Claims

[Claims for Utility Model Registration] (1) A guide rail having rolling element rolling grooves extending parallel to each other in the axial direction at symmetrical positions on the side surface, and a rolling element rolling groove facing the rolling element rolling grooves of the guide rail. A linear guide device comprising: a slider having a moving groove; and a large number of rolling elements interposed in a rolling element rolling path composed of a rolling element rolling groove of the guide rail and a rolling element rolling groove of the slider. In the slider, a retainer is disposed on the slider to hold the movable body disposed in the rolling element rolling path, and the retainer is configured by laminating a metal plate and a vibration isolating material. A linear guide device characterized by: (2) The linear guide device according to claim 1, wherein the retainer has a three-layer structure in which the buffer material is sandwiched between two metal plates. (3) The retainer has an elongated hole for holding the rolling element, and raised portions are formed at both ends of the elongated hole to raise the rolling element so that its outer locus of movement forms an arc. A linear guide device according to claim 1 or 2 of the utility model registration claim. (4) The retainer has a long hole for holding the rolling element, and raised portions are formed at both ends of the long hole to raise the rolling element so that its outer movement locus becomes an arc shape. The slider has a curved rolling element passage that communicates with both ends of the rolling element rolling path, and a rolling element return passage that communicates between the curved rolling element passages,
A tongue piece to be inserted into the rolling element rolling groove of the guide rail is formed in a communication portion of the curved rolling element passage with the rolling element rolling path, and the tongue piece is inserted into the rolling element rolling groove raised by the raised part. Utility model registration claim No. 1, which has a circular arc portion connected to the outer locus of movement of the moving body and a straight line portion extending in the tangential direction of the outer locus from the contact point where the rolling element of the arc portion first abuts. 1
Linear guide device described in section.
