PROBLEM TO BE SOLVED: To suppress the leakage of lubricant from a breather pipe of a transmission. SOLUTION: The transmission 1 comprises a housing 6, the breather pipe 11 passing through a wall 6e of the housing 6, and a plurality of sealing plugs 12, 13, 14 fitted to the breather pipe 11. The sealing plugs 12, 13, 14 have vent holes 18, respectively. The vent holes 18 are arranged to be shifted to each other so that they are not overlapped with each other in view along a longitudinal direction S of the breather pipe 11. Air can distribute through the vent holes 18 into the breather pipe 11. The lubricant cannot move linearly in the breather pipe 11, and so the leakage of the lubricant is suppressed. The sealing plugs 12, 13, 14 each have simpler construction than a conventional valve. COPYRIGHT: (C)2008,JPO&INPIT
