PROBLEM TO BE SOLVED: To suppress deformation with high-speed rotation in direct connection of an engine side and a transmission side, in a lock-up damper of an automobile or the like.SOLUTION: A substantially discoid torque transmission plate 31 is used for elastically transmitting torque from an engine side to a transmission side through a coil spring. In the torque transmission plate, a plurality of opening parts 39 for spring holding is formed with predetermined intervals in a circumferential direction, and one or a plurality of ribs 41 is formed from the gap between adjacent opening parts 39 for spring holding toward an outer edge direction.SELECTED DRAWING: Figure 2 |
