Filed: 2017-02-21
Abstract: PROBLEM TO BE SOLVED: To properly secure friction resistance by an elastic body in a rotation direction while suppressing an increase in rigidity in a radial direction between an inner shaft and an outer shaft which are spline-fit to each other.SOLUTION: Since an axial length L1 of rubber (elastic body) 82 is longer than an axial length L2 of a core material 80, and a thick part 86 is arranged at an extension portion 82a extending from the core material 80 to an axial direction, rigidity in a rotation direction is raised by compressive deformation of the thick part 86, and friction resistance between a rotor shaft and the thick part can be secured while suppressing an increase in rigidity between a gear shaft (inner shaft) 42 and a rotor shaft (outer shaft) in a radial direction due to existence of a gap 92 irrespective of the compressive deformation of the thick part 86. Since the increase in the rigidity between the gear shaft 42 and the rotor shaft in the radial direction is suppressed, lowering of a coaxial adjustment action is suppressed and radial vibration resulting from misalignment is suppressed, and since the rigidity of the rubber 82 is raised and the friction resistance in the rotation direction becomes large, occurrence of rattling sound of a spline-fit part is suppressed by a buffer action by the friction resistance.SELECTED DRAWING: Figure 5
