DAMPER MEMBER AND ACTUATOR

To make a damper member hardly broken when stress is concentrated on an inner peripheral portion of a gel member, in the damper member constituted by connecting frame-shaped first member and second member by the cylindrical gel member.SOLUTION: An actuator 1 includes a damper member 10 for connecting a movable body 3 and a fixed body 2. The damper member 10 includes a first member 11, a second member 12 surrounding an outer peripheral side of the first member 11, and a cylindrical gel member 14 disposed between the first member 11 and the second member 12. The first member 11 includes an outer peripheral surface 150 to which an inner peripheral portion of the gel member 14 is connected. As an angle θ between a first gel end face 141 and the outer peripheral surface 150 of the first member 11 is 90° or more, the gel member 14 hardly separates from the outer peripheral surface 150 of the first member 11 when stress is applied to the inner peripheral portion of the gel member 14. Accordingly, the damper member 10 is hardly broken.SELECTED DRAWING: Figure 4 【課題】枠状の第１部材と第２部材を筒状のゲル状部材によって接続したダンパー部材において、ゲル状部材の内周部に応力が集中したときにダンパー部材を壊れにくくする。【解決手段】アクチュエータ１は、可動体３と固定体２とを接続するダンパー部材１０を備える。ダンパー部材１０は、第１部材１１、および第１部材１１の外周側を囲む第２部材１２と、第１部材１１と第２部材１２の間に配置される円筒形状のゲル状部材１４を備える。第１部材１１は、ゲル状部材１４の内周部が接続される外周面１５０を備える。第１ゲル端面１４１と第１部材１１の外周面１５０とのなす角度θが９０°以上であるため、ゲル状部材１４の内周部に応力が加わったときにゲル状部材１４が第１部材１１の外周面１５０からはがれにくい。従って、ダンパー部材１０が壊れにくい。【選択図】図４
