Claims

[Claims for Utility Model Registration] 1. A U-shaped axial groove that has two ball rolling grooves with an arcuate cross section on both sides, and the axes of symmetry in the cross section of the ball rolling grooves intersect with each other on the outside. Each has a raceway shaft formed on both sides of a rectangular cross section, and an axial ball transfer groove on the inner surface that is crowned by the raceway shaft and corresponds to the ball transfer groove of the raceway shaft, and the ball rolls on the inner surface. a slide table having through holes drilled behind the ball transfer grooves corresponding to the grooves and serving as return passages for the balls; A plurality of side plates having arc-shaped ball passages formed as recesses on one side surface forming ball circulation paths in the moving base, and between the ball rolling groove of the track base and the ball rolling groove of the sliding base. and a large number of balls disposed in the ball circulation path so as to be freely transferable. 2. The track according to claim 1, wherein the ball transfer groove of the track shaft has a groove bottom portion that intersects at right angles with a straight line parallel to the bottom surface of the track shaft in a cross section of the track shaft.
