PURPOSE:To make space necessary to steering small by providing a control stick free in angular displacement from right to left so as to steer the boat by the angular displacement of this control stick. CONSTITUTION:A control stick 35 is provided in angular displacement free on right and left, and steering can be performed by means of grasping the control stick 35 by one hand and oscillating it. With this arrangement, the control stick 35 can be operated in small space. In addition, steering is performed by means of angle-displacing the control stick 35 on right and left, and thereby the steering direction can be known by the angular displacement direction of the control stick 35. |
