PROBLEM TO BE SOLVED: To provide a steering gear enabling high turning performance/maneuvering performance or emergency braking.SOLUTION: A ship steering gear 1 includes a steering shaft 40 having a main rudder connected and drooped from a rudder plate upper part to be held by a hull rotatably around a vertical axis, a driving mechanism 601 for rotating the steering shaft around the vertical axis, and a power mechanism for driving the driving mechanism, and is characterized in that the driving mechanism includes an input node having a fulcrum which is a first rotation center 504 bound to the hull, the input node 506 includes an input junction point 521 rotatably linked with a junction rod 520 of the reciprocating power mechanism to receive a turning force around the fulcrum, and a speed increase link mechanism is provided to enable increased-speed rotation of the main rudder around the steering shaft with the steering shaft set as a fulcrum which is a second rotation center 505 and a steering handle 500 connected to the fulcrum and set as an output node.SELECTED DRAWING: Figure 3 |
