Power transmitting device for vehicle

Providing a vehicular power transmitting system which includes a torque limiter device and which is configured to reduce deterioration of durability of a rotary member disposed between an engine and the torque limiter device. An inertia moment of a first rotary portion of a torque limiter device about its axis (first axis RC1) is smaller than an inertia moment of a second rotary portion about its axis (first axis RC1), so that an inertia moment of rotary members between an input shaft and the first rotary portion can be reduced as compared with that where the above-indicated inertia moment is larger than the inertia moment. Accordingly, the torque which transiently acts on a rotary member disposed between the engine and the torque limiter device, for instance, acts on the input shaft, during an operation of the torque limiter device, that is, during a slipping motion of the first rotary portion and the second rotary portion can be reduced, so that the deterioration of durability of the input shaft can be reduced.
