PURPOSE:To improve control response property while compacting the device by internally setting up a phase-angle converter and a hydraulic piston directly operating the converter into an input shaft formed cylindrically. CONSTITUTION:A slider 4 and splines 3a, 4b, 4a, 2g forming the phase-angle converter converting the phase angle of an output shaft 3 and an operating piston 4e are mounted internally into the input shaft 2 formed cylindrically. In such constitution, the phase angle of the output shaft 3 is converted because the spline 3a forms a spline groove twisted in the oblique direction to the output shaft 3 when the slider 4 is moved by the piston 4e, but the piston 4e is shaped integrally with the slider 4, thus improving response property without generating play while forming axial length in short size. |
