Abstract
A walk-behind working machine includes a motive power source, right and left transmission shafts, and a clutch for transmitting motive power from the source to the shafts. The transmission shafts are disposed in alignment with their respective ends butting against each other. The clutch includes a driving cylindrical member rotationally mounted around the transmission shafts. The transmission shafts have first grooves formed on their outer peripheral surfaces while the cylindrical member has second grooves formed on an inner peripheral surface thereof. The clutch further includes balls disposed between a space defined by the first and second grooves. The first groove is of substantially V-shaped configuration. The first groove has a leading end positioned between the ends of the transmission shafts.
