Claims

[Claims for Utility Model Registration] 1. In a hollow part of a hollow rotating shaft that is rotatably supported by a bearing, one end is located at the rotating part and the other end is located at the end of the rotating shaft. Alternatively, in a cooling device for a rotating electrical machine comprising a heat pipe provided protruding from an end and a plurality of C1 heat radiation fins provided at the other end of the C heat pipe, the outer diameter of the heat radiation fin is defined as the inner side. 2. A rotary electric machine leg device for a rotating electrical machine, characterized in that the number of δ decreases in order from the heat fin to the outer heat radiating fin, and a vent hole is provided on the inner circumferential side of the heat radiating fin. 2. Dosei Electric Co., Ltd.'s cooling leg device according to claim 1, wherein the diameter of the cooling fins is gradually increased from the outer heat radiating fins to the V side heat radiating fins.
