<p>In the present invention, a remote control operation portion 7 has a joystick 701 provided therein, whose position is sensed by a potentiometer 702. Further, the joystick 701 includes a gear 703, and engagement of the gear 703 with a gear 705 provided in a rotation axis of a servo motor 704 allows the joystick 701 to be moved by a drive force of the servo motor 704. Further, the remote control operation portion 7 includes a drive/communication portion 706 which detects position information of the potentiometer 702, drives the servo motor 704, and is capable of communicating with a control portion 37. Such a configuration allows the position of the joystick to be easily adjusted in response to a bending state even if switching between a drive force transmission disconnected state and a drive force transmission recovered state is carried out by using a clutch mechanism.</p> |
