ROTARY DAMPER, VALVE, AND METHOD FOR PREVENTING REDUCTION OF TORQUE OF ROTARY DAMPER FROM
The purpose of the present invention is to prevent a reduction in torque of a rotary damper due to wear of a valve. A rotary damper is provided with a valve (3) having a first end surface (3a) facing a first surface (4a) that blocks one end of an oil chamber (4), a second end surface (3b) facing a second surface (4b) that blocks the other end of the oil chamber (4), a back surface (3c) facing a curved surface (4c) of the oil chamber (4), and a valve part (3d) that closes an oil passage (5) formed between the valve and a rotor (2). The oil passage (5) is closed by the valve portion (3d) to prevent oil injected into the oil chamber (4) from flowing back through the oil passage (5), the valve (3) has recesses and projections (3k, 3l) on the back surface (3c), a gap (6) is formed between the concave portion (3k) of the recesses and projections (3k, 3l) and the curved surface (4c), the cross-sectional area of the gap (6) is reduced by the wear of the convex portion (3l) of the recesses and projections (3k, 3l), and the function of the valve portion (3d) is not impaired by the wear of the convex portion (3l).
本发明防止因阀的磨损导致的旋转阻尼器的转矩的降低。本发明提供一种旋转阻尼器，其特征在于，具备阀（3），阀具有与将油室（4）的一端堵塞的第一面（4a）相向的第一端面（3a）、与将油室（4）的另一端堵塞的第二面（4b）相向的第二端面（3b）、与油室（4）的弯曲面（4c）相向的背面（3c）、以及将形成在阀与转子（2）之间的油路（5）关闭的阀部（3d），通过阀部（3d）将油路（5）关闭而防止注入到油室（4）的油通过油路（5）逆流，阀（3）在背面（3c）具有凹凸（3k、3l），凹凸（3k、3l）的凹部（3k）在与弯曲面（4c）之间形成间隙（6），间隙（6）的截面积由于凹凸（3k、3l）的凸部（3l）的磨损而缩小，阀部（3d）的功能不因凸部（3l）的磨损而受损。
