Abstract
A saw blade tension adjusting apparatus of a band saw machine includes a retaining base, a movable base movably connected with the retaining base through two opposite sliding shafts, and a control unit having a handle and a cam connected with the handle so as to be driven to rotate between a tightening position and a loosening position. When the cam is located at the tightening position, the movable base is lifted by a large diameter portion of the cam to tighten the tension of a saw blade, and when the cam is located at the loosening position, the movable base is moved downwards to lean on a small diameter portion of the cam for loosening the tension of the saw blade.
