A guide apparatus has a standard end plate split into a pair of split parts that can be positioned with respect to each other with high accuracy and firmly secured to each axial end of a moving block body without fear of displacement during use. The guide apparatus has a moving block relatively movably attached to a track rail. The moving block body has in a section perpendicular to the axial direction a geometry that allows the moving block body to be assembled to the track rail at an intermediate part of the track rail. The end plate 24 consists essentially of a pair of split parts 24-1, 24-2 that are splittable to right and left in the width direction of the end plate. One split part 24-1 has a positioning pin 26 projecting from a parting surface thereof. A positioning hole 27 fittable with the positioning pin is provided in a parting surface of the other split part 24-2. The positioning pin is fitted into the positioning hole to form an end plate 24-2 assembly. The end plate assembly is secured to one end of the moving block body in the direction of relative movement by using securing screws 28-1, 28-2 passed through securing screw holes provided in the split parts 24-1, 24-2, respectively. |
