Provided is a vehicle AC generator which enables the common use of components and the use of the same molding die for molded bodies to enable a significant reduction in fabrication cost. The vehicle AC generator includes a molded body (45). On one surface side of the molded body, a capacitor body (43) including a capacitor element built therein is electrically connected to an insert conductor. On another surface side of the molded body, a resistor (44) is electrically connected to the insert conductor only when a device main body is provided outside of the AC generator, and the device main body is electrically connected to the insert conductor only when the device main body is provided in the AC generator.

A highly reliable rectifying device of a vehicle alternator capable of improving the vibration resistance of a diode. A connection lead 33d of a diode 33 included in a rectifying device includes a linear part 33f extended in parallel from a metallic base 33b, and a bent part 33g bent 90° or more substantially like an arc from the linear part 33f. The bending radius R of the bent part 33g is set to a value larger than a separation distance w in a horizontal direction between the terminal of the linear part 33f and the distal part of the connection lead 33d.

A rotor shaft is supported in a rotatable manner at both ends by bearings respectively disposed to a housing forming a part of a stator and provided with a positioning portion of the bearing in at least one shaft end. The positioning portion is formed of an annular step-like rise portion that abuts on a circular arc surface provided to an inner ring corner of the bearing. A rotor shaft capable of holding the bearing in a stable manner over a long period is thus obtained without increasing the number of components and the numbers of working processes and assembly man-hours for the shaft. It thus becomes possible to solve problems, such as an increase in cost due to a large amount of working margin and increases of the direct material cost and in weight due to a larger finishing diameter of the shaft.

A mixer drum driving device includes a mixer drum, a hydraulic motor, a hydraulic pump, an auxiliary hydraulic pump for rotating the mixer drum for mixing by supplying pressure oil to the hydraulic motor independently of the hydraulic pump, and a direct-current brush motor for driving and rotating the auxiliary hydraulic pump. The auxiliary hydraulic pump is driven and rotated by the direct-current brush motor when the engine stops during the rotation of the mixer drum for mixing.
