摘要

An alternator slip ring device according to this invention comprises: a shaft rotatably supported by a front bracket and a rear bracket and having a rotor disposed on the inner circumferential side of a stator; a sleeve fixed to the end portion of said shaft on the side of said rear bracket; and a conducting ring held on the outer circumferential side of said sleeve and connected to an excitation coil of said rotor. The alternator slip ring device is equipped with: a partition ring having a first flange provided on the outer circumferential side of said sleeve and having one end fixed to said rear bracket and the other end projecting in an outer diameter direction; a second flange provided on the anti-rear-bracket-side of said sleeve and having a ring wall forming a recess portion so that the other end of said partition ring is positioned, said ring wall having an end surface facing said first flange of said partition ring; and a flat portion formed on the outer circumferential portion of said ring wall of said second flange to be used for positioning during conveying.
