<p><P>PROBLEM TO BE SOLVED: To provide an electric linear motion actuator capable of smoothly guiding the linear movement of an output member performing linear movement even if a lateral moment acts to the output member, and shortening the length in an axial direction of the entire electric linear motion actuator. <P>SOLUTION: The movement of a carrier 6 for supporting a planet roller 7 is regulated in an axial direction, an outer ring member 5 internally fitted so as to be slidable in the axial direction to the inner diameter surface of a cylindrical portion 1a of a housing 1 is whirl-stopped by a key 25 to a driven object to be coupled, the outer ring member 5 is used as an output member for linear movement, a rotating shaft 4 is arranged in parallel to the rotor shaft 2a of the electric motor 2, and the rotation is transmitted from the rotor shaft 2a to the rotating shaft 4. <P>COPYRIGHT: (C)2011,JPO&INPIT</p> |
