PURPOSE: To perfectly seal the oil a casing until a second rotary shaft is connected and surely supply oil to a connection section after the connection of the second rotary shaft. CONSTITUTION: The lip of a seal body is slidably brought into contact with the internal surface of a casing 1 with a right output shaft 25 disconnected to seal between a medium shaft 21 and the casing 1 by the seal body. In the case where one end section 26 of the right output shaft 25 is fitted to one end 22 of the medium shaft 21, the end section 26 of the right output shaft 25 presses the projection of the seal body, resulting in the separation of the lip from the internal surface of the casing 1, producing a gap between the internal surface of the casing 1 and the medium shaft 21, allowing the oil in the casing 1 to flow to a fitting section side. Until the right output shaft 25 is connected, the oil in the casing 1 is perfectly sealed, and after the connection of the right output shaft 25, oil is surely supplied to the connection section. |
