PURPOSE:To perform the lubrication of a chain and a power transmitting member positioned below the chain by providing a chain lubricating hole on a sprocket positioned on the upper side and an oil receiving member between both sprockets. CONSTITUTION:Lubricating oil supplied to an oil conduit is sent to an oil chamber via a communicating hole, and supplied to a chain 83 through the lubricating hole of a driving side sprocket 81 positioned on the upper side. And, an oil receiving member 91 is so disposed between the driving side sprocket 81 and a driven side sprocket 82 as to receive the lubricating oil which is supplied from an oil hole provided on the driving side sprocket to lubricate the chain 83 and dropped after that, and the lubricating oil is supplied to a final speed reducer 50 and a differential apparatus 60. Accordingly, the lubricating oil supply to the contact area between the chain 83 and the sprockets 81 and 82 can be surely carried on and the lubrication of the final speed reducer 50 positioned below and the differential apparatus 60 can also be performed surely and easily.
