Title (EN) EDDY-CURRENT TYPE INSTRUMENT
(FR) INSTRUMENT DE TYPE À COURANT DE FOUCAULT
(JA) 渦電流式計器
Abstract:
(EN) The present invention reduces the number of parts for fixing an end part of a spiral spring provided to an eddy-current type instrument. In this eddy-current type instrument (10), an instrument main body (12) is provided in a case (11) and a dial (13) with character information displayed thereon is placed on a support part (49) provided on a cover (40) of the instrument main body (12). A spiral spring (70) for impelling a second rotating shaft (51) is disposed above the cover (40). The support part (49) rises integrally from the cover (40) so as to extend further upward than the spiral spring (70) and is positioned in the vicinity of the spiral spring (70). A fixing part (45) for fixing an end part (72) of the spiral spring (70) is formed integrally with the cover (40).
(FR) La présente invention concerne la réduction du nombre de pièces permettant de fixer une partie d'extrémité d'un ressort en spirale situé sur un instrument de type à courant de Foucault. Ledit instrument de type à courant de Foucault (10) comprend un corps principal d'instrument (12) situé dans un boîtier (11) et un cadran (13) comprenant des informations de caractère affichées sur ce dernier est placé sur une partie support (49) située sur un couvercle (40) du corps principal d'instrument (12). Un ressort en spirale (70) destiné à solliciter un second arbre rotatif (51) est disposé au-dessus du couvercle (40). La partie support (49) s'élève d'un seul tenant à partir du couvercle (40) de façon à s'étendre davantage vers le haut que le ressort en spirale (70) et est positionnée à proximité du ressort en spirale (70). Une partie fixation (45) permettant de fixer une partie d'extrémité (72) du ressort en spirale (70) est formée d'un seul tenant avec le couvercle (40).
(JA) 渦電流式計器に備えられた渦巻きばねの端部を固定するための部品点数を減らすこと。 渦電流式計器(10)は、計器本体(12)が、ケース(11)に設けられ、計器本体(12)の蓋体(40)に設けられた支持部(49)に、文字情報の表示された文字板(13)が載せられてなる。第2の回転軸(51)を付勢する渦巻きばね(70)は、蓋体(40)の上方に配置され、支持部(49)は、蓋体(40)から一体的に立ち上げられて渦巻きばね(70)よりも上方まで延びると共に、渦巻きばね(70)の近傍に位置する。渦巻きばね(70)の端部(72)を固定する固定部(45)は、蓋体(40)と一体的に形成されている。
