TRANSMISSION MECHANISM WITH CLUTCH AND ACTUATOR USING SAID TRANSMISSION MECHANISM

摘要

Provided are: a transmission mechanism that simplifies a work process and with which manual operation can be easily performed; and an actuator equipped with said transmission mechanism. The transmission mechanism for transmitting a driving force from an input shaft to an output shaft is provided with: a first rotating member to which the driving force is applied from the input shaft side; a second rotating member for applying the driving force on the output shaft; a through shaft, which rotates together with the first rotating member and passes through the second rotating member so as to dispose same concentrically with the first rotating member; a first restriction part that is disposed on the first rotating member-side of the second rotating member and rotates together with the second rotating member; and a second restriction part that rotates together with the through shaft and is disposed so as to engage and disengage freely with the first restriction part. The through shaft protrudes from one end of the second rotating member and is provided with a coupling mechanism with a first coupling member that can move in the axial direction and a second coupling member that faces the first coupling member and is disposed so as to engage and disengage freely as a result of movement of the first coupling member. One end of the first coupling member is provided with a cam member that is rotatably installed, and an engaging part for engaging with a cam groove formed so as to extend in the radial direction of the cam member.
