Abstract
【解決手段】電動モータ11のロータ軸の回転をロックおよびアンロック可能なロック機構を、ギヤ減速機構13を形成する複数のギヤのうちの一つのギヤ33の側面周方向に設けられた複数の係止孔41と、その係止孔41に対して進退可能に設けられ、前進時に係止孔41に係合してギヤ33をロックするロックピン42と、そのロックピン42を進退させるリニアソレノイド43とで形成する。リニアソレノイド43におけるプランジャ49とロックピン42とを別部品として端面が軸方向で対向する同軸上の配置とし、ロックされるギヤ33からロックピン42に負荷されるモーメント荷重がプランジャ49に負荷されることのないようにして、プランジャ49をスライド自在に支持するボビン48の内径面が損傷するのを防止する。
