PROBLEM TO BE SOLVED: To provide a power transmission device capable of improving mountability on a vehicle and twist resistance of a shaft.SOLUTION: A first cylindrical shaft 41 is coaxially arranged radially outside a counter shaft 23, and a second cylindrical shaft 42 is coaxially arranged radially outside the first cylindrical shaft 41. A first driven gear 33 is arranged at one end of the first cylindrical shaft 41 so as to mesh with a first drive gear 31, and a second driven gear 34 is arranged at one end of a second cylindrical shaft 42 so as to mesh with a second drive gear 32. A second engaged part 62 is arranged on the counter shaft 23. A second engaging part 72 is arranged at the other end of the first cylindrical shaft 41, and can connect the first cylindrical shaft 41 and the counter shaft 23 by engaging with the second engaged part 62. A third engaging part 73 is arranged at the other end of the second cylindrical shaft 42, and can connect the second cylindrical shaft 42 and the counter shaft 23 by engaging with the second engaged part 62. |
