Summary:To provide a collector structure capable of constantly maintaining good electrical connection/insulation state between a collector ring and a conductor penetrating through the collector ring.SOLUTION: The collector structure having a collector ring disposed on a rotor part of rotary electric machine, comprises: a collector ring 3; a conductor 5 with outer peripheral insulation layer, which has the axial direction parallel to the rotation axial direction of a rotor with one end connected to the collector ring 3; and a collector ring 4' having a holding mechanism 11 using an elastic member in a through-hole through which the conductor 5 penetrates for holding the conductor 5 at a fixed position against centrifugal force accompanying rotation.SELECTED DRAWING: Figure 2 【課題】コレクタリングとコレクタリングを貫通する導体との電気的な接続／絶縁状態を常に良好に保つこと。【解決手段】回転電機の回転子部に配置されるコレクタリングを含むコレクタ構造であって、コレクタリング３と、回転子の回転軸方向と平行な軸方向を有し、コレクタリング３に一端を接続した、外周面を絶縁層化した導体５と、導体５が貫通する貫通孔部に、回転に伴う遠心力に対抗して導体５を定位置に保持する、弾性部材を用いた保持機構１１を設けたコレクタリング４′とを備える。【選択図】 図２
