PROBLEM TO BE SOLVED: To provide a damper device for a vehicle capable of generating hysteresis torques different between an acceleration side and a deceleration side.SOLUTION: A small hysteresis torque H1 is generated by bringing a slide contact face 23 and a slide contact face 25 into slidably contact with each other in a region where a torsion angle &thetas; between a disc plate 12 and a hub member 14 is less than a prescribed angle &thetas;a at a positive direction side. Further when the torsion angle &thetas; becomes the prescribed angle &thetas;a or more at the positive direction side, a slide contact face 28 and a slide contact face 30 are slidably kept into contact with each other in addition to the slide contact of the slide contact face 23 and the slide contact face 25, thus hysteresis torque H3 due to the slide contact of the slide contact face 28 and the slide contact face 30 is added. Accordingly, the twisting angle &thetas; between the disc plate 12 and the hub member 14 can be made different between the positive direction side and a negative direction side.SELECTED DRAWING: Figure 2 |
