ABSTRACT:
A miniature linear guide apparatus includes a guide rail having a U-shaped cross section, and a slider movable in the longitudinal direction of the guide rail supported by balls inserted in ball rolling channels formed between each of the inner surfaces of side walls of the guide rail and each of the outer surfaces of the sides of the slider. The slider includes two ball guide members respectively having ball passage arranged parallel to each other and parallel to the ball rolling channels. Each of the ball passages has curved ball passages at opposite ends of the ball passage to connect corresponding ends of the ball rolling channel and the ball passage thereby to constitute a circulating path for the balls through the ball rolling channel passage, the curved passages, and the ball passages.
