Disclosed is a continuous position control apparatus comprising a hydraulic control portion(B) which includes a direction change valve(43) to select oil pressure transferred from a high pressure hydraulic line and a low pressure hydraulic line by a control means and a position detecting means, and a variable portion(A) which can move from side to side a movable core(3) when moving plungers(9,10,11,12,52,53) after high pressure is sequentially input into a plurality of input rooms(18,19,20,21,50,51) attached to both sides of chambers(7) by the difference of selection oil pressure supplied to both sides of a piston(30) aligned to a path(13) formed in the center of the movable core(3) and the selection oil pressure input into left and right hydraulic rooms(4a,4b) isolated by the outward flange(5) of the movable core(3).
