ABSTRACT:
A slider of a miniature linear guide apparatus includes a race member having an inverted U-shaped cross section and ball rolling grooves formed in outer surfaces of side walls respectively corresponding to ball rolling grooves of a guide rail, and a ball guide member having a pair of ball return passages in the longitudinal direction and parallel to each other. The ball return passages of the ball guide member are formed in a groove form having upwardly directed openings. The openings are directly closed by an upper plate of the race member when the ball guide member is fitted into a U-shaped recess of the race member. The race member and the ball guide member are secured to each other by fitting protrusions formed on the upper surface of the ball guide member into fixing holes formed in the upper plate of the race member to form the slider.
