End caps are respectively joined to opposite ends of a slider main body of a linear guide apparatus. Each end cap has curved passage for bringing the load rolling-element rolling groove of the slider main body into communication with the rolling-element return passage to thereby construct a rolling-element circulating passage for circulating a plurality of rolling elements. At least a portion of the end caps in contact with at least one of the rolling elements and guide rail is made of an oil containing material.
