PROBLEM TO BE SOLVED: To provide a remote-controlled actuator surely changing by remote control operation the attitude of a tool mounted to the distal end of an elongated pipe section.SOLUTION: This remote-controlled actuator includes: an elongated-shaped spindle guide section 3, a distal end member 2 mounted to its distal end such that its attitude is changeable a tool 1 rotatably mounted to the distal end member 2 a driving source for tool rotation, rotating the tool 1 and a driving source for attitude change, operating the attitude of the distal end member 2. The distal end member 2 rotatably supports a spindle 13 for holding the tool 1. The spindle guide section 3 has, in its inside, a rotating shaft 22 for the spindle 13, and an attitude operating member 31 inserted into a guide hole 30a so as to freely move forward and backward and changing the attitude of the distal end member 2. The driving source for attitude change is a rotary actuator, and the rotary actuator rotates the base end of the attitude operating member 31 to forward and backward move the attitude operating member 31 by the operation of a screw mechanism 36.COPYRIGHT: (C)2010,JPO&INPIT【課題】 細長いパイプ部の先端に設けられた工具の姿勢を確実に遠隔操作で変更することができる遠隔操作型アクチュエータを提供する。【解決手段】 細長形状のスピンドルガイド部3と、その先端に姿勢変更自在に取付けられた先端部材2と、先端部材2に回転自在に設けた工具1と、工具1を回転させる工具回転用駆動源と、先端部材2の姿勢を操作する姿勢変更用駆動源とを備える。先端部材2は、工具1を保持するスピンドル13を回転自在に支持する。スピンドルガイド部3は、スピンドル13用の回転軸22と、ガイド孔30a内に進退自在に挿通され、先端部材2を姿勢変更させる姿勢操作部材31とを内部に有する。姿勢変更用駆動源はロータリアクチュエータであって、このロータリアクチュエータで姿勢操作部材31の基端を回転させることにより、ねじ機構36の作用で姿勢操作部材31を進退させる。【選択図】 図2
