Abstract:
A linear motion guiding device that is unlikely to cause a damage to a tongue unit of an end cap even when the linear motion guiding device is used under high-speed conditions is provided. An end cap ( 22 ) includes, at an end of a side of a raceway of an arc groove ( 222 ) that forms an outer peripheral surface of a direction changing passage ( 42 ), a tongue unit ( 25 ) that scoops up a ball ( 3 ) from a raceway ( 41 ) and guide the ball to a direction changing passage ( 42 ). A distal end surface ( 251 ) of the tongue unit includes a plane ( 251 a ) perpendicular to a direction along the raceway ( 41 ) and a circular-arc surface ( 251 b ) that caves into an arc shape from the plane. A curvature radius of a circular-arc surface is smaller than a radius of the ball. A center of a circle indicating a curvature of a circular-arc surface is present on a line shifted from a groove bottom line of the arc groove by at least an offset amount between a raceway groove ( 12 ) of a side of the guide rail and the raceway groove ( 212 ) of a side of the slider.

Claim (Index 1):
A linear motion guiding device comprising:\n a guide rail; a slider; and a plurality of balls, wherein the slider is provided at an outside of the guide rail; the guide rail and the slider face with each other and respectively include, at mutually facing positions, a raceway groove f to form a raceway of the ball, and both of the raceway grooves extend in a longer direction of the guide rail; the slider includes a slider main body and a pair of end caps; the raceway groove and a return path of the ball are formed to the slider main body, and a direction changing passage of the ball is formed to the end cap; the ball is provided in a circulation pathway including the raceway, the return path, and the direction changing passage; an arc groove configured to form an outer peripheral surface of the direction changing passage is formed to a surface of a side of the slider main body of the end cap; a tongue unit configured to scoop up the ball from the raceway and guide the ball to the direction changing passage is formed to an end of a side of the raceway of the arc groove; a distal end surface of the tongue unit includes a plane perpendicular to a direction along the raceway and a circular-arc surface configured to cave into an arc shape from the plane; a curvature radius of the circular-arc surface is smaller than a radius of the ball; a center of a circle indicating a curvature of the circular-arc surface is present on a line shifted from a groove bottom line of the arc groove by at least an offset amount between the raceway groove of a side of the guide rail and the raceway groove of a side of the slider; and via the ball rolling within the raceway in a load state, the slider linearly moves along the guide rail.
