In a transmitting system for a small-sized vehicle in which a crankshaft (2) of an engine (E) and an input shaft (10) of a multi-stage transmission (M) are connected to each other through a fluid transmitting device (T), a shifting clutch (Cc) is interposed between the crankshaft (2) of the engine and the multi-stage transmission in a series relation to the fluid transmitting device. A lock-up clutch (Lc) is interposed between a pump impeller and a turbine impeller of the fluid transmitting device (T). Thus, when the multi-stage transmission (M) is to be shifted, the shifting operation can be conducted lightly, in spite of a creep phenomenon of the fluid transmitting device (T), by bringing the shifting clutch (Cc) into an OFF state. Moreover, during cruising of the vehicle, the slipping of the fluid transmitting device (T) can be inhibited by the OFF state of the lock-up clutch (Lc) to enhance the transmitting efficiency. |
