オルタネータ。An armature core around which an armature coil is wound and a field core around which a field coil is wound are fixedly arranged coaxially, and an inductor fixed to a rotating shaft is rotated between these pair of iron cores. In a brushless alternator configured to obtain AC output from an armature coil, a ring-shaped convex portion is formed on one of a casing that rotatably supports the rotating shaft via a bearing and a yoke of the inductor, and the other A concave portion is formed to receive the convex portion through a small gap, and the bearing is communicated with the space within the casing through a labyrinth formed by the gap formed between the convex portion and the concave portion.
