Claims

[Claims for Utility Model Registration] An extended guide rail with axial rolling element rolling grooves on both sides, and a rolling element of the guide rail that is loosely fitted onto the guide rail so as to be relatively movable in the axial direction. A linear guide device including a slider having a rolling groove on an inner surface facing the rolling groove and a circulation path for the rolling element rolling in the rolling groove, and a slider having an axial direction on both sides of the protrusion. a ball spline shaft having a plurality of protrusions protruding from the outer surface in which ball spline grooves are formed; and an axial ball rolling groove at a position opposite to the ball spline groove of the ball spline shaft; A retainer having a circulation path for balls rolling therein and loosely fitted to the ball spline shaft, and an outer cylindrical body supporting the ball spline shaft via the balls held in the retainer. A linear guide/ball spline integrated device is formed by integrating a ball spline device such that the axes of both devices are perpendicular to each other. A linear guide/ball spline integrated device, characterized in that it constitutes an outer cylinder of the ball spline device.
