ROTATING DAMPER

摘要

A rotating damper, wherein a cam member (5) installed in a first chamber (R1) rotatably and unmovably in axial direction is connected unrotatably to a rotor (3) through a connection shaft part (52) passing through a piston (4), a second cam mechanism (10) installed between the cam member (5) and the piston (4) allows the piston (4) to move in one direction when the rotor (3) rotates in the same direction and, according to that rotation, the cam mechanism moves the piston (4) from a second chamber (R2) side to the first chamber (R1) side, and moves the piston (4) in the same direction by the same amount when the rotor (3) rotates in the other direction and, according to that rotation, the cam mechanism (7) allows the piston (4) to move from the first chamber (R1) side to the second chamber (R2) side.
