<p><P>PROBLEM TO BE SOLVED: To implement an irreversible device which prevents back drive torque in both forward and reverse rotation directions from being transmitted, with a simple construction. <P>SOLUTION: The irreversible device is provided with an output side actuating member 3 to engage with an output shaft 2 via a screw feed mechanism, the output side actuating member 3 is displaced in the axis line A direction when the back drive torque is applied to the output shaft 2, and a frictional brake 4 is provided to function through the displacement of the output side actuating member 3 so as to prevent the back drive. <P>COPYRIGHT: (C)2008,JPO&INPIT</p> |
