Claims

[Scope of utility model registration request]

An extended guide rail having axial rolling element rolling grooves on both sides, and a slider loosely fitted to the guide rail so as to be movable in the axial direction, the slider having a rolling groove in the guide rail. A slider body having a rolling element rolling groove opposite to the rolling groove on the inner surface and a rolling element return passage parallel to the rolling element return passage within the wall thickness; an end cap having a curved path curved in a semicircular arc shape communicating with the moving body rolling groove;
Two series of rolling element rolling grooves are provided in parallel on the guide rail, and the slider is loosely fitted in each series of the two series of rolling element rolling grooves with vertically opposite phases, and the slider is loosely fitted in each series of the two series of rolling element rolling grooves in opposite phases. A double linear guide device characterized in that the double linear guide device is configured to be movable independently through the rolling motion of a large number of rolling elements inserted into a moving element rolling groove.
