PURPOSE:Not to generate large torque at steering and to dispense with a large space by connecting the column of a handle to the input shaft of a hydraulic actuation device, and connecting a pair of controlling ports to a front wheel steering cylinder. CONSTITUTION:An inlet port 7, an output port 8, and a pair of controlling ports are provided in a housing 6, and a changeover valve 9 is rotatably arranged in a center hole. A measuring part 19 is provided with an internal gear member 21 and an external gear member 22 which is eccentrically provided in the internal gear member 21 and autorotation and revolution are performed, and the spline 23 of the external gear member 22 is engaged with the spline of a first drive shaft 17. On the inside of an output shaft 24, a spline 26 is provided, and a second drive shaft 27 engaged with the splines 23,26 is provided. Because the output shaft 24 is connected to the external gear member 22 of the measuring part through the second drive shaft 27, autorotation of the external gear member 22 is picked up with the output shaft 24, and rotation of the output shaft 24 is transmitted to a front wheel steering device through a connecting member 4. |
