PROBLEM TO BE SOLVED: To solve problems of contacting means of skin and electrodes being easily slipped off, and storage capability and a sense of incongruity of appearance.SOLUTION: A hinged support 1 has a structure capable of rotating an arm plate 3 and an electrode end 2 centering on the hinged support 1, and realizes to bring the electrode end 2 into contact with the skin by appropriate pressure by making an elastic body act in the rotating direction. Also, an ear side hinged support 7, an ear side arm plate 8 and an ear side electrode end 9 are included in an ear. The ear side hinged support 7 capable of triggering elastic force in the rotating direction has the structure for bringing the ear side electrode end 9 into contact with the skin by the appropriate pressure through the ear side arm plate 8. An arm plate 3 is provided with a permanent magnet 4, and is attracted to the facing permanent magnet 5 by magnetic force when rotating centering on the hinged support 1. Thereby, it has a structure in which the electrode end 2 and the arm plate 3 can be stored, and also it has the structure in which the setting position of the hinged support 1 and the ear side hinged support 7 can be changed, respectively.SELECTED DRAWING: Figure 1COPYRIGHT: (C)2018,JPO&INPIT【課題】皮膚と電極のずれやすい接触手段の問題点と収納性や見た目の違和感を解消する。【解決手段】回転支点１はアームプレート３と電極端２を回転支点１を中心として回転できる構造であり、弾性体を回転方向に働かせることで、電極端２を皮膚に適切な圧力で接触させることを実現している。また耳にも耳側回転支点７と耳側アームプレート８、及び、耳側電極端９を備える。弾性力を回転方向に作用させうる耳側回転支点７が耳側アームプレート８を介して耳側電極端９を皮膚に適切な圧力で接する構造であり、アームプレート３は永久磁石４がそなえられ、回転支点１を中心に回転すると相対する永久磁石５に磁力で吸着することで、電極端２とアームプレート３が収納できる構造とし、各々、回転支点１及び耳側回転支点７の設定位置は変更しうる構造も取ることができる構造である。【選択図】図１
