Abstract

See full text

A linear actuator may include a movable element having a plurality of permanent magnets stacked in a direction of an axis line; a stationary element comprising a plurality of coils surrounding a circumferential section of the permanent magnets, the plurality of coils being placed along the axis line; and viscous elastic members inserted between the movable element and the stationary element. The plurality of permanent magnets are arranged such that, among adjacent permanent magnets of the plurality of permanent magnets, sides of the adjacent permanent magnets facing each other have a same polarity. The viscous elastic members are provided at a plurality of locations being separate in the direction of the axis line, in a space sandwiched in a radial direction by the movable element and the stationary element.
