Vehicle drive transmission device

A vehicle drive transmission device comprising:

• an input member drivingly connected to an internal combustion engine;
• a differential gear device that includes a differential input gear and distributes rotation of the differential input gear to a pair of output members, each of the output members being drivingly connected to a wheel;
• and
• a gear mechanism that drivingly connects the input member and the differential input gear via a counter gear mechanism, wherein:
• a switching mechanism for switching between a transmission state in which a driving force is transmitted between the input member and the differential input gear, and a non-transmission state in which a driving force is not transmitted between the input member and the differential input gear is provided in the gear mechanism;
• the switching mechanism includes an axially moving portion that moves in an axial direction to switch between the transmission state and the non-transmission state;
• the axially moving portion includes at least one of a member that is arranged coaxially with the input member and moves in the axial direction, and a member that is arranged coaxially with the counter gear mechanism and moves in the axial direction;
• and
• a drive mechanism that drives the axially moving portion in the axial direction includes a drive portion that reciprocates a first member along an intersecting direction that is a direction that intersects the axial direction, a conversion portion that converts a reciprocating motion of the first member along the intersecting direction into a reciprocating motion of a second member along the axial direction, and a connecting portion for connecting the second member and the axially moving portion such that the axially moving portion reciprocates along the axial direction as the second member reciprocates along the axial direction.
