Abstract:
1. A power transmission mechanism comprising: a first casing structure defining an atmospheric chamber which is formed between a transfer and a transmission connected with the transfer, and which is opened to an outside; a second casing structure defining a transfer chamber receiving a transfer mechanism of the transfer, and defining a connecting passage through which the transfer chamber is connected to the atmospheric chamber; and a gas-liquid separating device interposed between the transfer chamber and the connecting passage so that the transfer chamber and the connecting passage are connected through the gas-liquid separating device, wherein the first casing structure includes a separating wall extending between the transfer and the transmission and separating the atmospheric chamber from a transmission chamber containing a transmission mechanism; and wherein the second casing structure includes a separating wall extending between the transfer and the transmission and defining the atmospheric chamber between the separating wall of the first casing structure and the separating wall of the second casing structure; and wherein each of the separating walls is formed with reinforcing ribs formed in the atmospheric chamber.
