<p><P>PROBLEM TO BE SOLVED: To provide a clutch device capable of certainly transmitting drive force of a driving source such as a motor from an input rotary member to a follower rotary member. <P>SOLUTION: The clutch device 1 includes the input rotary member 3, the follower rotary member 4 and a switching operation means 18 for switching both the rotary members 3, 4 between a transmission state where the drive force can be transmitted and an interruption state where the drive force is not transmitted. The switching operation means 18 has a radially movable member 5 disposed between both the rotary members 3, 4 in a radially movable manner, a pressing part 3b provided on the input rotary member 3 so as to press the radially movable member 5 when the input rotary member 3 is rotated normally, an engagement part 4b formed on the follower rotary member 4 and engaging with the radially movable member 5 pressed by the pressing part 3b, and a movement mechanism 19 for separating the radially movable member 5 from the engagement part 4b when the input rotary member 4 is rotated reversely. <P>COPYRIGHT: (C)2008,JPO&INPIT</p> |
