Claim:
1. A saw band guiding device comprising: a fixed insert holder; a fixed insert guide fixed to a tip end portion of the fixed insert holder, the fixed insert guide having a first saw band guiding surface for guiding one side surface of a saw band; a movable insert holder being rotatable relative to the fixed insert holder; a movable insert guide fixed to a tip end portion of the movable insert holder, the movable insert guide being opposed to the fixed insert guide and having a second saw band guiding surface for guiding another side surface of the saw band; a hinge pin fixed to the fixed insert holder and directed in parallel with the first saw band guiding surface; and an elongated hole opened on the movable insert holder and elongated in a direction perpendicular to the first saw band guiding surface, wherein the hinge pin fits in the elongated hole to pivotally support the movable insert holder while allowing the movable insert holder to move in the direction perpendicular to the first saw band guiding surface, whereby the movable insert holder is enabled to be regulated in directions where the movable insert holder gets closer to and away from the fixed insert holder while the first saw band guiding surface and the second saw band guiding surface are maintained parallel with each other.
