（産業上の利用分野）
この考案は直接膚に触れる振動刃体を備えた剃
刀に関するものである。[Detailed description of the invention] (Field of industrial application) This invention relates to a razor equipped with a vibrating blade that comes into direct contact with the skin.
（従来の技術）
従来、軽便剃刀は刃体を膚表面に当てて刃先に
対し直交する方向に移動させ、ひげ剃り動作を行
うものであつた。従つて、膚表面の凹凸を一方向
へ撫でるようなひげ剃り動作であるため、膚表面
のひげを１回のひげ剃り動作を以つてその根本か
ら剃り落とすことは困難であり、ひげの剃り残し
が多いばかりでなく、刃体がひげを押すように切
るいわゆる押し切りであるため、剃り味が悪くな
る難点があつた。(Prior Art) Conventionally, a handy razor has been used to perform a shaving operation by placing the blade against the skin surface and moving it in a direction perpendicular to the cutting edge. Therefore, since the shaving motion is like stroking the unevenness of the skin surface in one direction, it is difficult to shave off the beard on the skin surface from the root in one shaving motion, resulting in unshaved beard. Not only are there a lot of shavings, but the fact that the blade cuts by pressing against the beard makes for a poor shave.
この問題を解決するため、刃体に対し例えば
0.01〜0.5mmぐらいの振幅を有する振動を前後、
左右、上下方向若しくはそれらを組合せた方向に
与えることにより、剃刀としての性能をより一層
向上させることができるようにしたものが公知に
なつている。（例えば特開昭56−75190号公報参
照）
（考案が解決しようとする問題点）
このような振動刃体を備えた剃刀では、安全
上、刃体の刃先の延設方向に対し直交する前後方
向へ刃体が振動することが望ましいが、これだけ
では剃り味が十分でないので、これに他の方向の
微振動が加わることが理想である。 To solve this problem, for example,
Vibration with an amplitude of about 0.01~0.5mm back and forth,
There are known razors that can further improve the performance of the razor by applying it in the left and right, up and down directions, or a combination thereof. (For example, see Japanese Patent Application Laid-Open No. 56-75190.) (Problems to be solved by the invention) For safety reasons, in a razor equipped with such a vibrating blade, the front and back of the blade are perpendicular to the extending direction of the cutting edge of the blade. It is desirable for the blade to vibrate in this direction, but since this alone does not provide a sufficient shaving quality, it is ideal to add slight vibrations in other directions.
ところが、前述した公報のものでは、その従動
体の形状からして、このような前後方向振動を中
心とした複合振動を刃体に与えるには不十分であ
る。 However, in the above-mentioned publication, due to the shape of the driven body, it is insufficient to impart such compound vibration centered on longitudinal vibration to the blade body.
そこで、特に従動体の形状を改良することによ
り、この複合振動を与え易くして剃り味をより一
層向上させたものが本考案である。 Therefore, the present invention is designed to improve the shaving quality by making it easier to apply this complex vibration by particularly improving the shape of the driven body.
