PURPOSE: To provide a blade holder of a multiple balde type cutter whose plural blades can be accurately tensioned at equal intervals and by which the enlargement by an increase in the blade number can be suitably performed not as a mere scale up and whose structure is simple and which can be easily handled. CONSTITUTION: A blade holder is provided with a beam part 14 to engage with end parts of plural blades 20 which are layered with spacers 22 and are juxtaposed at prescribed parallel intervals, and is provided with protrusively tensioning arms 16 extendedly arranged up to the vicinity of an intermediate part of a blade length in the tensioning direction of the blades 20 in respective both end parts of the beam part 14, and is provided with a pair of oppositely arranged holding frames 12, guide parts 24 which are arranged between the opposing protrusively tensioning arms 16 of a pair of holding frames 12 and guide both holding frames 12 so as to be capable of contacting-separating and plates 30 sandwiched between the opposing protrusively tensioning arms 16 so as to maintain its tensile force when a pair of holding frames 12 are separated from each other so as to apply tensile force to the plural blades 20. |
