置。 In a power lawn mower in which a drive belt is stretched between the drive pulley that transmits engine power to a drive pulley and rotates the cutter blade or wheel, the tension of the belt is adjusted inside the drive belt. A lever equipped with a tension roller that turns on and off the transmission of engine power to the driven pulley is disposed at the drive belt, and the tension roller applies an outward spreading force to the belt on the outside of the drive belt. A tensioning device for a driving belt of a power-powered lawnmower, characterized in that an idler is arranged to prevent the belt from spreading outward when the lawnmower is in use.
