PROBLEM TO BE SOLVED: To arrange a damper for absorbing the vibration of a power transmission system of a vehicle without causing interference with a peripheral vehicle-side member between a pair of universal joints on a drive shaft.SOLUTION: A drive shaft 10 comprises: a first universal joint 21 arranged at the other end of a first power transmission shaft 11 which is connected to a power source 2 at its one end; a second universal joint 22 arranged at the other end of a second power transmission shaft 12 which is connected to a drive wheel 28 at its one end; a third power transmission shaft 13 which extends toward the second universal joint 22 from the first universal joint 21; a fourth power transmission shaft 14 which extends toward the first universal joint 21 from the second universal joint 22; and a damper 30 which accommodates a shaft part 50 arranged at the other of the third and fourth power transmission shafts 13, 14 into a cylinder part 32 which is arranged at either of the third and fourth power transmission shafts 13, 14, and in which an elastic member 60 is interposed between the cylinder part 32 and the shaft part 50. A portion at the second universal joint 22 side rather than the elastic member 60 in the damper 30 is formed into a small-diameter part 36. |
