Abstract

PURPOSE:To reduce distortion and to prevent bending of circular saw by holding the circular saw with projections on the inner diameter edge of a spacer thereby distributing centrifugal extending stress entirely over the circular saw. CONSTITUTION:Predetermined number of circular saws 13 end tubular spacers 12 are fitted alternately in parallel to the drive shaft 11 of a circular saw machine, and tightened by means of a nut 15 screwed to a threaded portion 14 at the tip of the drive shaft 11. Projections 16 for holding the circular saw 13 are arranged on the inner circumferential edge on the side face of the spacer 12, and a small gap is provided at portions except the projections 16 in order to prevent contact with the plate face of the circular saw 13. Since the circular saw 13 is held at inner diameter portion contactable with the drive shaft 11 through the spacer 12, centrifugal extending stress to be produced when the saw is operated is distributed entirely over the circular saw 13 thus preventing vibration of the circular saw 13.
