ABSTRACT:
A parallel guide apparatus comprises two roller-type linear guide apparatuses disposed in spaced-apart, confronting, parallel relation. Each roller-type linear guide apparatus comprises a rail 2 and a slider 3 slidably assembled into the rail 2 via a roller 9. The rail 2 is made by deforming a plate material to form a channel-shaped cross section. The slider 3 has at least three roller 9 which are disposed such that their entire width d becomes slightly larger than the distance 2 between opposite guide planes of the rail 2. The rollers 9 supported on the slider 3 are brought into contact with guide planes of the rail 2. The rollers 9 may be made of a sintered metal impregnated with a lubricant. The rollers 9 in one of the roller-type linear guide apparatus are slightly movable toward the rollers 9 in the other roller-type linear guide apparatus.
