PROBLEM TO BE SOLVED: To provide an actuator and a self-locking mechanism thereof which have high transmission efficiency and which can achieve the self-locking of an electric parking brake system.SOLUTION: An actuator for an electric parking brake system includes a motor, an output member, and a speed reduction device. The speed reduction device includes a transmission mechanism and a self-locking mechanism. The self-locking mechanism includes a fixed member, first and second rotating bodies, and a spring. The second rotating body transmits torque to the output member via a planetary gear mechanism. The spring prevents the brake from driving the motor.SELECTED DRAWING: Figure 3

    【課題】高伝達効率を有するとともに、電動パーキングブレーキシステムの自動ロックを実現できるアクチュエータ及びその自動ロック機構を提供する。【解決手段】電動パーキングブレーキシステムのアクチュエータが、モータと、出力部材と、減速装置とを含む。減速装置は、伝達機構と、自動ロック機構とを含む。自動ロック機構は、固定部材と、第1及び第2の回転体と、ばねとを含む。第2の回転体は、遊星ギア機構を介して出力部材にトルクを伝達する。ばねは、ブレーキがモータを駆動するのを防ぐ。【選択図】図3
