磁気的結合させる如く所定間隔離して突合せ状態でフレ
ームに装設し、磁石の角速度に比例して発生する渦電流
作用を渦巻ばねの弾性と釣合せて主軸の回転数を指針軸
の角度回転に変換するようにした渦電流式計器において
、上記フレームの下部に軸受筒部を垂設し、該軸受筒部
に主軸を回転自在に支承する軸受孔を形成し、且つ軸受
孔の下部に、軸受孔より径大な座ぐり状の係止孔を形成
し、一方上記主軸の下部に、可撓作用を付与した係止段
部を膨出形成し、該係止孔の座面と係止段部の段周面と
の間に、スペーサリングを主軸に回り止め状態で介在し
、上記主軸が回転したときにスペーサリングと係止孔の
座面とで滑動する如く構成したことを特徴とする渦電流
式計器の主軸取付装置。A magnet fixed to the upper end of the main shaft and a rotor fixed to the pointer shaft are magnetically coupled, separated by a predetermined distance, and mounted on the frame in a butt state, and the eddy current action generated in proportion to the angular velocity of the magnet is absorbed by the elasticity of the spiral spring. In an eddy current type instrument that converts the rotational speed of the main shaft into angular rotation of the pointer shaft in balance with the above-mentioned frame, a bearing cylinder part is installed vertically at the bottom of the frame, and the main shaft is rotatably supported in the bearing cylinder part. A counterbore-shaped locking hole with a larger diameter than the bearing hole is formed in the lower part of the bearing hole, and a locking step portion with a flexible action is expanded at the lower part of the main shaft. A spacer ring is interposed between the seating surface of the locking hole and the stepped circumferential surface of the locking stepped portion in a state that prevents it from rotating around the main shaft, and when the main shaft rotates, the spacer ring and the locking hole are rotated. A main shaft mounting device for an eddy current type instrument, characterized in that it is configured to slide on the seat surface of the eddy current instrument.
