<p><P>PROBLEM TO BE SOLVED: To excellently suppress the leaking oil from being discharged out of a case through a breather mechanism well, while excellently lubricating an object well with leaking oil of an oil pump. <P>SOLUTION: In a power transmission device 20, a ventilation hole 42o which has an opening opposed to a transmission device 30 and communicates with a case side opening 60o of a breather plug 60, and an operating oil discharge hole 42a which guides a leaking oil of an oil pump 40 to a thrust bearing 76 which is to be lubricated, are formed at a pump cover 42 constituting the oil pump 40. An opening of the ventilation hole 42o is covered with a cover member 50 having a communication hole 51b which allows the interior of a transmission case 22 to be communicated with the interior of the ventilation hole 42o. The cover member 50 regulates blowing out of the operating oil toward the transmission device 30 from the operating oil discharge hole 42a. <P>COPYRIGHT: (C)2013,JPO&INPIT</p> |
