To solve problems with a transmission device for drivingly linking the axle drive units disposed one behind the other with a motor interposed therebetween on a vehicle such as a carrying vehicle, wherein a large space is required for taking out power from a transmission starting end section and the vibration and noise propagating from a power taking out unit to a body frame during traveling are considerably large, and when various power taking out directions are set, in particular, it is difficult to standardize a power taking out casing because at least changing a structure for mounting on the body frame is indispensable.

The power taking out casing 82 accommodating the transmission starting end section 23 of the transmission device 2 is disposed in a fixed condition in a PTO support section 21a pivotably supporting a PTO shaft 50 in a housing 19 via an intermediate casing 81 adjusting the posture of the power taking out casing 82 with respect to the PTO support section 21a.
