ABSTRACT:
A main body of an inner blade is inserted into an inner blade insertion hole of an inner blade frame such that the main body can extend and retreat, a tip end cutting edge is pushed by a spring such that it comes into contact with an inner peripheral surface of a slit outer blade, the main body of the inner blade projecting outward from the inner blade insertion hole is bent rearward in a rotational direction, and the cutting edge of the inner blade is located rearward of the main body in the inner blade insertion hole in the rotational direction. With this configuration, the cutting edge does not fall forward in the rotational direction, and no gap is generated between the cutting edge and the inner peripheral surface of the slit outer blade.
