    摘要： The invention relates to a vehicular alternator which can effectively utilize the magnetic flux of a permanent magnet (7) disposed between claw-type magnetic poles (5A, 5B) and can improve an output of the alternator. The vehicular alternator comprises a rotor (1) and a stator (2) constituted by coiling stator windings (15) over a stator core (14) the rotor (1) comprising a pair of claw-type magnetic poles (5A, 5B) arranged in an opposed relation a permanent magnet (7) disposed between adjacent two of a plurality of claws (5Aa, 5Ba) provided on the pair of claw-type magnetic poles (5A, 5B), and field windings (6) coiled radially inward of the plurality of claws (5Aa, 5Ba). Each of the plurality of claws (5Aa, 5Ba) of the rotor (1) is formed to have a shape coming into contact with the whole of a magnetic pole surface of the permanent magnet (7).
