PROBLEM TO BE SOLVED: To provide a remote-controlled actuator capable of changing the posture of a tool attached at the distal end of a slender pipe by the remote-control, and easily changing the posture of the tool by the operation at hand.SOLUTION: The remote-controlled actuator includes a slender spindle guide 3, a distal-end member 2 attached at the distal end of the spindle guide in such a way that the posture can be changed, and a drive part housing 4a to which the proximal end of the spindle guide 3 is coupled and which can be held by hand. The distal-end member 2 rotatably supports a spindle 13 holding the tool 1. The spindle guide 3 includes a rotating shaft 22 for transmitting the rotation to the spindle 13, and a posture operating member 31 for changing the posture of the distal-end member 2 by the forward/backward movement within a guide hole 30a. The posture operating member 31 is moved forward/backward by a posture changing drive source. A posture changing operation implement 53 for outputting a motion command signal to the posture changing drive source is mounted outside the drive part housing 4a. The posture changing operation implement 53 permits the input operation by a hand holding the drive part housing 4a.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遠隔操作で変更することができ、その工具の姿勢変更を手元操作で容易に行え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、スピンドルガイド部3の基端が結合され手により保持可能な駆動部ハウジング4a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に回転を伝達する回転軸22と、ガイド孔30a内を進退して先端部材2の姿勢を変更させる姿勢操作部材31とを有する。姿勢操作部材31は、姿勢変更用駆動源で進退させる。この姿勢変更用駆動源に動作指令信号を出す姿勢変更操作具53を、駆動部ハウジング4aの外部に設ける。姿勢変更操作具53は、駆動部ハウジング4aを保持する手で入力操作可能とする。【選択図】 図1
