ACTUATOR DRIVE DEVICE BY OPERATION LEVER AND OPERATION LEVER DEVICE

摘要

PROBLEM TO BE SOLVED: To simplify the structure of an actuator drive device. SOLUTION: Four pistons 1, 2, 3, 4 are respectively corresponded to one of two kinds of actuators 35, 37, and its drive direction (forward direction or backward direction). An actuator corresponding to the piston on which a displacement signal is generated, is driven in the corresponding drive direction by a drive amount corresponding to the displacement signal, when the displacement signal is generated to respectively four pistons 1, 2, 3, 4 by the displacement signal generating means 20, 19, 21, 18.
