<p>Disclosed is a zero point position-determining mechanism for pressurized fluid-driven apparatuses, comprising an oil supply-adjusting knob (46) formed with an arrow-shaped recess (44) for indicating a zero point position, an insert member (66) for being internally fitted to a hole of the oil supply-adjusting knob (46), a stopper (74) for setting an assembled state of the oil supply-adjusting knob (46) and the insert member (66) to be at a zero point position, and a first spline section (78) and a second spline section (94) for being fitted to one another to determine the position so that the zero point position of the recess (44) corresponds to that of a holder (26). <IMAGE></p> |
