An improved engine starting device for a motorcycle of the kick pedal type is provided which is easy to operate, does not require any large force of operation and is thus particularly suitable for an unskilled and powerless person such as a woman or girl to operate. To this end, the device includes a spiral spring which is operatively associated with an engine crankshaft and with a pedal arm so that it can rotate the crankshaft for engine cranking by releasing its spring force or energy previously accumulated by several repetitive swing motions of the pedal arm due to the rider's foot operation. The device also provides improved safety in engine starting operation by preventing the motorcycle from starting to run unintendedly even where the engine is started with the engine throttle valve being opened excessively. For this purpose, release means, which is operable to cause the spiral spring to release its accumulated force or energy for engine cranking, is operatively connected with a manipulative member of a control system such as, for example, a brake mechanism or a clutch means, which acts to render the motorcycle inoperative, in a manner such that the former is caused to operate in response to actuation of the latter. |
