Title:
TORSIONAL VIBRATION DAMPING DEVICE
Document Type and Number:
WIPO Patent Application WO/2000/077418
Kind Code:
A1
Abstract:
A torsional vibration damping device, wherein a spring storing part (6) is provided to store a spring (3) connected relatively rotatably to a drive plate (5) which is disposed opposedly to a hub plate (4) at an interval, the spring storing part (6) of the drive plate (5) connects a side plate (51) to the outer peripheral part of a drive plate main body (50), the spring is disposed between the side plate and the drive plate main body (50) so as to prevent its falling-off, and a plurality of axial projections (51g) which are formed at the tip of a flange (51f) formed on the outer periphery of the side plate are weld-connected in the state of being engaged with a notch part formed on the outer peripheral edge of the drive plate main body, whereby a reduction in diameter of the device by a reduction in space necessary for the outer periphery of the spring becomes compatible with a transmission of a high torque and also a high connecting rigidity can be obtained so as to prevent the spring from falling off in order to increase the reliability of the device.
