Summary:A saw blade driving method and a band saw machine (1) in which an endless saw blade (23) is wound around a driving wheel (17) and a driven wheel (21) rotatably supported by a saw blade housing , the saw blade is rotationally moved by rotationally driving the driving wheel by the saw blade driving unit (253) and a cut material (W) is cut with the rotationally traveling saw blade, the method comprising the steps of: coupling the saw blade driving unit to the shaft (225) of the driving wheel in the floating state in the saw blade rotating direction with respect to the saw blade housing; controlling the saw blade rotating direction of the saw blade driving unit via a buffer part (297) provided at the saw blade housing; and damping a reaction force caused by the driving of the saw blade by the buffer part.
