  • the gap Sn increases between the blade body tip 45 of the movable blade 40 and the fixed sliding contact surface 34 a of the fixed blade 30, so that the skin S can be prevented from being caught.
  • FIG. 15 shows still another form of the inner surface 46 of the blade tip 45 of the movable blade 40.
  • the inner surface 462 has a curved shape having a raised portion at the center of the surface. In the case of this configuration, there is an effect of pushing back the skin S. Even with such a configuration, the effect according to the above (1) can be obtained.
  • FIG. 16 shows still another form of the inner surface 46 of the blade tip 45 of the movable blade 40.
  • the inner surface 463 is configured by two surfaces (a first surface 463a and a second surface 463b).
  • the inner surface 463 includes a first surface 463a that is substantially perpendicular to the fixed sliding contact surface 34a of the fixed blade 30, and a second surface 463b that is an inclined surface extending from the first surface 463a to the tip side. Even with such a configuration, the effect according to the above (1) can be obtained.
  • tip part 45 of the movable blade 40 is this. It is not limited.
  • FIG. 17 shows another form of the blade tip 45 of the movable blade 40.
  • a boundary portion 470 having a curved surface is provided between the inner surface 46 and the outer surface 47.
  • damage (abrasion) of the skin S caused by the movable blade 40 can be suppressed.
  • the boundary line 47a between the inner surface 46 and the outer surface 47 does not exist, and therefore the most advanced point 42a of the blade body 42 is used instead of the tip point 47b on the boundary line 47a (see FIG. 8). Using these, the distances L1 and L2 are defined.
  • a part of the cutting blade portion 48 provided at the blade tip portion 45 has a curved blade edge 48a.
  • 48a is not limited to this shape.
  • FIG. 18 shows another form of the cutting edge 48a provided at the blade tip 45 of the cutting edge 48.
  • the blade edge 480a has a chamfered portion. Even with such a configuration, damage to the skin S can be suppressed.
  • the distance between the most advanced point 32a of the blade body 32 of the fixed blade 30 and the most advanced point 42a of the blade body 42 of the movable blade 40 is set to be substantially “0”.
  • this step is not limited to approximately “0”.
  • the size of the step is allowed in the range of about 0 to 0.5 mm.
