<p>[Problem] In order to increase the torsion angle between a first rotating member and a second rotating member and enable low hardness to be achieved for an elastic member, thus improving attenuation capability with respect to torsional oscillation, a torsional oscillation attenuation device (1) is equipped with: a pair of disk plates (4, 5) to which rotation torque from an internal combustion engine is transmitted; input gears (9, 10) rotatably attached to the disk plates (4, 5); a boss member (7), which is provided so as to be capable of rotation relative to the disk plates (4, 5), and is equipped with an output gear (13) that engages the input gears (9, 10), and to which an input shaft (8) of a drive transmission system is spline fitted; and coil springs (14), one end of each of which is attached to the input gears (9) and the other end of each of which is attached to the input gears (10). Each input gear (9) has a crank member (15) that is radially offset from the gear pin (11) of the input gear (9), and that supports one end of a coil spring (14), and each input gear (10) has a crank member (16) that is radially offset from the gear pin (12) of the input gear (10), and that supports the other end of the coil spring (14).</p> |
