PURPOSE:To prevent an abnormal temperature rise of lubricating oil by scraping up lubricating oil in a transfer case by a tooth surface to be fed into a lubricating oil collecting chamber and lubricating a rotary sliding portion through a supply pipe when the internal pressure in the transfer case increases. CONSTITUTION:When gears 5, 6 built in a front transfer case 2 are driven, lubricating oil scraped up to be carried in the rotating direction is continuously fed into a lubricating oil collecting chamber 10 disposed at the upper portion of a partition wall 9 and filled therein. During operation, when the pressure in the transfer case 2 increases, lubricating oil in the collecting chamber 10 is supplied to a bearing 7 separating from the lubricating oil lever according to an increase in pressure through a supply pipe 13. Thus, the lubricating oil is kept from generating heat due to a large oscillation or collision in its supply process, so that abnormal temperature rise can be prevented.
