本考案は上記構或となっているが、従来の振動子５の支
持脚１７．１８は本案の様に多数の支持脚片１６，１６
・・・・・・によって構威されているのではなく、枚の
板状支持脚となっている。The present invention has the above structure, but the support legs 17 and 18 of the conventional vibrator 5 are replaced by a large number of support leg pieces 16, 16 as in the present invention.
It is not supported by ......, but is made up of plate-like supporting legs.

ところで、本案の場合でも従来の場合でもモーター２が
回転すると、偏心カム３の回転によって、振動子５は両
端の支持脚１７．１７下端の取付足部？，６を支点とし
て左右に往復振動し、結合軸１１に装着されている内刃
体２２を駆動して外刃２４との協働作業によりひげを切
る。By the way, in both the present case and the conventional case, when the motor 2 rotates, the rotation of the eccentric cam 3 causes the vibrator 5 to move between the supporting legs 17 at both ends and the mounting foot at the lower end of 17. , 6 as fulcrums to drive the inner cutter body 22 attached to the coupling shaft 11 and cut the beard by working in collaboration with the outer cutter 24.

この時、駆動騒音をより少なくする為に、偏心カム３と
嵌合部１３の係合凹所１２との間隙はなるべく小さくす
るのが好適である。At this time, in order to further reduce drive noise, it is preferable to make the gap between the eccentric cam 3 and the engagement recess 12 of the fitting portion 13 as small as possible.

従って、その様に偏心カム３の径、及び係合凹所１２の
内径を定めて、偏心カム３を加工、及び振動子５を或型
するも、一般的には加工上の工程差及び或型加工の寸法
精度等に制限が有り、出来上がったものは少しきつく嵌
まり合った状態のものが出現する。Therefore, although the diameter of the eccentric cam 3 and the inner diameter of the engagement recess 12 are determined in this manner, and the eccentric cam 3 is processed and the vibrator 5 is made into a certain type, generally there are differences in processing steps and There are limits to the dimensional accuracy of mold processing, and some of the finished products fit a little too tightly.

この様に嵌今度合がきつくなるとモーター２に対する負
荷の増大となり、モーター２の回転数が落ちるようにな
り、結果として振動子５の振動数低下につながる。When the fitting becomes tight in this way, the load on the motor 2 increases, the rotational speed of the motor 2 decreases, and as a result, the frequency of the vibrator 5 decreases.

振動数が落ちると言う事は、切れ味の低下となり好まし
くない。A drop in vibration frequency is undesirable as it reduces sharpness.

又、切れ味は外刃２４と内刃々片２３との密着が強い程
、良いものであるが、これの達威の為にコイルスプリン
グ１９を強くすると、両刃２４．２３の密着度合が強ま
る代わりに、内刃体２２が動く時に、抵抗となり全体の
負荷が増大する。Also, the sharpness is better as the contact between the outer blade 24 and the inner blade pieces 23 is stronger, but if the coil spring 19 is strengthened to achieve this effect, the degree of contact between the double blades 24 and 23 will be strengthened. Furthermore, when the inner blade body 22 moves, it creates resistance and increases the overall load.

その結果、モーター２に対する負荷増大はモーター電流
値を上げ、モーターに悪影響を与えると共に・、振動子
５の低下にもつながり、前述の場合と同様切れ具合に問
題を生じる。As a result, an increase in the load on the motor 2 increases the motor current value, which has an adverse effect on the motor and also leads to a decrease in the vibrator 5, causing a problem in cutting quality as in the case described above.

従来は上述したように、振動音が小さく、振動数が切れ
味に最つども適した値となるように前記偏心カム３と振
動子５の嵌合部１３との嵌合を製作上、色々と調整して
いたもので、その作業は非常に労力が入り大変であった
。Conventionally, as mentioned above, various methods have been used to manufacture the fitting between the eccentric cam 3 and the fitting part 13 of the vibrator 5 so that the vibration noise is small and the vibration frequency is the most suitable value for sharpness. I had to make adjustments, and the work was very labor-intensive and difficult.

然し、本考案では、例え偏心カム３と嵌合部１３との嵌
合具合が少し強くなったとしても、支持脚片１６，１６
・・・・・・の何個かを第３図の影絵線で示したように
切取ることによって、可撓支持脚１７，１７全体の撓み
具合を調整することができる。However, in the present invention, even if the fit between the eccentric cam 3 and the fitting portion 13 becomes a little stronger, the supporting leg pieces 16, 16
By cutting out some of them as shown by the silhouette lines in FIG. 3, the degree of deflection of the entire flexible support legs 17, 17 can be adjusted.

即ち、切取ると余計撓み易くなり、嵌合がきつくなる事
の負荷増大から全体の負荷を少なくする事が可能となり
、振動子５の振動数が低下するのを防がれる。That is, when cut off, it becomes easier to bend, and since the load increases due to tighter fitting, it is possible to reduce the overall load, and the frequency of the vibrator 5 is prevented from decreasing.

よって適正な振動状態が得られ、良好な剃り味を維持で
きる。Therefore, an appropriate vibration state can be obtained, and a good shave quality can be maintained.

又、刃圧が強い場合にも、同様に前記支持脚片１６，１
６・・・・・・の切除により、正常になるよう対処でき
、非常に駆動調整が容易となる。Also, even when the blade pressure is strong, the supporting leg pieces 16, 1
By removing 6..., it is possible to normalize the condition, and drive adjustment becomes extremely easy.

この様に、従来は振動音が小さく、且切れ味が最つとも
鋭く発揮できるような振動状態にするのに、偏心カムと
目状振動子との嵌合部分のみでの嵌金具合を色々と加工
上から対策を行なって調整していたのを、本考案では、
合戊樹脂より或る■状振動子の可撓支持脚を多数の切込
を施すことによって分割された複数の支持脚片によって
構威し、この支持脚片のうち、適当数を切り除いて、支
持脚自体の可撓度を調整できるようにし、振動子の振動
状態を変えられる様或している。In this way, in the past, in order to achieve a vibration state that produces the lowest vibration noise and the sharpest cutting ability, various fitting conditions were used only at the fitting part between the eccentric cam and the eye-shaped vibrator. Previously, adjustments were made by taking countermeasures during processing, but with this invention,
A flexible support leg of a ■-shaped vibrator made of synthetic resin is constructed by a plurality of support leg pieces divided by making a large number of cuts, and an appropriate number of the support leg pieces are cut out. The flexibility of the supporting legs themselves can be adjusted to change the vibration state of the vibrator.

よって、偏心カムと振動子との嵌合部分は加工上精度の
高いものは要求されず、支持脚側の構造調整によって簡
単に最良なる状態を実現でき、従来より非常に簡単に、
騒音の発生を防ぎ且切れ味の増大を果たせる振動式電気
かみそりが提供できる。Therefore, the fitting part between the eccentric cam and the vibrator does not require high precision in machining, and the best condition can be easily achieved by adjusting the structure on the support leg side, which is much easier than before.
It is possible to provide a vibrating electric shaver that can prevent noise generation and increase sharpness.
