Zusammenfassung:	PROBLEM TO BE SOLVED: To reduce influence of a coolant in detecting coil temperature of a rotary electric machine.SOLUTION: Circumferentially extended portions 26 are provided at the tips of teeth 18 of the stator core 12 of a rotary electric machine. Coil conductors 22 are arranged to slots 20 between the teeth 18. In the slot 20, a temperature detector 28 and an elastic body 34 are arranged between the coil conductors 22 and the extended portions 26. The elastic body 34 energizes the temperature detector 28 toward the coil conductors 22 by own elastic force.SELECTED DRAWING: Figure 2 【課題】回転電機のコイル温度の検出において、冷却液の影響を小さくする。【解決手段】回転電機のステータコア１２のティース１８先端には、周方向に張り出した張出し部２６が設けられている。ティース１８間のスロット２０には、コイル導線２２が配置される。スロット２０内において、コイル導線２２と張出し部２６の間に温度検出体２８と弾性体３４が配置される。弾性体３４は、自身の弾性力によって温度検出体２８をコイル導線２２に向けて付勢している。【選択図】図２
