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.
【課題】スナップフィットにより結合する部品のがたつきを防止する。【解決手段】サーボモーター1の第1突起片112と第2突起片122を先開き形状とし、第1突起片112を弾性変形した状態で係合面432と当接させ、第2突起片122を弾性変形した状態でピン座面312aと当接させる。これによると、第1突起片112と係合面432との間、および第2突起片122とピン座面312aとの間に隙間が発生しないため、サーボモーター1のがたつきを防止することができる。【選択図】図3
