PURPOSE:To eliminate a leak of lubricating oil, by forming a vent hole in a casing end face, making a baffle plate extend from the casing end face to the inside, while forming an air chamber in the outside of the vent hole, and connecting an air pipe to the air chamber. CONSTITUTION:A vent hole 9 is formed in an end face of a casing 10, while a baffle plate 13 is made to extend from the end face of the casing 10 to the inside so as to cover the scattering direction of lubricating oil, then an air chamber 16 is formed in the outside of the vent hole 9, and an air pipe 12, leading to the atmosphere, is connected to this air chamber 16. With this constitution, a possible flow of the lubricating oil into the air chamber 16 is checkable before it happens, so that a leak of the oil out of the air pipe 12 is surely precentable from occurring. |
