POWER TRANSMISSION DEVICE

摘要

PROBLEM TO BE SOLVED: To provide a power transmission device that facilitates balance adjustment of a rotor of a motor/generator while having a small physical constitution.

SOLUTION: A rotor shaft 33 has: a shaft 331 formed at the end of the engine 11 side; a first cylindrical part 332 whose outer wall is fitted to an inner wall of a rotor 32; a second cylindrical part 333 forming a cylindrical space 34 in-between the outer wall of the shaft 331; and an annular part 334 connecting the inner wall of the first cylindrical part 332 and the outer wall of the second cylindrical part 333 to each other. A storage space 35 is formed on the engine 11 side of the annular part 334 between the first cylindrical part 332 and the second cylindrical part 333. At least a part of a clutch 50 is stored in the storage space 35. A housing 20 has a housing cylindrical part 222 cylindrically extending toward the engine 11 side in the space 34. A bearing 23 is provided between the outer wall of the housing cylindrical part 222 and the inner wall of the second cylindrical part 333 in order to bear the rotor shaft 33.
