PROBLEM TO BE SOLVED: To provide a propelling device for a vehicle, which suppresses noise and vibration in acceleration of a vehicle and enhances the acceleration response thereof. SOLUTION: The propelling device for a vehicle includes: an engine E as a driving power source for driving wheels RL and RR; and a transmission TM interposed between the engine E and the driving wheels to change the speed of output rotation from the engine and to transmit the rotation to the driving wheels. The propelling device further includes: two fly wheels FW1 and FW2 disposed on a driving shaft between the engine and the transmission; one of the two fly wheels being rotatably disposed on the driving shaft; a fly wheel clutch CL2 for connecting or disconnecting the fly wheel FW2 rotatably disposed on the driving shaft to or from the driving shaft; and a fly wheel clutch controlling means that controls to engage the fly wheel clutch when the engine is in a low rotation speed region having a rotation speed not more than a predetermined threshold, and to disengage the fly wheel clutch when the engine is in a high rotation speed region having a rotation speed higher than the threshold.
