Summary:PROBLEM TO BE SOLVED: To provide a rotating electric machine for vehicle capable of surely preventing infiltration of foreign matters into a space surrounding a brush or a slip ring, or into the periphery of a bearing through an exhaust opening. SOLUTION: A cylindrical body is constituted of a brush holder 53 and a slip ring cover 54. A sealing member 56 with an attraction opening 150 is located at one end of the cylindrical body, and a sealing member 55 is located at the other end of the cylindrical body to form a sealing mechanism. A groove section 43, which is led to an inner space in a bearing housing 44, is formed in the end surface of a frame 4 facing the sealing member 55. An axial opening 43a in the groove section 43 is blocked by a cover 55a which has an outer edge of the sealing member 55 extended.
