Zusammenfassung:	PROBLEM TO BE SOLVED: To provide a belt transmission mechanism to be used as a clutch to switch forward and reverse of a small running vehicle driven by the engine of a walk type cultivator used in an agricultural field and reduce a cost and save a space. SOLUTION: Two clutch mechanisms are situated in parallel to the crank shaft 6 of an engine 5 and the input shaft 7 of a transmission 8. One belt tension clutch mechanism 20 brings a V-belt 23 and a tension pulley 25 into contact with each other or separation from each other and a power is transmitted to or cut off from forward rotation. The other belt back tension clutch mechanism 10 brings the back of a V-belt 13 into contact with or separation from a flat pulley 11 and a power is transmitted to or cut off from reverse rotation.
