を得て、この力で内刃１２の刃板１２ａの刃端面を外刃
４の内面に密接させるようになっている。The inner blade 12 is biased upward by the spring force of the coil spring 14 provided by winding the shaft portion 11d. The spring 14 is elastically deformed by mounting the outer cutter body 2 on the main body case 1, thereby obtaining a biasing force that pushes up the inner cutter 12, and this force causes the blade end surface of the blade plate 12a of the inner cutter 12 to move to the outer cutter 4. It is designed to be closely attached to the inner surface of the.
従来の技術においては、コイルバネ１４の力で内刃１２
を押し上げることによって、この内刃１２と外刃４とを
密接させているため、第８図に示すような力関係とな
る。つまり、内刃１２を押し上げて外刃４に密接させる
コイルバネ１４の力をＡとした場合、外刃ケース３の段

であるが、使用時においては電気かみそりを顔に押し当
てる力Ｃによる反力Ｄが上記係止力Ｂとは逆方向、つま
り下向きに作用するから、使用時における実際の係止力
Ｂは（Ａ−Ｄ）／２となる。In the conventional technique, the inner blade 12 is driven by the force of the coil spring 14.
Since the inner blade 12 and the outer blade 4 are brought into close contact with each other by pushing up, the force relationship shown in FIG. 8 is obtained. That is, when the force of the coil spring 14 that pushes up the inner blade 12 to bring it into close contact with the outer blade 4 is A, the locking force B of the locking portion 4a of the outer blade 4 with respect to the stepped portion 3b of the outer blade case 3 is A / 2.
However, since the reaction force D due to the force C that presses the electric razor against the face at the time of use acts in the direction opposite to the locking force B, that is, downward, the actual locking force B at the time of use is ( A-D) / 2.
このため、顔と刃面との接触点における外刃４と内刃１
２との接触圧は、上記付勢力Ａに加えて上記押し当て力
Ｃの反力Ｄが加わって増加するが、それ以外の部分にお
いては、上記Ｂ＝（Ａ−Ｄ）／２の関係から明らかなよ
うに、上記反力Ｄが相殺力として作用して外刃４と内刃
１２との接触圧は低下する。Therefore, the outer blade 4 and the inner blade 1 at the contact point between the face and the blade surface
The contact pressure with 2 increases by adding the reaction force D of the pressing force C in addition to the urging force A, but in the other portions, from the relation of B = (A−D) / 2. As is apparent, the reaction force D acts as a canceling force, and the contact pressure between the outer blade 4 and the inner blade 12 decreases.
そして、ひげには長さがあって、顔と刃面との接触点以
外の部分においても、ひげをとらえて切断が行われる
が、以上のように接触点以外の部分での刃圧が低下して
いる従来の構成によれば、接触点以外の部分におけるひ
げの切断性能が良くないという問題があった。Then, the beard has a length, and cutting is performed by catching the beard even at a portion other than the contact point between the face and the blade surface, but the blade pressure at the portion other than the contact point is reduced as described above. However, according to the conventional configuration, there is a problem that the whisker cutting performance is not good at portions other than the contact points.
なお、この点を改善するのにコイルバネ１４の付勢力を
高めることによって、上記反力Ｄの作用に拘らず接触点
以外の部分での接触圧が保持されるようにすることが考

との接触点における刃圧が高くなり過ぎてしまうから、
モータ９に負荷が増大するとともに刃面の温度が上昇し
て、モータ９や外刃４の寿命が低下する。よって、実際
的な対策ではない。In order to improve this point, it is conceivable to increase the biasing force of the coil spring 14 so that the contact pressure is maintained at portions other than the contact point regardless of the action of the reaction force D. However, in such a case, the blade pressure at the contact point between the face and the outer surface becomes too high,
As the load on the motor 9 increases, the temperature of the blade surface rises, and the life of the motor 9 and the outer blade 4 decreases. Therefore, it is not a practical measure.
また、内刃１２は、コイルバネ１４によって軸部１１ｄ

４の内面と内刃１２との間に隙間ができ、それが原因し
てひげの切断性能が低下することがあるという問題があ
った。In addition, the inner blade 12 has a shaft portion 11d formed by a coil spring 14.
Is pushed up along the axial direction of and is brought into close contact with the inner surface of the outer blade 4, but when the outer blade 4 is pressed against the face, the reaction force D causes
Inner blade 12 together with outer blade 4 while compressing coil spring 14
Can be displaced in the direction of the support portion 11b along the shaft portion 11d.
Since the inner blade 12 is movable in the direction away from the inner surface of the outer blade 14 in this way, when the outer blade 4 is strongly pressed against a hard part such as a chin, the outer blade 4 locally corresponds to it. It may be transformed into. Then, as the deformed portion projects toward the inner surface side of the outer blade 4, the local projection portion pushes the inner blade 12, and the inner blade 12 is moved to the outer blade 4 according to the projection amount of the local projection portion. Displace away from the inner surface of. Therefore, there is a problem that a gap is formed between the inner surface of the outer blade 4 and the inner blade 12 except for the locally projecting portion, which may reduce the cutting performance of the whiskers.
したがって本発明の目的は、外刃やモータの寿命の低下
を損うことなくひげの切れ味を向上させることができる
とともに、外刃の内刃側への局部的変形をなくして切断
性能の低下を防止できる往復動電気かみそりを提供する
ことにある。Therefore, the object of the present invention is to improve the sharpness of the beard without impairing the reduction in the life of the outer blade and the motor, and to reduce the cutting performance by eliminating the local deformation of the outer blade toward the inner blade. It is to provide a reciprocating electric razor that can be prevented.

ように固定的に設けたものである。In order to solve the above problems, the present invention provides pressure-receiving portions on both side edges of the outer blade, and between the pressure-receiving portions and the outer blade case to which the outer blade is attached, the outer blade and the outer blade. An urging means for pressing the pressure receiving portions is provided on the main body case side to which the outer blade body having a case is attached, and an inner blade reciprocating in the width direction of the main body case by sliding on the inner surface of the outer blade, The inner blade is fixedly provided so as not to move in the axial direction of the shaft portion to which it is attached.

を防止できる。In the reciprocating electric shaver of the present invention, when the outer blade body is attached to the body case, the outer blade body is provided between the pressure receiving portions respectively provided on both side edges of the outer blade and the outer blade case provided in the outer blade body. The biasing means causes elastic deformation. As a result, the entire outer blade is pushed toward the main body case side to which the outer blade body is attached via the pressure receiving portions, so that the outer blade comes into close contact with the inner blade. Then, in use, a reaction force against the force of pressing the electric razor against the face is added to the contact point between the face and the blade surface, and the contact pressure between the outer blade and the inner blade at this contact point increases, The direction of the force and the direction of the urging force generated by the elastic deformation of the urging means are the same, and the force of pushing the pressure receiving portion is not reduced by the action of the reaction force. Therefore, the contact pressure between the outer blade and the inner blade is prevented from lowering in the portion other than the contact point, and the whisker cutting performance in the portion other than the contact point between the face and the blade surface can be improved. Also, the inner blade that slides on the inner surface of the outer blade is fixed so that it does not move in the axial direction of the shaft that supports it, so the outer blade is strongly pressed against a hard part such as the chin. In this case, the inner blade can prevent the pressing portion of the outer blade from being locally deformed correspondingly. Therefore, no gap is formed between the inner surface of the outer blade and the inner blade, and it is possible to prevent deterioration of the beard cutting performance.

とは勿論である。Also in the configuration of such another embodiment, the direction of the reaction force H of the force G that presses the electric razor acting on the contact point between the face and the blade surface against the face during use, and the coil spring 24 of the biasing means 22. The direction of the urging force E generated by the elastic deformation is the same. Therefore, since the pressing force F that brings the outer blade 4 into close contact with the inner blade 12 is not reduced by the action of the reaction force H, the whisker cutting performance at the portion other than the contact point between the face and the blade surface can be improved. . Furthermore, since the inner blade 12 is fixedly provided so as not to be moved away from the inner surface of the outer blade 4 even when the outer blade 4 is strongly pressed against a hard portion such as a chin, It is possible to prevent the cutting performance from being deteriorated by forming a gap between the blades 4 and 12. Further, since the degree of compression of the coil spring 24 can be changed by moving the spring retainer plate 30 by advancing and retracting the adjusting screw 28, the blade pressure can be adjusted to a desired blade pressure corresponding to the user's whiskers and the like. .
