Hybrid driving device

A hybrid driving device comprising:

• a first input that is linked to an internal combustion engine;
• a rotary electric machine;
• a transmission that changes a speed of rotation of a second input, and transmits the rotation to an output;
• a rotor support which rotates integrally with a rotor of the rotary electric machine;
• a first engagement device;
• a second engagement device;
• and
• a case, wherein:
• the first engagement device links or separates the first input and the second input to and from each other in accordance with a state of engagement of the first engagement device regardless of a state of engagement of the second engagement device,
• the second engagement device links or separates the rotor support and the second input to and from each other in accordance with a state of engagement of the second engagement device regardless of a state of engagement of the first engagement device,
• the rotor support includes a supporting tubular portion having a tubular shape that supports an inner circumferential surface of the rotor of the rotary electric machine from a radially inner side, and the first engagement device and the second engagement device are disposed on the radially inner side relative to the supporting tubular portion,
• the case has a tubular case boss portion,
• the second input includes an input tubular portion having a tubular shape that is disposed on a radially outer side of the case boss portion,
• both of the first engagement device and the second engagement device are engagement devices which are operated by a hydraulic pressure, and which are respectively provided with an oil chamber, and
• the input tubular portion supports a first oil chamber forming member which is a member that forms the oil chamber of the first engagement device, and a second oil chamber forming member which is a member that forms the oil chamber of the second engagement device.
