Abstract
In a miniature linear guide device providing: an axially extending guide rail U-shaped in section, the guide rail including a load ball rolling groove formed on an inner surface of a side wall of the guide rail, a slider body U-shaped in section which is fitted in the side wall of the guide rail, the slider body including a load ball rolling groove formed on an outer surface of a side wall of the slider body and confronted with the load ball rolling groove of the guide rail; a circulator fitted in the slider body and including a non-load ball circulating path; and a plurality of balls rolling between the load ball rolling grooves and the non-load ball circulating path, the guide rail includes a rail mounting portion formed by cutting a portion of a bottom of the guide rail and bending the portion outward in a width direction so as to be opened apart outward from the side wall. Further, the circulator includes a recess formed in a middle portion of a longitudinal end of the circulator for accommodating a head of a rail mounting screw fixing an end of the guide rail to a base. The rail fastening force can be increased with ease by increasing the size and number of rail mounting screws. The height of the linear guide device can be lowered.
