Abstract
【解決手段】集電環10は円筒形である。ブラシ保持リング14の内面には,3個のブラシ保持バネ16がネジ18で固定されていて,その先端にブラシ12が固定されている。ブラシ12は,ブラシ保持バネ16の弾性復元力によって,集電環10の外周面に押し付けられている。集電環10が回転すると,ブラシ12は集電環10の外周面に対して滑り接触する。ブラシ12は,銅が70重量%,黒鉛が30重量%の金属黒鉛質でできている。集電環10は,その全体がガラス状炭素でできている。集電環10をガラス状炭素にしたことにより,この集電環に接触するブラシの摩耗量が減少し,発塵の少ない長寿命の回転集電装置となった。
