Electric actuator
The invention provides an electric actuator capable of preventing heated air from staying in a housing. An electric actuator (40) is provided with: an electric motor (140) having a drive shaft (151); an input shaft (153) connected to the drive shaft; an input gear (152) that rotates integrally with the input shaft; an output gear (160) that rotates on the basis of power transmitted from the input gear; and a housing (100) that accommodates the motor, the input shaft, the input gear, and the output gear. The input shaft has a first shaft portion (154) extending from the input gear toward a drive shaft of the motor, and a second shaft portion (155) extending from the input gear in a direction opposite to the first shaft portion. The second shaft portion of the input shaft has an outer peripheral groove (155a) extending so as to advance in the circumferential direction as the second shaft portion advances in the axial direction. The housing has an exposure hole (123) that exposes the second shaft portion of the input shaft to the outside.
本发明提供一种能够抑制被加热的空气滞留在外壳的内部的电动促动器。电动促动器(40)具备：具有驱动轴(151)的电动机(140)；与驱动轴连结的输入轴(153)；与输入轴一体地旋转的输入齿轮(152)；基于从输入齿轮传递的动力而旋转的输出齿轮(160)；以及收容电动机、输入轴、输入齿轮及输出齿轮的外壳(100)。输入轴具有从输入齿轮朝向电动机的驱动轴延伸的第一轴部(154)和从输入齿轮向与第一轴部相反的方向延伸的第二轴部(155)。输入轴的第二轴部具有以随着沿轴向前进而沿周向前进的方式延伸的外周槽(155a)。外壳具有使输入轴的第二轴部向外部露出的露出孔(123)。
