Abstract
An electric linear actuator includes a fixed block, an output movable block, a counter movable block, a projecting side coupling member, a retracting side coupling member, a block coupling member, and an output functional member. The output movable block and the counter movable block are configured to be reciprocated in the movable direction in opposite phases by electromagnetic force acting between the fixed block and the output and counter movable blocks. The projecting side coupling member is coupled to the output movable block and the counter movable block. The retracting side coupling member is coupled to the output movable block and the counter movable block. The projecting side coupling member and the retracting side coupling member have different shapes.
