Abstract
A positioning control device having a moving body engaged with a screw shaft to be moved with the rotation of the screw shaft, and a rest bar for fixing the moving body having two long positioning retainers extending in the axial direction of the screw shaft makes it possible to securely hold a guide apparatus for rolling stock. The moving body is provided on its upper portion with a shift base for mounting the guide apparatus thereon, and on its lower portion with a shift bracket. A pair of hydraulic cylinders piercing through the shift bracket are opposed to each other across the screw shaft. A piston rod in each hydraulic cylinder is movable vertically so as to come into contact with the lower surface of the retaining portion of the rest bar. Both positioning retainers are secured on the retaining portion of the rest bar and disposed opposite to each other across the piston rods and the retaining portion of the rest bar so as to come into contact with the contact members of the shift base.
