To make downsizing easier and provide a self-lock function.SOLUTION: An actuator device 21 includes a driving gear 41 and a driven gear 42 which respectively have rotation axes La, Lb arranged parallel to each other and engage with each other. The driving gear 41 is provided with a first engaging tooth 61 having a protruding tip part 63. The driven gear 42 is provided with a second engaging tooth 62 having a recessed tip part 64. Further, the actuator device 21 has a state that the protruding tip part 63 and the recessed tip part 64 face each other. Further, when the driving gear 41 rotates from the state in first, a gear tooth 41xa located adjacent to the first engaging tooth 61 is engaged with the second engaging tooth 62 of the driven gear 42 by rotation of the driving gear 41. When the driven gear 42 rotates in first, the recessed tip part 64 is engaged with the protruding tip part 63 to cause interference between the first engaging tooth 61 and the second engaging tooth 62 and thereby restrict rotation of the driven gear 42.SELECTED DRAWING: Figure 9 【課題】小型化容易にセルフロック機能を付与する。【解決手段】アクチュエータ装置２１は、並行する回転軸Ｌａ，Ｌｂを有して互いに噛合する駆動ギヤ４１及び従動ギヤ４２を備える。駆動ギヤ４１には、凸状先端部６３を有した第１係合歯６１が設けられ、従動ギヤ４２には、凹状先端部６４を有した第２係合歯６２が設けられる。また、アクチュエータ装置２１は、これらの凸状先端部６３と凹状先端部６４とが互いに対向する状態を有する。更に、この状態から駆動ギヤ４１が先に回転する場合には、その駆動ギヤ４１の回転によって、第１係合歯６１の隣に位置するギヤ歯４１ｘａが従動ギヤ４２の第２係合歯６２に噛合する。そして、従動ギヤ４２が先に回転しようとした場合には、凹状先端部６４が凸状先端部６３に係合して第１係合歯６１と第２係合歯６２とが干渉することにより、その従動ギヤ４２の回転が規制される。【選択図】図９
