ABSTRACT:
A screw shaft supporting structure capable of absorbing elongation of a screw shaft due to changes in environmental temperatures irrespective of the position of the rotary blade on said screw shaft is disclosed. In the sheet material cutting device, that portion of the screw shaft which is supported by a bushing and another portion thereof supported by a frame end absorbs elongation of the screw shaft due to heat. When the supporting member holding the rotary blade is positioned at A in FIG. 1, elongation of the screw shaft due to thermal expansion is absorbed in a gap formed between the stepped portion of the screw shaft and the frame end. When the supporting member holding the rotary blade is positioned at B in FIG. 1, elongation of the screw shaft due to thermal expansion is absorbed in a gap S1 formed between the stepped portion of the screw shaft and the bushing.
