である。Conventional comb-shaped blades are made of stainless steel,
As shown in Fig. 8, the fixed blade A and the t+J moving blade B are overlapped and are in contact with the cutting blade C and the sliding part E other than the cutting blade. However, there was a drawback that the friction coefficient of the 1D movement of the blade was large and the sliding load was large. Therefore, even if the sliding surfaces are lubricated with oil, the lubricating oil will be washed away when hair is shaved with soap or washed with water, and the effect will be 1/-1°.Therefore, the object of the present invention is to Is there an electric razor that can reduce the sliding load without using Jun I? It is to provide.

By engaging the other part of the swing drive punch 9 with a,
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 is a cutting blade 11a.
Grooves 19.20 are formed in the direction of the sliding force of the sliding parts other than the grooves 19.20, and the sliding grooves 19.20 are formed of a high hardness material 1 such as niobium-based F-T mix (Vickers hardness 1000 to 1500). Members 21 and 22 are embedded by adhesive or the like, and their surfaces are polished so as to be flush with the sliding surface of the cutting blade 11a. Also, facing the sliding members 21 and 22, as shown in Fig. 4, there is a circular arc groove 23 in one of the sliding parts other than the cutting edge of the fixed blade 10.
A pair of holes of 24ft are formed in the capacity of the sliding part,
An arc-shaped sliding member 25 of high hardness made of the same material as described above is buried in the arcuate groove 23 by adhesive, and a locking protrusion 27 is fitted onto the other band-shaped sliding member 26 made of the same material and fixed by adhesive. are doing. On the surfaces of these sliding members 25 and 26, hemispherical protrusions 28 of the same radius are continuously formed at regular intervals to form an uneven surface, and the tops of the protrusions 28 are pressed into the same plane. It is arranged so that it comes into contact with the surface of the mJ recording and moving member 2122.

The joint 7 rotates, the swing drive punch 9 swings, the movable blade 11 is pressed against the fixed blade 10 by the push-up spring 12, and the square post 1
Fixed blade 10 above while supported by 61C? Sliding back and forth. At this time, the sliding surfaces other than the cutting edges Oa and lla come into point contact with the plane of the sliding member 21, 22 and the top of the protrusion 28 of the sliding member 25, 26 (Fig. 6), and the frictional resistance is significantly reduced. This reduces the sliding load. Moreover, since it is made of a highly hard material, it has better wear resistance than ordinary knife steel.

摺動負荷の低減になる。An example of @2 of this invention is shown in Figure @7. That is, the uneven portions of one of the high-hardness sliding members 25', 26' are formed into wave-like unevenness (29), which reduces the sliding load as in the first embodiment.

なお、その池、凹凸部の形状は凸部の頂部が同一平面上
にあるという−ｋＶＰを満す限り任意である。Note that the shape of the pond and the concave and convex portions is arbitrary as long as it satisfies -kVP that the tops of the convex portions are on the same plane.

るという効果がある。As described above, the electric shaver of the present invention has a smooth surface on the comb-shaped movable blade or the fixed blade. For all π-hardness sliding members, a high-hardness sliding member is provided that has concave and convex portions in both directions, and the tops of the convex portions are on the same plane, so that parts other than the cutting blade are brought into sliding contact with this sliding member. Therefore, compared to the conventional method, the sliding resistance can be completely reduced without using a lubricant, and wear can also be reduced.
