Claims

[Claims for Utility Model Registration] (1) An extended guide rail with axial rolling grooves on both sides, and a guide rail that is movably loosely fitted onto the guide rail and that allows the guide rail to rotate. A slider body having a rolling element rolling groove opposite to the rolling element rolling groove on the inner surface and a rolling element return passage parallel to this within the wall thickness, and the rolling element return passage and the rolling element rolling groove are communicated with each other. An end cap having a rolling element circulation path curved in a semi-circular arc shape and joined to the end of the slider body fits into both of the opposing rolling element rolling grooves, the rolling element return passage and the rolling element circulation path. In the linear guide device, the guide rail is provided independently on each side and has an outer plate made of a metal plate with rolling grooves formed on the outer surface thereof. , an elastic filling member filled between the outer plates, and the guide rail is capable of freely bending laterally. (2) An extended guide rail with axial rolling element rolling grooves on both sides, and a roller that is movably loosely fitted onto the guide rail and faces the rolling element rolling groove of the guide rail. A slider main body having a rolling element rolling groove on its inner surface and a rolling element return passage parallel to this within its wall thickness, and a rolling element curved in a semicircular arc shape that communicates the rolling element return passage with the rolling element rolling groove. An end cap having a circulation path and joined to the end of the slider body, and fitted into the opposing rolling element rolling grooves, the rolling element return passage, and the rolling element circulation path, and are arranged so as to be able to freely roll. In a linear guide device equipped with a large number of rolling elements, the slider has an inner plate made of a metal plate integrally formed with a rolling element rolling groove on the inner surface thereof and a retainer for holding the rolling element in the groove. A linear guide device comprising: an elastic filling member closely attached to the outer periphery of the inner plate. (3) An extended guide rail with axial rolling element rolling grooves on both sides, and a roller that is movably loosely fitted onto the guide rail and faces the rolling element rolling groove of the guide rail. A slider main body having a rolling element rolling groove on its inner surface and a rolling element return passage parallel to this within its wall thickness, and a rolling element curved in a semicircular arc shape that communicates the rolling element return passage with the rolling element rolling groove. An end cap having a circulation path and joined to the end of the slider body, and fitted into the opposing rolling element rolling grooves, the rolling element return passage, and the rolling element circulation path, and are arranged so as to be able to freely roll. In a linear guide device equipped with a large number of rolling elements, the guide rail is formed with a rolling groove for the rolling elements, can be freely curved laterally, and is made of a metal plate provided independently on each side. an outer plate,
and an elastic filling member filled between the outer plates, and the slider is made of a metal plate integrally formed with a rolling element rolling groove on the inner surface thereof and a retainer for holding the rolling element in the groove. A linear guide device comprising: an inner plate; and an elastic filling member closely attached to the outer periphery of the inner plate.
