Claim:
A lubricating system adapted to supply lubricating oil to a lip portion of an oil-seal member for preventing the lubricating oil from leaking out of a case, the lubricating system comprising: a rotating member configured and arranged to be rotatably housed within the case and to slidably engage the lip portion of the oil-seal member, the rotating member including a boss part mounted to the rotating member; a bearing rotatably supporting the rotating member, the bearing including an inner race coupled to an outer circumferential surface of the boss part of the rotating member, an outer race configured and arranged to be coupled to the case, and a smoothing member interposed between the inner race and the outer race to smooth a relative rotation between the inner race and the outer race; a scraping member configured and arranged to scrape the lubricating oil discharged from the bearing, the scraping member including a fin part disposed in a position corresponding to a discharge part at which the lubricating oil is discharged from the bearing after the bearing has been lubricated, and a fixing part elastically contacting the boss part of the rotating member so that the fin part rotates integrally with the rotating member; and a guiding section configured and arranged to guide the lubricating oil scraped by the scraping member to the lip portion of the oil-seal member.
