Thus, airflow resistance is increased by the diffusers, and the cooling air cannot be efficiently discharged from discharge ports provided circumferentially in an outer peripheral portion of a housing. Further, a stator coil cannot be sufficiently cooled. An electrical rotating machine includes: a rotor having a cooling fan on an end face of the rotor; a stator that is arranged opposite the rotor and has a stator coil with a rotation clearance provided between the stator and the rotor; a housing that holds the rotor and the stator; a plurality of intake ports that are provided in a side wall portion of the housing; a plurality of discharge ports that are provided circumferentially in an outer peripheral portion of the housing; and a plurality of diffusers that are provided circumferentially on an inner wall surface of a corner portion of the housing, the diffusers inclining toward the side opposite to a rotational direction of the rotor.

摘要： The invention concerns with connection of a lead from an electrical component of an alternator for a vehicle, and provides a terminal shape suitable for TIG welding (arc welding using a gas shielded non-consumable electrode) without being affected by dimensional accuracy of terminals to be connected to each other. Cross-shaped projections having a larger volume than a welded region of the terminal is provided near the welded region, and weld penetration (welding depth) is controlled based on a difference in heat capacity resulting from the volume difference, or melting is suppressed with promotion of heat radiation. Thus, the welding depth is stabilized without being affected by dimensional accuracy of the terminals including relative positions between them, and an alternator for a vehicle can be provided in which a lead from an electrical component has high connection reliability.
