    摘要: A holder for supporting a rotary cutting blade such as a saw blade for an electric circular saw comprises a drive shaft rotatable on its own axis and having a larger-diameter portion and a smaller-diameter portion concentric therewith, a fixed flange fitted over the larger-diameter portion and having an annular support extending around and spaced radially from the smaller-diameter portion for mounting thereon the rotary cutting blade, and a removable flange having an annular projection inserted between the annular support and the smaller-diameter portion and secured by a screw axially to the smaller-diameter portion with the rotary cutting blade sandwiched between the fixed and removable flanges. The annular support and the smaller-diameter portion have distal ends lying axially flush with each other. The fixed flange and the larger-diameter portion are corotatably secured to each other by interengaging flat faces thereof, and likewise the removable flange and the smaller-diameter portion are corotatably fixed to each other by flat faces thereof held in interengagement.
