Vehicle AC generator

A vehicle AC generator comprising:

• a frame including an end wall section and a peripheral wall section;
• a stator core fixed to an inner peripheral surface of the peripheral wall section;
• a stator coil constituted by a plurality of phase coils, the stator coil being wound around the stator core and having rear and front coil ends projecting axially rearward and frontward respectively from the stator core;
• a rotor located radially inwardly of the stator core and being rotatably supported by the frame;
• and
• a cooling fan having centrifugal blades and fixed to an end surface of the rotor;
• the peripheral wall section having a cooling air discharge opening adjoining the end wall section,
• the end wall section having a centrifugal-blade-facing portion axially facing the centrifugal blades, and a coil-end-facing portion axially facing the rear coil end,
• the coil-end-facing portion being bent at a predetermined curvature radius and extending from the centrifugal-blade-facing portion to the cooling air discharge opening,
• an inner end surface of the coil-end-facing portion being formed with a recess located axially rearwardly of a radial extension line of an inner end surface of the centrifugal-blade-facing portion,
• wherein the recess has a shape of circular arcs extending along a circumferential direction of the rotor,
• the rear coil end includes an axially projecting wiring section projecting axially rearward from a ring-like section thereof,
• the axially projecting wiring section is located in a clearance between the rear coil end and the inner end surface of the coil-end-facing portion, and
• the axially projecting wiring section includes a crossover wiring section connecting a plurality of partial coils constituting the phase coils to one another and a neutral wiring section connecting one ends of the phase coils to a neutral point.
