PROBLEM TO BE SOLVED: To provide a power train for preventing oil leakage from the inside of a case body of a transmission. SOLUTION: This power train 10 has the transmission 36, a propeller shaft 21 and an oil leakage preventive ring 81. The transmission 36 includes an output shaft 52 and an extension housing 39 for arranging the output shaft 52 together with oil and forming an opening 68. The propeller shaft 21 is connected to the output shaft 52 via the opening 68 for transmitting motive power from the transmission 36. The oil leakage preventive ring 81 is arranged at the output shaft 52, and arranged in a position X in the extension housing 39. The oil leakage preventive ring 81 is moved up to the position X from a position for blocking up the opening 68 by being pressed by the propeller shaft 21 when connecting the propeller shaft 21 to the output shaft 52.
