Rotor for electric rotating machine and method for manufacturing the same

A rotor for an electric rotating machine, comprising:

• a core body member formed by stacking a plurality of core plates in an axial direction along a rotational axis, and including a plurality of through holes;
• first and second end plates annually formed and provided at respective side faces of the core body member, and including a plurality of through holes;
• and
• a fixing member inserted into each of the plurality of through holes provided at the core body member and the first and second end plates, and engaged with each of the first and second end plates at opposite ends of the fixing member;
• a plurality of positioning portions provided at an outer circumferential surface or inner circumferential surface of each of the first and second end plates, wherein when the fixing member is engaged with the first and second end plates, the positioning portions are engaged with positioning receive portions corresponding to the positioning portion and positioning at radially outer portion or radially inner portion of the first and second end plates;
• wherein
• when one of the first and second end plates is placed facing the side face of the core body member in a reversed state, the first and second end plates and the core body member are not assembled each other for at least one of the following reasons:
• a portion, at which the positioning portion is not provided, allocated at the outer circumferential surface or the inner circumferential surface of the first and second end plates contacts one of the positioning receive portions;
• the positioning portion which is not engageable with the positioning receive portion contacts to the positioning receive portion;
• and
• a relative position between the through hole of the core body member and the through hole of the first and second end plates is shifted in a circumferential direction;
• and wherein
• in a state where one of the first and second end plates is placed facing the side face of the core body member in a correct state, one of the positioning portions of the first end plate and one of the positioning portions of the second end plate are located at opposite sides relative to the rotational axis.
