PROBLEM TO BE SOLVED: To provide a film cutting unit in which the gap adjustment between a rotating blade and a stationary blade can be simply and properly performed even by anyone.SOLUTION: A rotating blade 10 and a stationary blade 20 have their respective blade tips 11a, 21a formed on a cylindrical surface cs centering around a rotary axis of the rotating blade 10 as a center axis, and have circular arc surfaces 11b, 21b on which their respective blade tips 21a, 11a of their counterparts can slide, and the blade tip 21a of the stationary blade 20 is formed while being tilted to the rotary axis of the rotating blade 10 to attain a shear angle. A position adjustment mechanism 30 includes a push pin 34 for pushing the stationary blade 20 on the rotating blade 10 side, and a coil spring 36 for urging the push pin 34 in the pushing direction, wherein the push pin 34 is abutted on the stationary blade 20 to push it, causing either blade tip of the stationary blade 20 or the rotating blade 10 to abut on the circular arc surface of the counterpart to perform the position adjustment of the stationary blade, using the urging force of the coil spring 36 to apply a shock to the fixed blade 20. |
