Title:
ROTARY DAMPER
Document Type and Number:
WIPO Patent Application WO/2011/039922
Kind Code:
A1
Abstract:
A first cam mechanism (8) is disposed between peripheral parts on the facing surfaces of a rotor (2) and a piston (3). A shaft (2c) is integrally disposed in the center of the facing surfaces of the rotor (2) and the piston (3). A pair of outer projections (9a, 9a) are disposed on the outer surface of the shaft (2c). A through-hole (3a), through which the shaft (2c) is inserted, is formed in the piston (3). A pair of inner projections (9b, 9b) are disposed on the inner surface of the through-hole (3a). Each outer projection (9a) is disposed in a manner enabling sliding between the inner projections (9b, 9b), and each inner projection (9b) is disposed in a manner enabling sliding between the outer projections (9a, 9a). After the outer projection (9a) has slid between the inner projections (9b, 9b), a second cam mechanism (9) is provided between the facing surfaces of the outer projection (9a) and the inner projection (9b), which are mutually facing when rotated by a prescribed angle.
