Claims

[Scope of utility model registration request]

In a fully hydraulic power steering device including a hydraulic circuit connecting a steering unit operated by a steering wheel and a steering cylinder that deflects the vehicle body, a sensor detects a steering wheel rotation angle; a sensor detects a vehicle body deflection angle;
A steering wheel position correction device for a fully hydraulic steering system, comprising: a controller that compares and processes the outputs of these two sensors and drives a steering wheel position deviation correction solenoid valve according to the output difference;
