Title:
DAMPER DEVICE
Document Type and Number:
Japanese Patent JP2019132420
Kind Code:
A
Abstract:
To reduce an axial dimension of a hysteresis torque generating mechanism.SOLUTION: A damper device includes: a subplate 34 and a ring holder 35 to which torque is input; a drive plate 36 which is disposed so as to be rotatable relative to the sub plate 34 and the spring holder 35; multiple springs 37 which elastically connect the sub plate 34 and the spring holder 35 to the drive plate 36 in a rotation direction; and a hysteresis torque generating mechanism 14 which generates hysteresis torque when the sub plate 34 and the spring holder 35 and the drive plate 36 rotate relative to each other. The hysteresis torque generating mechanism 14 has a groove 34e and a wavy line 56. The groove 34e is formed on a side surface of the sub plate 34. The wavy line 56 is attached to the groove 34e and presses the drive plate 36 to the spring holder 35.SELECTED DRAWING: Figure 9
