<P>PROBLEM TO BE SOLVED: To provide a power transmission device that facilitates supply of lubricating oil to a connection part of a transmission side and a transfer side without spoiling the workability, even if the lubricating oil is enclosed in the transmission side and the transfer side independently. <P>SOLUTION: A power transmission device 1 includes: a transmission case 7 which accommodates a differential case 3 in which first lubricating oil 90 is enclosed; a transfer case 15 which accommodates the conversion mechanism 13 which includes a hollow shaft 11, and encloses a second lubricating oil 91 which is coupled with the transmission case; a plurality of first seal means for the first lubricating oil; a plurality of second seal means for the second lubricating oil; a space part 35 which is formed between the first seal means and the second seal means, and in which a coupling part 19 which couples a differential case and a hollow shaft are disposed; and a supply part 37 which occupies non-supply position until the hollow shaft rotates and occupies a supply position which supplies the second lubricating oil in the transfer case by rotation of the hollow shaft. <P>COPYRIGHT: (C)2012,JPO&INPIT |
