PROBLEM TO BE SOLVED: To provide a roller guide device with which individual and whole center distance adjustment of a plurality of guide rollers are easily and rapidly performed and the precision of the center distance adjustment is improved. SOLUTION: When rotating three driven gears 43 by rotating a ring-like drive gear 44 with an adjusting shaft 461 projected to the outside of a frame 2, a rotary shaft 42 which is connected to the driven gears 43 by a clutch means 47 is rotated. When rotating the rotary shaft 42, a gear 411 is rotated by moving a clutch 412 which is screwed on the rotary shaft 42 back and forth and oscillating positions of three roller holders 3 on which the gear 411 is mounted can be simultaneously changed by the same distance. On the other hand, when the engagement with the driven gear 43 is disengaged with the clutch means 47, the rotary shaft 42 is individually rotated with tools or the like. COPYRIGHT: (C)2006,JPO&NCIPI
