description PROBLEM TO BE SOLVED: To provide a dynamo apparatus which can prevent lubricating oil from being leaked to the outside of a casing and which can cool a bearing further effectively.SOLUTION: A dynamo apparatus 1 includes a bearing support bracket 8 having a channel 8a of lubricating oil which also functions as a cooling medium, lubricating oil circulation space S1 formed between the bearing support bracket 8 and a bearing 6, a partition wall 9 which is provided in a casing 2 and which partitions bearing-arranged space S2 in which the bearing 6 and the bearing support bracket 8 are arranged and cooling air circulation space S3 in which the cooling air circulates, an opening part 22g formed in the cooling air circulation space S3 side of a rising wall 22 connected to the bearing support bracket 8 of the casing 2, and a cooling air guide channel 22h which communicates with the opening part 22g and which guides the cooling air to the bearing support bracket 8.
