<p><P>PROBLEM TO BE SOLVED: To smoothly guide linear motion of an output member even when a lateral moment acts on the output member linearly moving, and release pressing force of a linear actuator even when an electric motor has a failure or the supply of electricity is stopped. <P>SOLUTION: A carrier 6 supporting a planetary roller 7 is regulated in movement in the axial direction. An outer ring member 5, which is fitted internally to the inner diameter face of a cylindrical part 1a of a housing 1 to be slidable in the axial direction, is locked to a driven object connected thereto with a key 22 so that the outer ring member 5 works as the outer member linearly moving. A hexagon socket 4a for a hexagon head wrench is provided in the end face of a rotating shaft 4 to allow the rotating shaft 4 to be manually rotatable. <P>COPYRIGHT: (C)2011,JPO&INPIT</p> |
