<p>PROBLEM TO BE SOLVED: To perform positioning in the axial direction of a torque transmission member by a simple structure. SOLUTION: A coupling 1 is provided with the caselike torque transmission member 3, the shaftlike torque transmission member 5 inserted into the caselike torque transmission member, a main clutch 7 arranged between both torque transmission members 3 and 5, a pilot clutch 11 operated intermittently by an operation means 21, and a cam mechanism 9 operating by receiving a transmission torque applied on both torque transmission members 3, 5 when connecting the pilot clutch 11 and connecting the main clutch 7 by a thrust force generated in the axial direction. A stepped part 53 is formed in the shaftlike torque transmission member 5 to perform positioning in the axial direction of the torque transmission member 5 by a cam member 17 on one side in the cam mechanism 7.</p> |
