    • A breather device for speed−change devices adapted to communicate the space in a speed−changer case (1) with the open air, comprising a vent port (10) formed at a position longitudinally deviated from an intermediate position, particularly the axial middle position, in the top of the speed−changer case axially of the case, the vent port being opened to the open air through a vent means (2) extending in the direction opposite to the direction of deviation. Thereby, the combination of the longitudinal deviation of the position of the vent port from the longitudinal middle portion of the speed−changer case and the direction of vent means facing opposite to that direction ensures that when the vent port position is tilted in a direction away from the oil level, the front of the vent means lowers and that, reversely, when the vent port position is tilted in a direction toward the oil level, the front of the vent means rises; thus, the occurrence of breathing is prevented for both the forward tilt and the rearward tilt of the speed−changer axis.
    • 一种用于变速装置的通气装置,其适于使变速箱(1)中的空间与敞开的空气连通,包括形成在纵向偏离中间位置,特别是轴向中间位置的位置处的排气口(10) 在壳体轴向的变速箱的顶部,排气口通过沿与偏离方向相反的方向延伸的排气装置(2)向敞开的空气敞开。 因此,排气口的位置与变速箱的纵向中间部分的纵向偏离和与该方向相反的排气装置的方向的组合确保了当排气口位置沿着远离方向倾斜时 从油位开始,排气装置的前部下降,而当排气口位置朝向油面方向倾斜时,排气装置的前部升高; 因此,对于变速器轴的向前倾斜和向后倾斜都防止呼吸的发生。
