Claims

[Scope of utility model registration request]

A stator core formed by laminating a plurality of plate materials is configured such that a front bracket and a rear bracket are fitted to both ends of the stator core, and the stator core is fixed by tightening with a through bolt screwed into the front bracket from the rear bracket. In the vehicle alternator, the rear bracket and the front bracket are formed with abutting portions that abut each other on the outer diameter side of the stator core in an assembled state, and one of the leg pieces touches the side surface of the rear bracket of the stator core. A substantially U-shaped elastic holding plate is provided, the other leg of which contacts the bolt threaded portion of the front bracket side, and one leg of the elastic holding plate has an abutting portion of both brackets. Before the two brackets abut each other, the abutment part that abuts the bolt insertion part of the rear bracket is located outward from the stator core, and the abutment parts of both brackets are brought into contact with each other based on the screwing of the through bolts. An alternator for a vehicle, characterized in that the stator core is pressed and fixed by compressive deformation of an elastic holding plate until it abuts.
