Claims

[Scope of utility model registration request]

A guide rail made of a long, thick, rigid body with ball rolling grooves extending in the axial direction on both sides, and a U-shaped guide rail to span over the guide rail, and a guide rail on both sleeves. A race member is provided with a ball rolling groove on its inner surface that faces the ball rolling groove of the guide rail, and a race member is provided on the outer surface of both sleeves of this race member and is provided inside with a ball rolling groove on one of the race members. First and second ball guide members forming communicating ball circulation passages, and rolling circulation between the ball rolling grooves of the race member and the guide rail and the ball circulation passages of the first and second ball guide members. The first and second ball guide members are configured by integrally combining a circulator having the ball circulation passage and a cap covering the circulator, and the ball guide member is provided with a large number of balls that can be freely inserted. The passage includes a ball return passage located on the outside of the circulator and parallel to the ball rolling grooves of the guide rail and race member, and a passage located at both axial ends of the circulator between the ball return passage and the guide rail and race member. A curved ball groove communicating with a ball rolling groove is formed, and a positioning hole is provided in one of the caps of the race member and the first and second ball guide members, and a positioning protrusion is provided in the other. A lightweight linear guide device, characterized in that the positioning protrusion is fitted into the positioning hole to fix the race member and the first and second ball guide members together to form a slider.
