PROBLEM TO BE SOLVED: To provide a double stator type rotary electric machine which prevents two stators from being axially or radially displaced from each other.SOLUTION: The double stator type rotary electric machine includes a holding member 27A including: a connecting part 272 for integrally connecting an outer stator 14 and an inner stator 17; and holding parts (271 and 273) for holding one of or both at least a part of an outer peripheral surface of the outside stator 14 and at least a part of an inner peripheral surface of the inner stator 17 in contact with the surfaces. Thus, the outer stator 14 and the inner stator 17 are integrally connected by the connection part 272 and the outer peripheral surface of the outer stator 14 or the inner peripheral surface of the inner stator 17 is held by the holding part (271, 273). Therefore, the outer stator 14 and the inner stator 17 can be prevented from being relatively axially or radially displaced.SELECTED DRAWING: Figure 2 【課題】二つのステータの相互間で軸方向や径方向のずれを防止するダブルステータ型回転電機を提供することである。【解決手段】ダブルステータ型回転電機において、外側ステータ１４と内側ステータ１７とを一体的に連結する連結部２７２と、外側ステータ１４の外周面の少なくとも一部および内側ステータ１７の内周面の少なくとも一部のうちで一方または双方に接して保持する保持部（２７１，２７３）とを備える保持部材２７Ａを有する。この構成によれば、連結部２７２によって外側ステータ１４と内側ステータ１７とを一体的に連結するとともに、保持部（２７１，２７３）が外側ステータ１４の外周面や内側ステータ１７の内周面を保持する。よって、外側ステータ１４と内側ステータ１７との間で相対的な軸方向や径方向のずれを防止することができる。【選択図】図２
