Inventor: MIZUKOSHI YUKIO
IPC: B60K17/04
Filed: 1980-12-26
Abstract: PURPOSE: To markedly shorten the time for oil injection by forming the oil circulating hole which communicates to the upper and the lower chambers.  
     CONSTITUTION: When oil is pour into the carrier 9 of a driving apparatus D from the oil injection port 20 formed on the side wall of the upper chamber 16 of the carrier 9, the oil which flows into the upper chamber 16 flows down smoothly into the lower chamber 17 from an oil circulating hole 21. After the lower chamber 17 is filled with oil, oil is pourted-in to the degree in which a reduction ilder gear 11 and a reduction output gear 12 are immersed. When the driving apparatus D is started in the state sufficiently injected with oil, the oil in the lower chamber 17 is agitated by a drive pinion 13 and a drive gear 14, and heat exchange prescribed before can be performed.
