On the other hand, the movable member of the linear guide device slides on a linear guide rail of a considerably long length, and in particular, moves quickly and continuously in the X and Y axis directions on the guide rail during operation.

In addition, the movable member of the linear guide device frequently occurs while repeatedly performing the necessary work while staying at the same position for a long time, where the X and Y coordinate values of the corresponding mechanical device may be changed. As a result, the work result of the mechanical device becomes inaccurate, problems may arise in the dimensional stability and rigidity of the linear guide device, and the accuracy of the work decreases.

Therefore, it is urgent to prepare a solution that can prevent the coordinate value from changing when the necessary work is repeatedly performed at the same position.

An object of the present invention is to arrange the locking block and the locking cylinder interlocking between the slide support frame and the slide block of the linear guide device, thereby improving the adhesion between the slide support frame and the slide block can greatly improve the reliability of the work It is to provide a linear guide device.
