<P>PROBLEM TO BE SOLVED: To provide a remote-controlled actuator capable of remotely changing the posture of a tool attached to the distal end of a slender pipe part and having high rigidity in the pipe part. Ž<P>SOLUTION: The remote-controlled actuator includes: a slender-shaped spindle guide part 3; a distal end member 2 attached to the distal end of the spindle guide part in such a way that the posture can be freely changed; and a driving part housing with which the proximal end of the spindle guide part 3 is coupled. The distal end member 2 rotatably supports a spindle 13 for holding the tool 1. The spindle guide part 3 includes: a shell pipe 25; a rotating shaft 22 for transmitting the rotation of a tool rotating drive source within the driving part housing to the spindle 13; and a hollow guide pipe 30 penetrating both ends. A posture control member 31 for changing the posture of the distal end member 2 is inserted into the guide pipe 30, and a posture changing drive source is disposed within the driving part housing. The actuator also has a pipe fixing part 70 to fix the shell pipe 25 and the guide pipe 30. Ž<P>COPYRIGHT: (C)2010,JPO&INPIT Ž
