Zusammenfassung:To provide a cutting device which can easily and surely cut a material to be cut.SOLUTION: A cutting device 1 includes: a support body 10; a rotor 20 which is rotatably supported around a support shaft by the support body 10; rotary blades 30, 40, 50 which are provided in the rotor 20; and a stationary blade 60 which is mounted in the support body 10 so that ridge lines of the rotary blades 30, 40, 50 and a ridge line of a blade face each other. The cutting device cuts a material to be cut between the rotary blades 30, 40, 50 and the stationary blade 60 by rotation of the rotor 20. The ridge line 61 of the blade of the stationary blade 60 extends along an axial direction of the support shaft. The ridge lines of the blades of the rotary blades 30, 40, 50 are formed into a V-shape in a plan view so that a center section along the axial direction of the support shaft projects in a rotation direction and are formed into a circular arc shape around the support shaft in a side view. Therefore, a gap between the ridge lines of the rotary blades 30, 40, 50 and the ridge line of the blade of the stationary blade 60 is maintained constant during rotation of the rotor 20.SELECTED DRAWING: Figure 1 【課題】 被切断物の切断を容易且つ確実に行うことができる切断装置を提供する。【解決手段】 支持体10と、支持体10に支軸周りに回転自在に支持された回転体20と、回転体20に設けられた回転刃30,40,50と、回転刃30,40,50と刃の稜線同士が対向するように支持体10に取り付けられた固定刃60とを備え、回転体20の回転により回転刃30,40,50と固定刃60との間で被切断物を切断する切断装置1であって、固定刃60の刃の稜線61は、支軸の軸方向に沿って延びており、回転刃30,40,50の刃の稜線は、支軸の軸方向に沿った中央部が回転方向に突出するように平面視でV字状に形成されており、側面視において支軸を中心とする円弧状に形成されることで、回転体20の回転中に回転刃30,40,50および固定刃60の刃の稜線同士の隙間が一定に維持される。【選択図】 図1
