Claims

[Scope of utility model registration request]

Rotation in which a gasket is interposed between a first flange protruding outward from a vertical wall of the box-shaped upper cover and a second flange provided at the top of the frame, and then tightened. In electrical equipment, a step-shaped protrusion is formed along the circumferential direction near the upper surface of the inner circumferential side of the above-mentioned patch, a narrow groove is provided on the upper surface of this protrusion, and a wide groove is provided on the lower surface opposite to the protrusion. , a hakama portion extending downward is formed on the outer edge of the packing, and the protruding lower edge of the upper cover is fitted into the thin groove of the packing, and the tightening of the first and second flanges is completed. When this occurs, the vicinity of the wide groove is elastically deformed downward and comes into contact with the upper surface of the second flange, and the seal portion on the upper surface of the packing is covered by the first flange in an eaves-like manner, and the seal on the lower surface is A rotating electric machine, characterized in that the part is covered in an eave-like manner by the hakama part of the jacket.
