Transmission for hybrid vehicle

A transmission for hybrid vehicle includes a change-speed gear assembly (4), an engine-side connector (5), and a motor-side connector (6). The change-speedgearassembly (4) includes drive gears and driven gears making change-speed stages. A specific drive gear (45D) of the drive gears, and a specific driven gear (45F) of the driven gears, making a specific change-speed stage (e.g., the fifth-speed change-speed stage) of the change-speed stages, are made switchable between the idling state and the rotary connection state. The engine-side connector (5) switches the other drive gears and driven gears, making the other change-speed stages, between the idling state and the rotary connection state, respectively. The motor-side connector (6) includes a motor-side drive gear (61) meshing with a motor-side driven gear (45D) doubled as the specific drive gear (45D). The motor-side connector (6) switches the specific drive gear (45D), and the specific driven gear (45F) between the idling state and the rotary connection state, respectively.
