AUTOMOBILE COMPONENT ACTUATOR

摘要

PROBLEM TO BE SOLVED: To obtain an automobile component actuator for which a neutral return spring is not necessary.

SOLUTION: A cam projection 22 located on a stop position A is always provided to a rotational member 15 rotated by a motor 12, and a cam groove 23 engaging the cam projection 22 therewith is provided at an output lever 18. The cam groove 23 includes a circular arc passage 24 with an output shaft 17 as the center and a first cam surface 25 and a second cam surface 26 facing one side of each of them to the circular arc passage 24 and connecting the other side of each of them to each other. When the output lever 18 is rotated in the case the cam projection 22 is located on the stop position A, the cam projection 22 relatively moves inside of the circular arc passage 24. When the rotational member 15 is rotated in either one of directions, the cam projection 22 is separated from the circular arc passage 24 to pushingly move the output lever 18 to a first position or a second position by abutting on the first cam surface 25 or the second cam surface 26.
