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 parts that abut each other on the outer diameter side of the stator core in the assembled state, and one of the rear brackets has a bolt insertion part in the bolt insertion part of the rear bracket. A generally U-shaped elastic holding plate is loosely fitted so that one leg faces the bolt head of the through bolt and the other leg faces the side surface of the stator core, and both leg pieces of the elastic holding member are fitted. The opposing distance between the two brackets is set so that there is a gap between the bolt insertion part and one of the leg pieces facing the bolt head with the abutting parts of both brackets abutting each other. , for a vehicle, characterized in that the elastic retainer plate has a compression margin based on the screwing of the through bolt after both abutting portions abut, and the stator core is pressed by the compressive deformation of the elastic retainer plate. AC generator.
