<P>PROBLEM TO BE SOLVED: To provide a remotely operated actuator which can change by remote operation the attitude of a tool mounted to the tip of an elongated pipe section and can accurately position the tip of the tool. <P>SOLUTION: The remotely operated actuator includes an elongated spindle guide section 3, a tip member 2 mounted to the tip of the spindle guide section in such a manner that the attitude of the tip member is changeable, and a drive section housing 4a to which the base end of the spindle guide section 3 is joined. The tip member 2 rotatably supports a spindle 13 for holding a tool 1. The spindle guide section 3 is provided with a rotating shaft 22 for transmitting rotation to the spindle 13 and also with an attitude operation member 31 for changing the attitude of the tip member 2, and the rotating shaft and the attitude operation member are provided within an outer shell pipe 25 which serves as the outer shell for the spindle guide section. The attitude operation member 31 is inserted through a guide hole 30a of a guide pipe 30 located within the outer shell pipe 25 so that the attitude operation member can advance and recede. The remotely operated actuator is also provided with a guide pipe restraining means 50 for preventing the guide pipe 30 from moving within the outer shell pipe 25. <P>COPYRIGHT: (C)2011,JPO&INPIT |
