Abstract:
A damper apparatus includes a drive plate, a driven plate, torsion springs, and spring housing portions. The torsion springs each have a large arc spring and a small arc spring, and elastically couple the drive plate and the driven plate in the rotation direction and transmit torque. The spring housing portions have a support surface that can support the outer periphery of the large arc springs, and the support surface comes into contact with the outer periphery of the central portions, in the lengthwise direction, of the large arc springs. Also, gaps exist between the support surface and the outer periphery of the two end portions, in the lengthwise direction, of the large arc springs.
