Provided is a transmission for a hybrid vehicle which permits a compact, lightweight structure and yet allows the power of an internal combustion engine to be disconnected and which is capable of efficiently transmitting power without complicating the control. The transmission includes a speed changing unit which has a first input shaft 3 connected to a power shaft 6 of an internal combustion engine 1 and a second input shaft 4 connected to a power shaft of a motor 2 and which establishes a plurality of gear shift stages. A one-way clutch 7 is interposed between the power shaft 6 of the internal combustion engine 1 and the first input shaft 3. The one-way clutch 7 disengages the connection between the power shaft 6 of the internal combustion engine 1 and the first input shaft 3 when the rotational speed of the power shaft 6 of the internal combustion engine 1 is lower than the rotational speed of the first input shaft. 3. |
