Abstract
In a linear guide apparatus provided with a guide rail, a slider, an end cap, a plurality of balls and a ball retainer, the end cap includes a half-ring-shaped curved path in the inner surface and an outer peripheral groove, in the outer surface, which is curved in correspondence to the curved path, the outer peripheral groove having a side wall and protrusions which extend from the side wall so as to decrease the width of the outer peripheral groove, the ball retainer being secured to the slider with a locking part of the ball retainer which is engaged with the outer peripheral groove while being held between the protrusions. The ball retainer is so improved that it can be readily secured to the slider of the linear guide apparatus without interfering with other components, and readily so absorbs a dimensional difference relative to the slider that it prevents the rolling balls from falling away from the slider.
