PROBLEM TO BE SOLVED: To obtain a linear guide mechanism and an optical disk device which reduces resistance occurring with the movement of a movabIe part and which thereby enables its stable high-speed movement. SOLUTION: This is a linear guide mechanism that supports a movable part 27 movably in one direction against a fixed part 33, the movable part 27 being loaded with a light converging means 25 by which at least light from a light source is converged on the signal recording face of an optical disk D. The structure is such that the movable part 27 is provided on both sides with two inclined faces 31, 32 having a prescribed inclined angle, while the fixed part 33 is provided with two inclined faces 34, 35 corresponding to those 31, 32 of the movable part 27; that deformable belt-like supporting members 36, 37 are fixedly stored in a space formed by the pair of oppositely facing inclined faces of the movable part 27 and the fixed part 33; and that, by displacing each belt-like supporting members 36, 37 in the space, the movable part 27 is supported movably against the fixed part 33.
