<P>PROBLEM TO BE SOLVED: To provide a lubrication structure of a power transmission device for reducing stirring resistance and supplying a suitable amount of oil to a lubrication part according to rotation speed of gears. <P>SOLUTION: The structure, comprising a first gear 1, a second gear 2, and a case 3, is composed to supply the oil L to an engagement part of the first gear 1 and the second gear 2 by stirring the oil L collected at a lower part of the case 3. The case 3 is characterized by comprising an oil inflow port 3r and also comprising an oil amount adjusting member 4 for adjusting an amount of oil stirred by the second gear 2. The oil amount adjusting member 4 is composed to increase flow rate of the oil L circulating between an upper part pf the oil amount adjusting member 4 and a lower part of the second gear 2 by contraction and deformation due to pressure of the oil L when the oil L is stirred by the second gear 2. <P>COPYRIGHT: (C)2010,JPO&INPIT |
