PURPOSE: To prevent wear of a contact surface, to improve supporting rigidity, to compactly constitute the whole of the device and to easily perform working and assembling, in a linear guide. CONSTITUTION: This linear guide 1 is constituted of a rail 10 having first and second rail surfaces 10a and 10b extending in a straight line and forming an angle &thgr; with each other and a slide unit 2 provided slidably on the rail 10. The slide unit 2 has a slide unit main body 20, first and second needle bearings 30 and 35 inserted into each through hole 25 and 26 formed in the slide unit main body 20 and first and second support shafts 22 and 24 which rotatably support each of the first and second needle bearings 30 and 35 and are disposed in a direction orthogonal to the extending direction of each rail surface 10a and 10b.
