To provide a breather device of a drive mechanism which inhibits diffusion of oil splash occurring in a drive mechanism and enables gas-liquid separation of the oil splash and air to be efficiently performed in a limited space.SOLUTION: A breather chamber 51 comprises a first breather space 51M at a center case body 21M side and a second breather space 51R at a right case body 21R side. The breather device of the drive mechanism includes: a first partition wall 52M forming the first breather space 51M with a center case body upper part; a second partition wall 52R forming the second breather space 51R with a right case body upper part; a breather chamber inlet part 51a formed by an offset between an opening of the first breather space 51M formed by the first partition wall 52M and an opening of the second breather chamber 51R formed by the second partition wall 52R; and a lower surface of the first partition wall 52M and a lower surface of the second partition wall 52R formed in an arc shape along an outer periphery of a ring gear 31 disposed below the breather chamber 51.SELECTED DRAWING: Figure 3

    【課題】駆動機構内で発生したオイル飛沫の拡散を抑制すると共に、限られたスペースの中でオイル飛沫と空気とを効率的に気液分離する駆動機構のブリーザ装置を提供すること。【解決手段】ブリーザ室51が、中央ケース体21M側の第1のブリーザ空間51Mと右ケース体21R側の第2のブリーザ空間51Rとから構成され、中央ケース体上部とともに第1のブリーザ空間51Mを形成する第1の隔壁52Mと、右ケース体上部とともに第2のブリーザ空間51Rを形成する第2の隔壁52Rと、第1の隔壁52Mにより形成される第1のブリーザ室51Mの開口部と第2の隔壁52Rにより形成される第2のブリーザ室51Rの開口部とのオフセットにより形成されるブリーザ室入口部51aと、ブリーザ室51の下方に配置されたリングギヤ31の外周に沿って円弧状に形成された前記第1の隔壁52Mの下面及び第2の隔壁52Rの下面と、を備える。【選択図】図3
