Hereinafter, a preferred embodiment of a door actuator of a vehicle air conditioner according to the present invention will be described in detail with reference to the accompanying drawings (the same components will be described using the same reference numerals).

First, referring to FIGS. 2 and 3, the door actuator of the present invention includes a case 10, and the case 10 includes a drive motor 12, a first output shaft 14, and a second output shaft 16. This is installed.

The drive motor 12 rotates forward and backward in accordance with the control signal of the air conditioning apparatus.

The first output shaft 14 is rotated by receiving the driving force of the driving motor 12, the first output shaft 14 is rotated in this way, is connected to the door 5a, for example, the mode door (5a) The mode door 5a is rotated.

As a result, the driving force of the drive motor 12 transmitted to the intermediate gear 44 can be transmitted to the first output shaft 14 through the first power transmission gear 46.

Further, when the "second control signal" is input, the swing arm 42 is pressed in the "second position" (Y) direction. Thus, the intermediate gear 44 installed on the swing arm 42 can be engaged with the second power transmission gear 48. As a result, the driving force of the drive motor 12 transmitted to the intermediate gear 44 can be transmitted to the first output shaft 16 through the second power transmission gear 48.

According to such a power transmission part 40, the drive motor 12 by configuring the intermediate gear 44 to swing in the "first position" (X) or "second position" (Y) as necessary, It is possible to selectively transmit the driving force of any one of the first output shaft 14 and the second output shaft (16).
