PURPOSE: To improve displacement efficiency by reducing the number of stocks using a displacement variable pump having one kind of structure and making intensive a number of sizes by means of a manual adjustment and a dead volume between a piston and a cylinder hole during the low inclined rotation of a cylinder block. CONSTITUTION: In a valve plate spherically brought into contact with the end of the cylinder head side of a cylinder block, a projecting circular arc surface is formed in a side opposite the cylinder block and supported in the recessed circular arc surface of a cover fixed to a housing. The center axial line 44 of this projecting circular arc surface includes the axial line 13 of a rotary shaft and the axial line 15 of a cylinder block 11, and within one plane in which an incline rotation angle is changed, this is decided in a position shifted from the axial line of the rotary shaft in the inclined rotational direction of the cylinder block. The tip part 52 of a screw rod 51 is brought into contact with the inclined rotational direction downstream side end of the valve plate and the valve plate is positioned and adjusted.
