Claims

[Scope of utility model registration request]

A plurality of window holes are formed in the output side plate and the input side plate, and at least two torsion springs are arranged in series in each window hole so that they can be freely compressed in the rotational direction, and the rotational direction can be moved between the two torsion springs. In a damper disk with a spring support interposed therebetween, a boss part of the spring support is formed radially inward from the torsion spring, and the boss part is swingably connected to an annular connecting plate via a pin, so that rotation of the support is prevented. A spring sheet is arranged on both sides of the spring sheet, and a cylindrical protrusion that fits into the torsion spring is formed on the end surface of the spring sheet on the torsion spring side, and a cylindrical protrusion is formed on the end surface of the spring sheet on the support side to lock the sheet. A groove is formed on both sides of the support in the rotational direction, into which the tooth can be inserted in the axial direction, and the spring seat is locked so that it cannot move outward by meshing with the tooth.
