<p>A remote operation actuator which can, by means of remote operation and with good accuracy, change the attitude of a work device provided to the front end of a curved elongated guide section and which is configured so that a compact drive source serves the purpose of changing the attitude of the work device. A remote operation actuator is provided with a curved elongated guide section (3), a front end member (2) which is mounted to the front end of the guide section (3) in such a manner that the attitude of the front end member (2) is changeable, and a work device (1) which is provided to the front end member (2). The guide section (3) is provided therewithin with a drive shaft (22) which transmits to the work device (1) the driving power of the drive source (41) for the work device, and with a guide hole (30a) which is curved and penetrates through to the opposite ends of the guide section (3). A wire-like attitude operation member (31) for changing the attitude of the front end member (2), which is advanced and retracted by being driven by the drive source (42) for attitude change, is inserted through the inside of the guide hole (30a) so as to be able to advance and retract. When in a natural state, that is, when not being inserted in the guide hole (30a), the attitude operation member (31) has the same curved shape as the guide hole (30a).</p> |
