（産業上の利用分野）
この発明は、毛髪の柔軟性を、頭部から毛髪を剪除する
ことなく直接測定可能とする方法及び装置に関する。Detailed Description of the Invention 3. Detailed Description of the Invention (Field of Industrial Application) The present invention relates to a method and apparatus that enable direct measurement of hair flexibility without shearing the hair from the head.
（従来の技術）
毛髪は、個人差、年令差、汚れ共合等によってその柔軟
性が異なっており、柔軟性を測定することによって、毛
髪の健康状態の診断に資することが出来る。(Prior Art) The flexibility of hair varies depending on individual differences, age differences, dirt contamination, etc., and measuring the flexibility can contribute to diagnosis of the health condition of hair.
しかしながら、従来はこのような毛髪の柔軟性を測定す
る有効な方法は提案されていなかった。However, no effective method for measuring hair flexibility has been proposed so far.

髪束を装入し、毛髪束の前後における流体の圧力変化に
より毛髪の柔軟性を測定するようにしたことを特徴とす
る。(Means for Solving the Problems) In order to solve the above problems, the invention of ftIJl introduces a hair bundle into the flowing working fluid perpendicularly to the flowing direction, and It is characterized in that the flexibility of the hair is measured by the change in fluid pressure before and after the bundle.
又、第２の発明が採った手段は、作動流体を流過させる
流路と、該流路内に毛髪束を直交して装入する装入孔と
、該装入孔の前後に配設された圧力センサーとからなる
ことを特徴とする。Further, the means taken by the second invention includes a flow path through which the working fluid flows, a charging hole through which the hair bundle is inserted perpendicularly into the flow path, and disposed before and after the charging hole. and a pressure sensor.
（作 用）
流体の流過方向と直交して毛髪束を装入し、毛髪を流過
方向に彎曲させるために流体が喪失したエネルギーを、
毛髪束の前後における流体の圧力変化により測定する。(Function) A hair bundle is inserted perpendicular to the direction in which the fluid flows, and the energy lost by the fluid to bend the hair in the direction in which the fluid flows is absorbed.
It is measured by the change in fluid pressure before and after the hair clump.
毛髪の柔軟性は、前記流体の喪失エネルギーと相関して
いるため、圧力変化を測定することによって毛髪の柔軟
性を知ることが出来る。Since the flexibility of the hair is correlated with the energy lost in the fluid, the flexibility of the hair can be determined by measuring the pressure change.
（発明の効果）
