A device for winding a spiral spring to start an engine of a construction such that a pedal shaft and a driving sprocket which is supported on the pedal shaft are connected each other in a freely rotatable manner through a clutch which is engaged and disengaged in accordance with forward and reverse rotations of the pedal shaft, that a ratchet pawl which permits the forward rotation of the pedal shaft and prevents the reverse rotation thereof is caused to be engaged with the outer peripheral teeth of the driving sprocket, and further that the driving sprocket and a driven sprocket which is provided on a starter shaft to be connected with a spiral spring are interlinked by a power transmission chain so as to cause the spiral spring to be wound around the starter shaft at the time of the forward rotation of the driving sprocket. |
