という欠点があった。A conventional example of an external fan-shaped rotating electric machine will be explained based on FIG. In this figure, an outer circumferential cover 2 surrounding an outer fan 1 is attached to the outer circumference of a bracket 4 fixed to an end surface of a frame 3 via a support part 4a, and one piece on the exhaust side of the outer fan cover 2 is attached to the support part 4a. A ring 6 that reduces the gap between the parts 5 and 5 is attached by bath welding, etc.
, in such a structure, the part of ring 6 is lost.
Not only tr q-, but also S without much effort required for bath contact work.
There was a drawback.

置に外扇カバー32の突出部32aを配設する。FIGS. 2 and 3 show the main parts of the fan-shaped rotating electric machine according to the present invention, and the parts shown in FIG. 1 and numbered iuJ-1 are the same parts. In the rotating electrical machine in (2.i. et al.'), a plurality of inward protrusions 32a are integrally formed in the circumferential direction at the exhaust side end of the outer L:l support cover surrounding the outer fan 1. The protruding portion 32+t is formed by providing a plurality of /J (circumferential partial cuts 32I) on the outer periphery of the exhaust side end of the outer fan cover 32 as shown in FIG. It is formed by extruding the provided end portion inward as shown in the figure 4. In order to provide an appropriate gap between the frame 3 and the outer circumference of the frame 3, the gap in the exhaust side opening 5 of the upper outer fan cover 32 is made so small that a finger cannot fit into it.
When a large number of radiating fins 33 in the axial direction are provided on the outer periphery of the fan cover 32, the protrusion 32a of the outer fan cover 32 is disposed at an intermediate position between adjacent radiating fins 33, as shown in FIG.

f: In Yu, the exhaust side opening of the external fan cover is configured so that a plurality of inward protrusions are extruded or cut and integrally formed in the circumferential direction at the exhaust side end of the external fan cover. The effect is that the gap between the parts can be made so small that a finger cannot fit into the protruding part without increasing the number of parts.
