ACTUATOR

Japanese Patent JP2017111772

A

PROBLEM TO BE SOLVED: To provide an actuator that is driven in accordance with requested responsiveness.SOLUTION: An actuator 1 includes an actuator unit Ui (i is a natural number) that is discretionary one included in a plurality of actuators, and an actuator unit Uj (j is a natural number different from i). The actuator units Ui, Uj are provided between a tabular member 11 and a tabular member 12. The actuator unit Ui includes actuator fiber Ti, p (p is a natural number) that is one actuator fiber in one or a plurality of fibers, and the actuator unit Uj includes actuator fiber Tj, q (q is a natural number different from p) that is one actuator fiber in one or a plurality of fibers. The sectional area of fiber Si, p of a high polymer fiber material included in the actuator fiber Ti, p and the sectional area of fiber Sj, q of a high polymer fiber material included in the actuator fiber Tj, q have the relationship Si, p
