Claims

[Claims for Utility Model Registration] (1) A rail made of a metal member that has a U-shaped cross section and has ball rolling grooves in the axial direction formed on the inner surfaces of opposing side walls, and a ball rolling groove in the rail. A slider having ball rolling grooves on the outer surface facing each of the moving grooves and having a ball circulation passage connected to the ball rolling grooves formed inside, and a ball rolling groove of the slider and the ball rolling of the rail. In the miniature linear guide device, the slider has a cross-sectional core having ball rolling grooves on both outer surfaces thereof, which are opposite to the ball rolling grooves of the rail. A race member made of a metal member in the shape of a letter, and a collar portion provided at both ends with a protrusion that fits into a ball rolling groove of the rail and is close to the ball rolling groove, and is provided in a U-shaped recess of the race member. The slider body is composed of a synthetic resin slider body having a body part in the middle which is fitted into the slider body, and the slider body has an inner circular arc surface that is continuous with the ball rolling groove of the race member and a protrusion part provided in the collar part. A curved ball passage having a semi-doughnut-shaped space having an outer arcuate surface forming an acute-angled end is provided in both of the flanges, and the other ends of the curved ball passage are connected to each other to form an annular ball circulation system. A miniature linear guide device having a ball return passage in the body, which is an axial hole with a circular cross section forming a passage. (2) The Miyuachi linear system according to claim 1, wherein the curved ball passage of the slider has a central curve curved into an arc when projected onto a plane perpendicular to the axial direction of the slider. Guide device.
