To include a correction unit for correcting unbalance of a rotor while securing strength of a holding member for holding the rotor.SOLUTION: A rotor of a rotary electric machine includes: a cylindrical rotor core; and a holding member having a cylindrical part on which the rotor core is attached on an outer peripheral side and an annular wall part extending inward in a radial direction from the cylindrical part. A clutch includes: a first frictional engagement plate fitted to an outer peripheral part of a clutch hub connected to a rotation element; a second frictional engagement plate fitted to an inner peripheral part of the cylindrical part of the holding member; and a piston capable of pressing the first frictional engagement plate and the second frictional engagement plate. The holding member has a cylindrical projection part extending from the annular wall to a piston side in an axial direction so as to define an engagement oil chamber together with the piston part, and a recess for correcting unbalance of the rotor, where the recess part overlaps with the projection part in the radial direction of the holding member when viewed from the axial direction.SELECTED DRAWING: Figure 3

    【課題】ロータのアンバランスを修正するための修正部をロータを保持する保持部材の強度を確保しつつ設ける。【解決手段】回転電機のロータは、筒状のロータコアと、ロータコアが外周側に取り付けられる筒状部および筒状部から径方向内側に延出される環状壁部を有する保持部材とを有する。クラッチは、回転要素に連結されるクラッチハブの外周部に嵌合される第1摩擦係合プレートと、保持部材の筒状部の内周部に嵌合される第2摩擦係合プレートと、第1摩擦係合プレートおよび第2摩擦係合プレートを押圧可能なピストンとを有する。保持部材は、環状壁部からピストンと共に係合油室を画成するように軸方向におけるピストン側に延出される筒状の突出部と、ロータのアンバランスの修正用の凹部とを有し、凹部は、軸方向からみて突出部と保持部材の径方向に重なっている。【選択図】図3
