-11099). What these prior technologies have in common is that
In order to mechanically drive the flap, which is attached to the tail end of the main rudder with a hinge so that it can turn freely, by the movement of the main rudder, the flap drive on the hull side has a pivot on the hull behind the rudder shaft. A structure is adopted in which the member and a flap driving member provided on the upper surface of the flap are joined by a sliding structure that is exposed to seawater.

Therefore, as a means of absorbing changes in the distance between the rotation center of the flap drive member on the hull side and the rotation center of the flap, a sliding structure that has a relationship like a piston and cylinder is generally adopted. The flap drive member on the flap side is joined.

The lower end of the vertical link 7 connected to the upper surface of the flap 3 by a pin is located closer to the rudder shaft 1, and the main rudder 2 and the flap 3 form a straight line. On the other hand, as shown in Fig. 3, at the position where the steering angle is the maximum, the pivot 5
The distance between the center of rotation of the flap and the flap rotation center is the longest, and the lower end of the vertical link 7, which is pin-connected to the upper surface of the flap 3, is at the farthest position from the rudder shaft 1, and the horizontal link 6 and vertical link 7 are extended to the main rudder 1. In contrast, the flap 3 is tilted significantly.
