ABSTRACT:
The present invention relates to a slider of a linear guide device for guiding a movable body such as a work table or an industrial robot or the like of a machine tool under load which moves along a track rail arranged at a fixed portion such as a bed, or a column. The block main body is made of a metal which becomes a core part of the slider in a predetermined shape and forming load rolling faces of balls on the block main body by machine. The block main body is inserted into a mold and injection molding of a synthetic resin is performed by which ball retaining portions are built on both sides of the load rolling faces of block main body. Pairs of smooth faces for shielding the molten synthetic resin are formed along the both edges in the longitudinal direction of the load rolling faces formed on block main body whereas the block main body is fixed at a predetermined position in the mold by bringing a projected support portion on the side of the mold into contact with the smooth faces for shielding the molten synthetic resin.
