<P>PROBLEM TO BE SOLVED: To prevent unintentional misoperation from a drive power-interrupted state to a drive power-transmitting state as well as attempt to improve durability. <P>SOLUTION: A clutch mechanism includes a rotor for returning a clutch rotating and synchronizing with a handle shaft which is connected to a clutch lever and to which a handle is attached, a clutch actuation piece 31 engaging to and disengaging from the rotor for returning the clutch, and a guide control part 45 for guiding and controlling the movement of the clutch actuation piece 31, wherein the clutch actuation piece 31 is brought to move on different movement loci K1, K2 along the guide control part 45 depending on switching states switching from the power-transmitting state to the power-interrupted state and a returned state returned from the power-interrupted state to the power-transmitting state, and the mobile resistance on the movement locus K2 moving when the clutch actuation piece 31 returns is brought to be larger than that on the movement locus K1 moving in the switching state. <P>COPYRIGHT: (C)2012,JPO&INPIT |
