摘要： An edger having a driving device for operating a rotary blade, the driving device including a driving pulley; a pulley to be driven; a driving belt arranged between the two pulleys; a swing arm having the center of its swinging motion at a position different from the center of rotation of the driving pulley; a rod slidably supported by the swing arm and supporting the pulley to be driven; a spring for urging the rod in a direction in which the distance between the shafts of the two pulleys is elongated; a drive-side pulley cover and a driven-side pulley cover. The belt is engaged/released by changing the distance between the shafts of the two pulleys by swinging the swing arm, the distance between the driven-side pulley cover and the pulley to be driven having a small value so as to induce contact between the pulley to be driven and the driving belt at the time of belt release, and belt inlet and outlet portions of the drive-side pulley cover being shaped and arranged to be closer to the driving belt when under tension than the intermediate portion of the drive-side pulley cover so as to release the driving pulley and the driving belt. Another embodiment of the edger includes a driven-side pulley cover having a slant portion for a sliding and pushing the driving belt to the side surface of a pulley groove of the pulley to be driven when the belt is loosened.
