A remote-controlled actuator capable of reliably changing by remote control operation the attitude of a tool mounted to the front end of an elongated pipe section. A remote-controlled actuator is provided with an elongated-shaped spindle guide section (3), a front end member (2) mounted to the front end of the spindle guide section (3) through a front-end-member connecting section (15) such that the attitude of the front end member (2) is changeable, a tool (1) rotatably mounted to the front 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 front end member (2). The front end member (2) rotatably supports a spindle (13) for holding the tool (1). Inside the spindle guide section (3), there are provided a rotating shaft (22) for transmitting rotation of the driving source for tool rotation to the spindle (13) and also a guide hole (30a) penetrating through to opposite ends of the spindle guide section (3). An attitude operating member (31) having flexibility is inserted through the guide hole (30a) so as to be able to be advanced and retracted. The attitude operating member (31) has a front end which, while being in contact with the front end member (2), is advanced and retracted to change the attitude of the front end member (2). The attitude operating member (31) is advanced and retracted by the driving source for attitude change. |
