To provide a passage opening and closing device with a long working life.SOLUTION: A passage opening and closing device includes a frame 50 having an air passage 52 formed therein, and a plate-like polymer actuator 60 fixed to the frame 50 and bent by application of a voltage to adjust the opening degree of the air passage 52. The polymer actuator 60 is fixed at an angle at which the opening degree of the air passage 52 changes in either of a case where the flat shape is bent to one side and a case where the flat shape is bent to the other side. According to this, when the air passage 52 is repeatedly opened and closed, both bending to the one side and bending to the other side of the polymer actuator 60 are repeated, such that the shape of the polymer actuator 60 is prevented from getting into a patterned shape, and the operating life can be extended.SELECTED DRAWING: Figure 2

    【課題】動作寿命の長い通路開閉装置を提供する。【解決手段】通路開閉装置は、空気通路52が形成された枠体50と、枠体50に固定され、電圧の印加により屈曲して空気通路52の開度を調整する板状の高分子アクチュエータ60と、を備える。高分子アクチュエータ60は、平坦な形状から一方側へ屈曲した場合と他方側へ屈曲した場合のいずれにおいても空気通路52の開度が変化する角度で固定されている。これによれば、空気通路52の開閉を繰り返すと、高分子アクチュエータ60の一方側への屈曲と他方側への屈曲の両方が繰り返されるので、高分子アクチュエータ60の形状に癖がつくことを抑制し、動作寿命を長くすることができる。【選択図】図2
