Abstract
A mounting structure for a cam-type torque damper is provided to ease the assembling thereof, improve the maintenance properties thereof and prevent the variation in thrust direction restricting position due to loosening or the like. A collar is spline connected to an axial end of a crankshaft, and a primary gear, a lifter, a spring and a spring holder are fitted on the collar in that order. A cotter is fitted in a groove in the collar so as to restrict the spring holder with respect to the thrust direction position to thereby assemble the cam-type torque damper into a small assembly. The cam-type torque damper so made to be a small assembly is then fastened to the axial end of the crankshaft with a bolt. A concave cam is formed in a side of the primary gear, and a convex cam provided in an axial end portion of the lifter is brought into mesh engagement with the concave cam.
