ABSTRACT:
An actuator using a fluid cylinder in which rigidity may be attained with a simple configuration, includes a fluid cylinder, a first choke valve device, and a second choke valve device. The first choke valve device is disposed between a fluid pressure source and a first chamber, and the second choke valve device is disposed between the fluid pressure source and a second chamber. An opening of a valve of a discharge valve mechanism included in each of the choke valve devices is set so as to be in inverse proportion to a target pressure in the chamber in which the fluid pressure is adjusted by the choke valve device.
