Title:

TORSIONAL SHOCK ABSORBER

Document Type and Number:

WIPO Patent Application WO/2011/070623

Kind Code:

A1

Abstract:

Provided is a torsional shock absorber wherein an optimum hysteresis torque can be set at the positive side and the negative side by a simple structure without increasing the number of components, so that the operability in a producing operation can be improved, and the production cost can be prevented from increasing. A torsional shock absorber (10) is constructed so that, when a hub (11) is twisted toward the positive side with respect to a side plate (17), the outer peripheral portions of spring sheets (31, 32) move along outside support pieces (20a, 21a) of the side plate (17), and when the hub (11) is twisted toward the negative side with respect to the side plate (17), the spring sheet (32) moves along the outside support pieces (20a, 21a). The sliding resistance between the spring sheet (31) and the outside support pieces (20a, 21a) is larger than the sliding resistance between the spring sheet (32) and the outside support pieces (20a, 21a).
