REVERSE ROTATION PREVENTION MECHANISM AND MOTOR WITH SPEED REDUCER
PROBLEM TO BE SOLVED: To provide a mechanism for achieving stable reverse rotation resistance.SOLUTION: A reverse rotation prevention mechanism 100 is provided on a torque transmission path between an output shaft and a motor drive shaft. The reverse rotation prevention mechanism 100 comprises: a first friction force generation part configured so as to inhibit a lock plate 38 provided on the torque transmission path from rotating relatively to other members when external force has been applied to the output shaft; and a second friction force generation part configured so that part of the lock plate 38 is pressed to generate brake force for preventing reverse rotation when external force has been applied to the output shaft. The first friction force generation part is provided in an area different from that of the second friction force generation part.SELECTED DRAWING: Figure 3
【課題】安定した耐逆転性を実現する機構を提供する。【解決手段】逆転防止機構１００は、出力軸とモータの駆動軸との間のトルク伝達経路に設けられている。また、逆転防止機構１００は、出力軸に外力が加わった場合に、トルク伝達経路に設けられたロックプレート３８が他の部材に対して相対回転することを抑制するように構成された第１摩擦力発生部と、出力軸に外力が加わった場合に、ロックプレート３８の一部が押し付けられることで逆転を防止する制動力を発生するように構成された第２摩擦力発生部と、を備える。第１摩擦力発生部は、第２摩擦力発生部と異なる領域に設けられている。【選択図】図３
