Abstract

An actuator includes a fixed body and a movable body. The fixed body includes a first yoke, a pair of drive magnets overlapped so as to interpose the first yoke therebetween with their same polarities being directed to the first yoke, and a second yoke which faces an outer peripheral end face of the first yoke and is superposed on respective end faces positioned on the outer sides of the pair of the drive magnets. The movable body includes a coil disposed so as to surround around the outer peripheral end face of the first yoke between the first yoke and the second yoke and the coil is displaced in an axial direction by energization to the coil. The actuator may be preferably applied to a pump device.
