    摘要： A rotary damper (D) is constituted by: housings (11, 51); a silicon oil (21) being housed inside the housings (11, 51); a rotor (31) wherein a resistive portion (36) moving through the silicon oil 21 inside the housings (11, 51) is provided in an axial portion (32) which is housed inside the housings (11, 51) and projects from the housings (11, 51); and an O-ring (61) preventing the silicon oil (21) from leaking between the axial portion (32) and the housing (51), and multiple arc-like through-bores (37) are provided in the resistive portion (36) on a concentric circle, and depressed grooves (38) communicating with the arc-like through-bores (37) are provided. Accordingly, during the assembly, the air being mixed into the housing is not allowed to be excessively compressed, so that even if the rotor rotates bi-directionally, the noise being caused by the air being mixed into the housing can be prevented.

    摘要： A rotary damper is provided so that air incorporated into a housing during assembly is, not excessively compressed, whereby a generation of a peculiar sound due to the air incorporated into the housing can be prevented even though the rotor rotates in both directions, and so that the air is stopped and captured in a fixed place whereby influence on the generated torque can be reduced, and irregularity of the torque can be reduced progressively.A rotary damper includes a housing (11, 51), silicon oil housed inside the housing (11, 51), a rotor 31 housed inside the housing (11, 51), and having a shaft member (32) projecting from the housing (11, 51) and having a resistance member (36) moving through the silicon oil (21) inside the housing (11, 51), and an O-ring (61) for preventing leakage of the silicon oil (21) from between the shaft member (32) and the housing (51). A circumferential groove (54) is provided on an inner face of the housing (51) facing the resistance member (36).

    摘要翻译： 提供一种旋转阻尼器，使得在组装期间结合到壳体中的空气不被过度压缩，由此即使转子沿两个方向旋转也可以防止由于装入壳体中的空气引起​​的特殊声音的产生，并且因此 空气被停止并捕获在固定的位置，从而可以减小对产生的扭矩的影响，并且可以逐渐减小扭矩的不规则性。 旋转阻尼器包括容纳在壳体（11,51）内部的壳体（11,51），硅油，容纳在壳体（11,51）内的转子31，并且具有从壳体突出的轴构件（32） 并且具有通过所述壳体（11,51）内部的所述硅油（21）移动的阻力构件（36）和用于防止所述硅油（21）从所述壳体（11,51）之间漏出的O形环（61） 轴构件（32）和壳体（51）。 在壳体（51）的面向阻力构件（36）的内表面上设置周向槽（54）。
