Hybrid drive device

A hybrid drive device comprising:

• an input member to be drive-connected to an internal combustion engine;
• a first rotating electric machine arranged on a first axis;
• a second rotating electric machine arranged on a second axis parallel to and different from the first axis;
• an output member to be drive-connected to a wheel;
• and
• a power transmission mechanism that transmits drive force among the first rotating electric machine, the input member, the second rotating electric machine, and the output member, wherein
• one of the first rotating electric machine and the second rotating electric machine is defined as a target rotating electric machine,
• an axis on which the target rotating electric machine is arranged is defined as a target axis, a direction parallel to the target axis is defined as an axial direction, and a direction perpendicular to the target axis is defined as a radial direction,
• the power transmission mechanism is arranged on a first axial side being one side in the axial direction with respect to the target rotating electric machine,
• the power transmission mechanism includes a meshing type engagement device,
• the engagement device includes:
• an engagement member that is arranged on the first axial side of the target rotating electric machine, and moves in the axial direction and thereby switches a state of engagement of the engagement member with a rotating member constituting the power transmission mechanism;
• and
• an engagement drive mechanism that drives the engagement member,
• the engagement drive mechanism includes an engagement drive source and an engagement power transmission mechanism that transmits drive force of the engagement drive source to the engagement member,
• the engagement drive source is arranged at a position that is on an outer side of the target rotating electric machine in the radial direction and that overlaps with the target rotating electric machine when viewed in the radial direction, and
• the engagement power transmission mechanism includes a transmission member extending along the axial direction, and is configured to drive-connect the engagement drive source and the engagement member to each other via the transmission member.
