点検できる。1 is a front view of the embodiment, and FIG. 2 is a plan view of FIG. Those given the same reference numerals as in the conventional example have approximately the same function. In the figure, a fan cover 3 having a wind hole 3b on an end face 3a that covers an outer fan (not shown) is provided on the opposite side of the rotating electric machine 2 of a vertical type fully-closed outer fan shape with the shaft end 1 facing downward, and a plurality of axial covers. A drip-proof cover 4 having mounting legs 4a and parallel to the end surface 3a is provided, and the fan cover 3 is attached to the rotating electric machine 2 with screws 5. As a characteristic structure of the embodiment, a U-shaped locking portion 10 that is elastically engaged with the air hole 3b of the fan cover 3 is provided at the tip of the mounting leg 4a. According to such a structure, the mounting legs 4 of the drip-proof cover 4 are
The U-shaped locking portion 10 provided at the tip of a is the fan cover 3
Since the air holes 3b are elastically engaged with each other, the drip-proof cover 4 can be easily attached and detached from the fan cover 3 by hand. Therefore, the rotation direction of the outer fan can be inspected without removing the fan cover 3.
