The purpose of the present invention is to prevent a cooling liquid in a motor chamber from mixing with a lubricating oil in a gear chamber. A seal structure of a drive device is provided which includes a case in which a motor chamber for accommodating an electric motor and a gear chamber for accommodating a gear mechanism are located adjacent to each other, a partition that separates the motor chamber and the gear chamber, a bearing that supports a rotating shaft, a seal part that seals between the rotating shaft and the partition, a lubricating oil that lubricates the gear mechanism, and a coolant that cools the electric motor, and also includes a first bearing on the motor chamber side, a second bearing on the gear chamber side, a first seal part on the motor chamber side, a second seal part on the gear chamber side, and at least the second seal part of the first seal part and the second seal part is provided between the first bearing and the second bearing.

    本发明的目的在于使马达室内的冷却液与齿轮室内的润滑油不混合。一种驱动装置的密封构造,所述驱动装置具备:壳体,相邻地设置有收纳电动机的马达室和收纳齿轮机构的齿轮室;分隔壁,将马达室和齿轮室分隔;轴承,支承旋转轴;密封部,对旋转轴与分隔壁之间进行密封;润滑油,对齿轮机构进行润滑;以及冷却液,对电动机进行冷却,其中,所述驱动装置的密封构造具备马达室侧的第一轴承、齿轮室侧的第二轴承、马达室侧的第一密封部、以及齿轮室侧的第二密封部,第一密封部和第二密封部中的至少第二密封部设置于第一轴承与第二轴承之间。
