PROBLEM TO BE SOLVED: To prevent components connected by snap fitting from being loosened.SOLUTION: Each of a first projecting piece 112 and a second projecting piece 122 of a servo motor 1 is formed into a tip-opening shape, the first projecting piece 112 contacts with an engagement surface 432 in a state of being elastically deformed, and the second projecting piece 122 contacts with a pin seat surface 312a in a state of being elastically deformed. Consequently, between the first projecting piece 112 and the engagement surface 432, and between the second projecting piece 122 and the pin seat surface 312a, a gap does not occur, and thereby a servo motor 1 can be prevented from being loosened. |
