having an operating surface 14a and a floating surface 14b successively connected to the damper 10 is fixed to the damper 10, and an operating arm 17 of an operating lever 16 pivotally supported on the duct 1 is provided with an operating pin that engages both cam members 13 and 14. Fix 18,
The actuating pin 18 is located at the starting point of the actuating surface 13a and the starting point of the floating surface 14b when both dampers 9 and 10 are in the closed position, and at the starting point of both cam members when the first damper 9 is in the open position and the second damper 10 is in the closed position. 13, 14 intermediate part 13
A damper opening/closing device for a vehicle air conditioner, characterized in that the dampers 9 and 10 are located at the end points of the floating surface 13b and the operating surface 14a when both dampers 9 and 10 are in the open position.
