Title:
SLIDE RAIL, LINEAR MOTION GUIDE DEVICE, AND MOVEMENT BODY FOR LINEAR MOTION GUIDE DEVICE
Document Type and Number:
WIPO Patent Application WO/2012/002041
Kind Code:
A1
Abstract:
A slide rail is configured so as to be simple and at the same time so as to allow an inner rail to move smoothly.
A second rail (2) is provided with a pair of opposing inner surfaces, and longitudinally extending rolling sections (6, 7) are formed respectively on the pair of inner surfaces. A first rail (1) is provided with: a first wheel (31) provided so as to be rotatable about a first axis; a second wheel (32) provided so as to be rotatable about a second axis which is separated from the first axis in the direction of movement of the first rail (1) so that the second wheel (32) does not make contact with the first wheel (31); and a rolling body (33) in contact with the first wheel (31) and with the second wheel (32) in such a manner that the rolling body (33) can rotate in association with the rotation of the first wheel (31) and of the second wheel (32). The first wheel (31) and the second wheel (32) perform rolling motion on the rolling section (7) of one of the inner surfaces of the second rail (2). The rolling body (33) performs a rolling motion on the rolling section (6) of the other inner surface of the second rail (2).
