えるようになっている。(Prior Art) A linear guide device includes a rail extending in the axial direction, a saddle-shaped bearing placed over the rail, and a large number of balls interposed between opposing parts of the rail and the bearing. By rolling, the bearing can slide smoothly on the rail. However, since the sliding resistance of the bearing is very small, it is sometimes difficult to stop the bearing at a desired position, and for this reason, a bearing braking means is sometimes provided between the bearing and the rail. As a conventionally used braking means, there is one in which a recess is formed in the inner surface of a bearing and a spring and a friction member are installed in the recess (for example, as disclosed in Utility Model Application No. 56-99555 filed by the present applicant). ). The friction member is pressed against the rail by the action of the spring, applying braking force to the bearing.
