<P>PROBLEM TO BE SOLVED: To solve such problems that driving force cannot be transmitted by setting the rotation direction of a one-revolution clutch in a driving rotation direction reverse to the rotation direction of a cylinder part of a friction clutch. <P>SOLUTION: A clutch device includes: the one-revolution clutch M2 which performs ON/OFF control for transmission of a driving force; the friction clutch M1 which transmits the driving force through a friction force pressure-welding to the outer circumferential surface of the cylinder part 42; and a pivoting member M3 which includes a second lever 301 link-connected to a first lever 102 and a third lever 303 provided with an engagement part 304 engageable to an engagement projection 205 provided to a clutch ring 207, and pivots around a pivot point P positioning in the downstream side of the cylinder part 42 in a rotation direction that is the driving rotation direction of the one-revolution clutch M2. In addition, the clutch device also includes a spring 203, wherein the engagement part 304 contacts with the engagement projection 205 from a direction opposing to an energizing direction B of the spring 203 that is an elastic member, and then the engagement part 304 separates from the engagement projection 205 toward the same moving direction A as the energizing direction B of the spring 203. <P>COPYRIGHT: (C)2012,JPO&INPIT |
