<p>An electric linear motion actuator is provided which can set the clearance during normal braking operation of an electric brake system. The linear motion actuator includes a load sensor (14) for detecting the magnitude of the load with which a friction pad (7) is pressed against the brake disk (2), a temperature sensor (37) for compensating for the influence of temperature on the load sensor (4), and an electronic control unit (50). The electronic control unit (50) is adapted to calculate a target rotational angle (¸) from the position of the electric motor (15) corresponding to the magnitude of the load detected by the load sensor (4) to the position of the electric motor (15) where the clearance is at a predetermined value, and control the electric motor (15) to rotate the electric motor (15) by the target rotational angle (¸).</p> |
