Abstract:
A linear guide apparatus maintaining a high dust-proof performance over an extended period of time and includes side seal units attached to end parts of a slider in the axial direction. Each side seal unit is provided with: a first seal member, at the slider, arranged in the axial direction of the slider; a second seal member at the outside of the slider in the axial direction; and a lubricating member held between the first and second seal members. The first seal member has first lip parts sliding against the rolling element rolling grooves of the guide rail, while the second seal member has second lip parts sliding against the rolling element rolling grooves. The lubricating member has a first oil-containing member for supplying lubricant to the rolling element rolling grooves. The first and second lip parts are arranged not to come into contact with the first oil-containing member.
