防止機構。 In an oil leak prevention mechanism for a bearing case, the oil leakage prevention mechanism for a bearing case includes a shaft penetrating a wall surface of the bearing case, and a two-stage oil draining labyrinth provided in a hole on the case side through which the shaft passes from the inside of the case to the outside. The gap between the inner oil drain labyrinths is set to be larger than the gap between the inner oil drain labyrinths, and a small room is provided between the two oil drain labyrinths by forming a ring groove on the inner peripheral surface of the hole in the bearing case. An oil leak prevention mechanism for a bearing case, characterized in that a suction pipe connected to a suction device is connected to a small room.
