Claims

[Scope of utility model registration request]

A damper that opens, closes, or switches the airflow passage in the heater unit, one side of the damper is pivotally attached to the wall of the airflow passage via a damper shaft, and an auxiliary link that rotates the damper at one end of the damper shaft. is engaged, and the rotation of the damper adjusts the mixture ratio of cold air and hot air and selectively distributes it to each outlet, in order to offset the damper's own weight and the moment around the damper axis due to ventilation. A spring is attached, one end of which engages with the auxiliary link that engages with the damper shaft, and the other end of which engages with the outer wall of the heater unit, to generate a moment around the damper shaft approximately in the middle of the damper's rotation range. An air conditioner for automobiles in which a spring force is applied to reverse the rotation.
