とを特徴とする位置割出装置。 A flow control valve 14 having a variable orifice 17 is interposed in a discharge line 21 or a tank line 22 connected to the drive motor 1 that drives the indexed object, and the variable orifice 17 closes at the index position and The position indexing device is configured to cause the variable orifice 17 to respond to the rotational position of the drive motor 1 so that the rotation speed of the drive motor 1 is reduced to a small opening in the vicinity of the indexed position, A first pressure-compensated flow control valve 31 having a flow rate set value higher than the flow rate corresponding to the small opening degree is interposed in the discharge line 21 or the tank line 22, and further the first pressure-compensated flow control valve 31 A series circuit of the second pressure-compensated flow control valve 35 and the switching valve 34 is connected in parallel to the variable orifice. 17. A position indexing device characterized in that the flow rate is less than or equal to the allowable flow rate when fully opened.
