ABSTRACT:
A linear guide apparatus comprises: a slider body having ball rolling grooves opposed to ball rolling grooves of a guide rail which are extended axially in parallel to each other; end caps secured respectively to both ends of the slider body, each end cap having a ball retainer locking portion in a joining surface which is in contact with the slider body; and a ball retainer having engaging portions which are engaged with the ball retainer locking portion of the end caps, and both side walls each of which defines with an edge of one of the ball rolling grooves of the slider body an opening which is slightly smaller than a diameter of rolling balls. The engaging portions are movably engaged with the ball retainer engaging portions of the end caps so that the ball retainer is movably held on the slider body. Thus, the apparatus is excellent in operability in which the balls are not excessively pushed by the ball retainer.
