Abstract

[Object] To provide a compact, high-output actuator device allowing force control. [Solution] An actuator deviceincludes an electromagnetic coil memberprovided over a prescribed width on an outer circumference of a cylinder, and a movable elementslidable as a piston in the cylinder. The movable elementhas a magnetic member, and is moved relatively by excitation of the electromagnetic coil member. Fluid is supplied to first and second chambersandsuch that when the movable elementis to be moved relatively, the movable elementis driven in the same direction.
