２２の表面に接触するようにしている。 A first embodiment of the invention is shown in FIGS. 1 to 6. That is, this electric shaver has a main body 1 which also serves as a grip, a built-in motor 2 and a battery 3, a drive rod 4 and a joint 5 attached to the motor shaft 2a, a holder 6 connected to the main body 1, and
An eccentric joint 7 built into the holder 6 is coupled to the joint 5. An eccentric shaft 8 with a roller is connected to the eccentric joint 7 and engages with one end of a swing drive rod 9. A blade portion 13 consisting of a comb-shaped fixed blade 10, a movable blade 11, and a push-up spring 12 is provided on the blade head 6a of the holder 6, and the engagement groove 14a of the drive element 14 provided on the movable blade 11 is connected to the drive rod 9. is engaged with the other end.
The fixed blade 10, the movable blade 11 and the push-up spring 12
As shown in FIG. 5, the square hole (not shown) of the push-up spring 12 is passed through a pair of square bosses 16 protruding from the blade base 15, and the guide elongated hole 17 of the movable blade 11 is passed through the square boss 16. furthermore, the fixed blade 10 is attached to the square boss 1
6 and attached by a fixing pin (not shown), a driver 14 provided on the movable blade 11 protrudes from a loose fitting hole 18 formed in the center of the fixed blade 10. As a result, the push-up spring 12 is supported by the blade base 15 and presses the movable blade 11 against the fixed blade 10, and the other end of the swing drive rod 9 engages with the engagement groove 14a of the driver 14. , the movable blade 11 slides back and forth on the fixed blade 10 to perform a cutting operation. As shown in FIG. 3, the movable blade 11 has grooves 19 and 20 formed in the sliding direction of the sliding portion other than the cutting blade 11a, and these grooves 19 and 20 are filled with niobium ceramic (Vickers hardness 1000 to 1500) or the like. Sliding members 21 and 22 formed of a high hardness material are buried by adhesive or the like,
Its surface is polished so as to be flush with the sliding surface of the cutting blade 11a. Further, facing the sliding members 21 and 22, as shown in FIG. 4, an arcuate groove 23 is formed in one of the sliding parts of the fixed blade 10 other than the cutting edge, and a pair of holes 24 are formed in the other sliding part. A highly hard sliding member 25 having an arc shape and made of the same material as above is buried in the arc groove 23 by adhesive, and a strip-shaped sliding member 2 made of the same material is embedded in the other part.
A locking protrusion 27 is fitted onto the hole 6 and fixed by adhesion. On the surfaces of these sliding members 25 and 26, hemispherical protrusions 2 with the same radius are continuously formed at regular intervals.
8 to form an uneven surface, and the top surfaces of the protrusions 28 are in the same plane with each other, and the sliding members 21,
22 surface.

The eccentric joint 7 rotates, the swing drive rod 9 swings, and the movable blade 11 is pushed up by the spring 12 to move the fixed blade 1
0 and slides back and forth on the fixed blade 10 while being supported by the square boss 16. At this time, the cutting edge 10
The sliding surfaces other than a and 11a are in point contact with the planes of the sliding members 21 and 22 and the tops of the protrusions 28 of the sliding members 25 and 26 (Fig. 6), and the frictional resistance is significantly reduced and the sliding load is reduced. Reduced. Moreover, since it is made of a highly hard material, it has better wear resistance than ordinary knife steel.
なお、凹凸部のある摺動部材２５，２６を可動
刃１１に設けてもよい。 Note that the movable blade 11 may be provided with sliding members 25 and 26 having uneven portions.
