<P>PROBLEM TO BE SOLVED: To provide a remote-controlled actuator that changes the position of a tool attached to the end of an elongated pipe with high dimensional accuracy via its remote controlled operation. <P>SOLUTION: The actuator includes an elongated spindle guide 3, an end part 2 attached to the tip of the same while the attached end part 2 easily changes its position, and a tool 1 rotatably provided at the end part 2. The spindle guide 3 includes a rotation shaft 22 to transmit rotation to the spindle 13, and a guide hole 30a opened throughout both the ends of the same. A positional change drive source 42 moves forward and backward a positional operation member 31 inserted, with its position being variable, through the guide hole 30a to change the position of the end part 2. When a positional control means 53 to control the position of the positional change drive source 42 takes control of the positional operation member 31 over its movement from the standard operation start position to the target position, the process includes a step where the position operation member is temporarily moved away from the target position. <P>COPYRIGHT: (C)2012,JPO&INPIT |
