Claims

[Scope of utility model registration request]

(1) A gasket is interposed between the first flange projecting outward from the vertical wall of the box-shaped upper cover and the second flange provided on the frame. In a rotating electric machine in which tightening is performed using a rotating electric machine, a wide groove is provided on the lower surface of the packing to form a thin wall portion, the lower edge of the first flange is brought into contact with approximately the center of the thin wall portion, and the first
A rotating electric machine characterized in that, when tightening of the second flange is completed, the thin wall portion is elastically deformed downward and comes into contact with the upper surface of the second flange.

(2) The rotating electrical machine according to claim 1, wherein the wide groove is divided into two parts at a part of the thin part of the packing due to elastic deformation of the thin part of the packing.
