（産業上の利用分野）
この発明は、レール上に載宣されたライダを転動体を介
して移動自在としたストローク量の比較的短い個所に適
用するのに好適な直動ころがり軸受に関する。[Detailed Description of the Invention] (Industrial Application Field) This invention is suitable for application to a relatively short stroke area where a rider mounted on a rail is movable via rolling elements. Regarding linear motion rolling bearings.
（従来の技術）
直動ころがり軸受組立体はライダの長さに対し、レール
の長さが長く、ライダの長さに対し数倍に達し、レール
が外部に露出しているのが圧倒的に多い。(Prior technology) In linear motion rolling bearing assemblies, the length of the rail is longer than the length of the rider, reaching several times the length of the rider, and the rail is overwhelmingly exposed to the outside. many.

The length of the rail (1) is shorter than the length (L) of the rider (2) in the moving direction, especially (rider length = stroke length - length of the rail). Rail (1
) and the rider (2), the balls (3) are loaded in two rows of balls on each side of the rail (1). Each gauge is a track (9a) formed on the inner wall of the rider (2).

Further, a seal (6) is fixed to the return cap (5) together with the retainer (4), and the seal prevents dust from entering into the raceway.
