This steering gear is provided with a rudder shaft gear (2), a fixed shaft gear (4) fixed to the end of a fixed shaft (3) which is disposed to have the same axis as the steering gear (1) and fixed to the hull, a carrier (5) arranged capable of rotating around the fixed shaft (3), a driving gear (6c) which rotates the carrier (5), and a drive source (6a) which drives the drive gear (6c). The carrier (5) has multiple planetary shafts (30a, 30b), and each of the multiple planetary shafts (30a, 30b) rotatably supports a planetary gear (10a, 10b) which meshes with the fixed shaft gear (4) and a planetary gear (20a, 20b) which meshes with the rudder shaft gear (2), and the working pitch diameter of the rudder shaft gear (2) with which the planetary gears (20a, 20b) mesh is different from the working pitch diameter of the fixed shaft gear (4) with which the planetary gears (10a, 10b) mesh. |
