<p>PROBLEM TO BE SOLVED: To provide an actuator that is able to easily form and release in a housing part a structure that prevents nut separation, able to easily form the housing part, and also able to ensure the strength of the housing part sufficiently.SOLUTION: In an actuator 10 having a housing space 31 formed by combining a lower housing 30 (one housing member) and an upper housing 40 (the other housing member), a mounting part 200 is provided on the external surface of a peripheral wall part 34 of the lower housing 30. Additionally, the mounting part 200 has a housing part 220 in which a nut 250 is inserted, and a side face 200b of the mounting part 200 has an insertion port 221 for inserting the nut 250. The upper housing 40 has a coming-off prevention wall part 41 arranged opposite to the insertion port 221. Thus, the coming-off prevention wall part 41 prevents the nut 250 from separating from the inside of the accommodation part 220.</p> |
