Abstract
End caps made from synthetic resin are respectively joined to opposite ends of a slider main body of a linear guide apparatus. Each end cap having a substantially inverted U-shape has a joining end surface formed with curved passages to bring ball rolling grooves of the slider main body into communication with each other to form circulating passages. A feed oil groove is also formed in the joining end surface of the end cap to supply lubricating oil to the curved passages. In order to prevent leakage of the lubricating oil from a minute gap between the joining end surfaces of the end cap and the slider main body, a band-shaped protrusion having two parallel ridges is formed along a peripheral edge of the joining end surface of the end cap. The band-shaped protrusion is elastically deformed by a clamping force when the end cap is joined to the slider main body by fixing screws such that the minute gap between the end cap and the slider main body is filled with the deformed band-shaped protrusion.
