を特徴とする回転電機の整流子。In a commutator formed by alternately arranging a plurality of commutator pieces and a mica squid between the pieces to form a cylindrical shape and filling a molding material through a mold, the outer dimensions of the mica between the pieces are set as the commutator. A V-shaped groove is provided on the end surface of the mica between the commutator piece and the piece on the opposite riser side so as to be a certain dimension lower than the height of the piece and fit into the ■-shaped protrusion provided on the side opposite to the riser of the mold. A commutator for rotating electric machines featuring:
