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 3):
An end cap for a linear motion guiding device configuring a slider of the linear motion guiding device in which a guide rail, the slider, and a ball are provided, and via the ball rolling in a load state within a raceway formed with a raceway groove formed to a mutually facing position of the guide rail and the slider, the slider linearly moves along the guide rail, the end cap comprising:\n a first component in which a first leg unit provided at one side in a width direction of the guide rail is provided, an arc groove that forms an outer peripheral surface of a direction changing passage of a ball is formed, and, to an end of a side of the raceway of the arc groove, a tongue unit configured to scoop up the ball from the raceway and guide the ball to the direction changing passage is formed; a second component in which a second leg unit provided to the other side in the width direction of the guide rail is provided, an arc groove that forms an outer peripheral surface of a direction changing passage of the ball is formed, and, to an end of a side of the raceway of the arc groove, a tongue unit configured to scoop up the ball from the raceway and guide the ball to the direction changing passage is formed; and a third component including a part provided above the guide rail and an engagement surface with the first component and the second component; wherein, the first component and the second component are made of a metal material; and the first component and the second component, and the third component are connected via a fastener component.
