体を減少させたことを特徴とする。In order to achieve this object, the present invention provides a slip ring cover covering a current collector that extends axially from the part opposite the substantially central part of the slip ring to at least the lower part of the cooling gas popular part of the slip ring cover. , a ventilation guide extending to the vicinity of the slip ring is provided to reduce the amount of cooling gas that is directly exhausted without cooling the slip ring or brush.
以下、本発明の一実施例を第３図ないし第５図について
説明する。Hereinafter, one embodiment of the present invention will be described with reference to FIGS. 3 to 5.
図中、第１図および第２図と同一符号は同−物又は均等
物を示す。In the figure, the same reference numerals as in FIGS. 1 and 2 indicate the same or equivalent parts.

９が設けられている。As shown in FIGS. 3 and 4, the cooling air is
Cooling air that enters the slip ring cover 9 from the popular part 9
In a, there is an elliptical cylindrical ventilation guide 1 that surrounds the rotating shaft 10 and extends in the axial direction to the vicinity of the side wall of the slip ring 11.
9 is provided.

広い寸法に設定される。The gap between the inner circumferential surface of the ventilation guide 19 and the outer circumferential surface of the rotating shaft 10 is narrow enough to prevent the ventilation guide 19 from coming into contact with the rotating shaft 10 during operation at the lower part a1, and the gap between the inner circumferential surface of the ventilation guide 19 and the outer circumferential surface of the rotating shaft 10 is narrow enough to prevent the ventilation guide 19 from coming into contact with the rotating shaft 10 during operation. The ventilation guide 19 is set to have a wide dimension so that the inner circumferential surface of the ventilation guide 19 is located above the outer circumference of the slip ring.
したがって、人気側の通気管８から排気側の通気管１５
