。 A flange part is bent to project outward in the radial direction from one end opening of the yoke formed in a cylindrical shape, and a male seal coupling part is coupled to the opening of the yoke. In a seal structure for a rotating electrical machine in which a sealing member is narrowly provided between a mating surface with a flange portion integrally molded so as to project outward, a sealing member receiving groove is provided on the mating surface of the flange portion on the end bracket side. , the sealing member is recessed in a ring shape having a width extending from the base end of the outer circumferential surface of the male seal coupling part to the outer curved part of the yoke side flange, and the sealing member is formed in substantially the same shape as the housing groove. and a ring-shaped protrusion integrally protruding from the outer edge of at least one end surface of the main body, with a blank space formed on the inner circumferential side of the protrusion. A seal structure for a rotating electrical machine, wherein the seal member has a main body portion accommodated in the accommodation groove, and a protrusion portion that is compressed and deformed by a flat surface portion of the yoke side flange portion.
