PROBLEM TO BE SOLVED: To provide a rotary damper device with a simple configuration of a seal mechanism in which shock generated when a rotating operation occurs upon opening or closing of a member or shock received by a mating member upon relative rotating operation generated between the members constituting a rotation transmitting system can be alleviated with brake force of viscous fluid.SOLUTION: Cam follower members 6 and cam members 18 converting relative rotation generated between the two members rotated to each other into a motion of linear direction are arranged, and a braking force is applied from a cylinder part 8 having a cylinder main body 9, piston 10 and piston rod 11 moved relatively in respect to the motion of linear direction. With this arrangement as above, irrespective of application of the braking force from viscous fluid against the rotation, viscous fluid leakage location becomes a sliding part of the piston rod 11 in a linear direction, so that it is possible to provide a less-expensive rotary damper device in which a simple seal mechanism such as an O-ring can be applied.SELECTED DRAWING: Figure 2
【課題】部材の開閉に係る回転動作時に生じる衝撃や、回転伝達系を構成する部材間に生じる相対的回転動作により相手部材が受ける衝撃を粘性流体の制動力により緩和することができる簡単な構造のシール機構で済むロータリダンパ装置を提供する。【解決手段】相対的に回動する二つの部材間に生じる相対的な回転を直線方向の移動に変換するカムフォロア部材６およびカム部材１８を配置し、この直線方向の移動に対して相対的に移動するシリンダ本体９、ピストン１０およびピストンロッド１１を持つシリンダ部８から制動力を加えることを特徴としている。この構成によれば、当該回動に粘性流体からの制動力を加えるにも拘わらず、粘性流体の漏洩個所はピストンロッド１１の直線方向の摺動部となるので、Oリング程度の簡単なシール機構で済ますことができる安価なロータリダンパ装置を提供することができる。【選択図】図２
