Abstract:
1. A vibration damping mechanism of a rotation shaft, comprising: a rotation shaft for outputting torque inputted from its input side end portion to its output side end portion, and a damping member having a fixed portion fixed to the rotation shaft, a frictional contact portion held in frictional contact with the rotation shaft, and at least one deflection arm portion extending in an axial direction of the rotation shaft between the frictional contact portion and the fixed portion, the frictional contact portion being provided with an urging means for urging the frictional contact portion toward the rotation shaft to be held in frictional contact with the rotation shaft at a predetermined contact pressure, and being supported on the fixed portion through the deflection arm portion to be deformable in the radial direction of the rotation shaft in response to deflection of the deflection arm portion.
