Abstract
A linear actuator includes a guide rail, a wall portion, a coil, a heat transfer member, a heat radiation member, and a heat insulation member. A mover having a permanent magnet is movable along the guide rail. The wall portion is installed on a pedestal and supports the guide rail. The heat transfer member is coupled to the coil and the heat radiation member is coupled to an end of the heat transfer member. The heat insulation member is installed on the pedestal and coupled to the heat radiation member. The heat transfer member is arranged apart from the wall portion.
