A linear guide apparatus which can be applied to both straight rail and curved rail comprising a pair of upper and lower rolling grooves and for rolling members are formed in each side surfaces of a guide rail. A pair of upper and lower grooves for loaded rolling members, which respectively correspond to the rolling grooves, are formed in each inner surfaces of a slider which straddle the guide rail. One of the rolling grooves is a straight rolling groove which is formed to be parallel with the corresponding straight groove formed in the opposite inner surface of the slider. The other of the rolling grooves is a curved rolling groove in circular arc shape which has the same curvature as the corresponding curved rolling groove formed in the opposite inner surface of the slider.
