Abstract

A vehicle linear motor includes: a tubular casing; a pair of armatures placed and fixed in the casing; a mover formed in a flat plate shape and placed to face the pair of armatures and to be movable in the casing; and a support member configured to slidably support the mover such that the mover moves in a longitudinal direction of the mover. The mover formed in the flat plate shape includes a plurality of magnets that are arranged at intervals in the longitudinal direction. Each of the pair of armatures has a magnetic pole that is arranged to move the mover relative to the armatures in the longitudinal direction. The casing is mounted on a vehicle such that the longitudinal direction is a horizontal direction, and the mover and the armatures are placed to face each other in the horizontal direction.
