Abstract

A fault detection sensor-equipped actuator is provided which can easily detect a fault in at least one of a linear guide unit and a ball screw unit, using a shared sensor. In an actuator () including a linear guide unit () that guides linear movement of a movable body () and a ball screw unit () that drives the movable body () in an axial direction of a screw shaft (), a sensor () configured to detect a fault in the actuator () is placed in a housing () where a coupling () that couples the screw shaft () and a motor () for rotating the screw shaft () is housed.
