Vehicle rotating electrical machine

A vehicle rotating electrical machine, comprising:

• a rotor rotated with a rotary shaft as a center;
• a stator disposed opposing so as to enclose an outer periphery of the rotor;
• a cooling fan provided in an axial direction end portion of the rotor and rotated integrally with the rotor;
• a housing, having an air intake provided opposing the cooling fan in an axial direction end portion, an annular rib provided adjacent to the air intake, and a discharge port provided across the annular rib, that houses the rotor and the stator and rotatably supports the rotary shaft;
• and
• a stay provided on a radial direction outer periphery of the housing, wherein
• the annular rib has an inner diameter side inclined cylindrical face, which inclines so that a diameter thereof becomes gradually smaller toward an inner side of the housing from an axial direction outer side end face of the air intake, and
• a sealing portion is provided between the stay and the annular rib.
