To provide a technology which enables a radial dimension of a vehicle drive transmission device to be reduced easily in a structure in which a switch mechanism for switching a shift stage includes a first engagement device and a second engagement device.SOLUTION: An input member 1, a second transmission shaft 3, a transmission 4, and a transfer 5 are disposed on a first axis X1, and a first transmission shaft 2 is disposed on a second axis X2. A switch mechanism 42 of the transmission 4 includes: a first gear G1 which integrally rotates with a third rotation element E3; a second gear G2 which integrally rotates with a first rotation element E1 or a second rotation element E2; a third gear G3 which interlocks with the first gear G1; a fourth gear G4 which interlocks with the second gear G2; a first engagement device 6 which connects or disconnects power transmission between the third gear G3 and the fourth gear G4; and a second engagement device 7 which selectively fixes the third gear G3 to a non-rotation member NR. The third gear G3, the fourth gear G4, the first engagement device 6, and the second engagement device 7 are disposed on a third axis X3 which is a different axis parallel to the first axis X1 and the second axis X2.SELECTED DRAWING: Figure 1
