Claims

[Claims for Utility Model Registration] A damper lifter and a damper cam are slidably spline-coupled to each of two coaxial shaft axes, and their cam engagement surfaces are in contact with each other, and on the back side of the damper lifter, In a damper mechanism that is provided with a coil spring that presses both cam engagement surfaces toward the pressure contact side, there is a pressure between the damper cam and one of the shaft shafts in proportion to the contact pressure between the cam surfaces of the damper cam and the damper lifter. A friction damper mechanism characterized by having a friction transmission mechanism that increases and decreases frictional force.
