Claims

[Scope of utility model registration request]

A hydraulic device that hydraulically rotates a rudder in a ship, a main hydraulic system that supplies pressure oil to the hydraulic device to control the rudder angle of the rudder, and a main power source that drives an electric pump in the main hydraulic system; In a steering gear equipped with an auxiliary power source that can assist when the main power source stops, the steering angle of the rudder is controlled between when the main power source stops and when the auxiliary power source is switched. In order to achieve this, an auxiliary hydraulic system for supplying pressure oil to the above-mentioned hydraulic equipment is provided, a pressure accumulator for forming hydraulic pressure in the auxiliary hydraulic system, and a supply of pressure oil sent from the upper auxiliary hydraulic system to the above-mentioned hydraulic equipment. and a control valve that controls the stoppage, a first sensor that detects the stop state of the main power source, a second sensor that detects the completion of switching to the auxiliary power source, and a detection signal from the first sensor. control means for enabling the control valve to control the auxiliary hydraulic system based on the detection signal from the second sensor, and for disabling the auxiliary hydraulic system in C) based on the detection signal from the second sensor. An emergency auxiliary steering device.
