<p>PROBLEM TO BE SOLVED: To provide a valve device capable of achieving reduction in size, reduction in weight and low cost.SOLUTION: A valve device 1 drives a valve body 31 via an operation member 33 by expansion deformation of a contraction type polymer gel actuator 10. A direction in which the operation member 33 moves forward and backward is a direction orthogonal to a direction in which a cathode plate 11 and an anode plate 13 move forward and backward, and between the cathode plate 11, the anode plate 13 and the operation member 33, power transmission parts 41, 43 are provided for converting the forward and backward movement of the cathode plate 11 and the anode plate 13 into the forward and backward movement of the operation member 33 and transmitting it. When the cathode plate 11 and the anode plate 13 move in an approaching direction by application of a voltage to the polymer gel actuator 10, the operation member 33 is pushed toward the valve body 31 side via the power transmission parts 41, 43.</p> |
