ある。As described above in detail, according to the present invention, three first to third rotating shafts are arranged in the transfer case, and gears are provided on the second rotating shaft and the third rotating shaft. And a second rotating shaft and a third rotating shaft.
An oil garter part for collecting the oil scraped up by the two gears is provided above the respective gears arranged between the rotary shaft and the second and third rotary shafts, and is collected by the oil garter part. The bearings of the second rotating shaft and the third rotating shaft are lubricated by the oil that has been collected, and the oil garter portion is provided with a first collecting plate at an edge portion of the third rotating shaft. And the second collecting plate is erected at the edge portion of the second rotating shaft, so that the scraped oil of the gears arranged on the second and third rotating shafts is 2 The collection plate can be collected by the oil garter part installed upright, a large amount of oil can be collected, and the bearing parts of the second and third rotating shafts can be reliably lubricated, and the lubrication performance can be improved. , After collecting the oil for scraping up the gears of the second and third rotating shafts, Second, the bearing portion of each of the third rotation shaft can be lubricated, can unify oil gutter portion, and obtained a simplified configuration can reduce the cost, it is economically advantageous.
