According to the configuration of the present invention, the outer blade locking pawl that engages and disengages with one of the pawl engaging portions of the outer blade body is integrated with the main body case, and the other pawl engaging portion of the outer blade body engages and disengages. Since the outer cutter locking body itself is made of synthetic resin that can be elastically deformed, the number of parts can be reduced by omitting springs and the like that were conventionally required. With this reduction in the number of parts, not only is it possible to attach the outer cutter by assembling the outer cutter locking body to the main body case, but the outer cutter locking body can also be attached to the outer cutter mounting surface. Since it can be attached by fitting it into the groove provided in the outer blade body, the assembly work of the outer blade attachment structure can be easily performed. Furthermore, manufacturing costs can be reduced by reducing the number of parts and assembly man-hours. Furthermore, since the outer cutter locking body has a spring plate portion that is slightly inclined, the outer cutter locking body is pushed and elastically deformed, and at the same time, the spring portion is elastically deformed to return the outer cutter locking body. energize. Due to the auxiliary spring action of such a spring plate portion, deterioration of the elasticity of the outer cutter locking body can be prevented over a long period of time, and the outer cutter body can be mounted and held without wobbling.

1, and then the motor 28 operates and the transmission shaft 42 rotates eccentrically with respect to its rotation shaft 40. Along with this, the transmission shaft 42 and the vibration part 4
Vibrating section 46 is reciprocated in the left-right direction at high speed according to the amount of eccentricity through engagement with engagement groove 46a of No. 6.
The movement of the vibrating part 46 at this time is allowed by the bending deformation of both ends of the flexible deforming part 47. Therefore, since the inner cutter body 50 reciprocates in sliding contact with the blade surface of the outer cutter body 60, the hair introduced from the outer cutter plate 60a can be shaved.
