The present invention relates to an actuator for an electric vent of an automobile, and more particularly, to an actuator for an electric vent of an automobile, which can prevent a gear portion and a motor from being deformed and damaged by an external force applied to an operation knob even when the operation knob is subjected to an external force. In order to achieve the purpose, the present invention comprises: a forward/reverse rotation motor (100) which is driven by a signal output by a control device (500) and generates a driving force to continuously rotate a shaft (600) in the forward/reverse direction; an input gear (110) that rotates in one side direction and the other side direction in accordance with the rotation direction of a shaft (600) according to the driving force generated by the forward/reverse rotation motor (100); a reduction gear unit (200) that receives the rotational force transmitted through the input gear (110) and rotates in one direction and the other direction; and a slide gear section (300) that receives the rotational force transmitted by the reduction gear section (200) and rotates in one side and the other side, the slide gear section (300) comprising: a slide housing (310) in which a first coupling groove (311) and a second coupling groove (312) are formed in communication with each other on the left and right sides, and in which serrated teeth (313) that mesh with the reduction gear section (200) are formed on the outer peripheral surface; a sliding shaft (320), one side of which is inserted into a first coupling groove (311) formed in the sliding housing (310); the sliding rubber (340) is fixedly arranged between the sliding shaft (320) and the inner side surface of the first combination groove (311); a sliding bush (330) that is inserted into and inserted into the first coupling groove (311) in which the sliding rubber (340) is provided so that the other side part of the sliding bush (330) is pushed into and pulled out of the second coupling groove (312) so as to selectively achieve key-groove-type assembly and separation on one side part of a sliding shaft (320) that is inserted through the first coupling groove (311) in which the sliding rubber (340) is provided; and a housing (400) that keeps the slide housing (310) and the reduction gear part (200) in a state in which one side of the slide bush (330) and the other side of the slide shaft (320) are pulled out to the outside in a state in which the slide housing (310) and the reduction gear part (200) are interlocked with each other.

    本发明涉及一种汽车的电动通风口用执行器,更具体地,即使在操作旋钮受到外力的情况下,也可以防止齿轮部和电机因施加到操作旋钮的外力而变形及损坏。为了实现所述目的,本发明包括:正反转电机(100),由控制装置(500)输出的信号驱动,产生驱动力以使轴(600)沿正反方向持续旋转;输入齿轮(110),根据所述正反转电机(100)产生的驱动力,随着轴(600)的旋转方向,在一侧及另一侧方向旋转;减速齿轮部(200),接收通过所述输入齿轮(110)传递的旋转力,沿一侧及另一侧方向旋转;以及滑动齿轮部(300),接收通过所述减速齿轮部(200)传递的旋转力,沿一侧及另一侧方向旋转,所述滑动齿轮部(300)包括:滑动外壳(310),在左右两侧连通形成有第一结合槽(311)和第二结合槽(312),在外周面形成有与减速齿轮部(200)啮合的锯齿状齿(313);滑动轴(320),一侧部插入到形成在所述滑动外壳(310)的第一结合槽(311);滑动橡胶(340),固定设置在所述滑动轴(320)与第一结合槽(311)的内侧面之间;滑动衬套(330),以选择性地在滑动轴(320)一侧部实现键槽式组装及分离的方式使得另一侧部在第二结合槽(312)被推入抽出,所述滑动轴(320)贯通插入于设置有所述滑动橡胶(340)的第一结合槽(311);以及外壳(400),在所述滑动衬套(330)的一侧部和滑动轴(320)的另一侧部向外部抽出的状态下,使滑动外壳(310)与减速齿轮部(200)保持相互联动的状态。
