In a belt tensioning device in which the distance between the rollers is maintained constant, a swing rod is rotatably supported on a shaft "A" provided on a part of a roller plate that connects the rollers, and other parts of the swing rod are supported. The end of the belt tensioning device is rotatably supported on a rotating shaft "B" fixed on a chain stay near the roller plate at a position between the roller plate and the driving pulley. (2) A bracket fixed to the flat part of one end of the chain stay near the driven pulley is extended along the chain stay toward the driving pulley, a hole provided at its tip is used as a rotation axis, and the swing rod is fixed to this hole. The belt tensioning device according to claim 1, comprising: (3) The belt tensioning device according to claim 2, wherein the bracket is made of sheet metal, is welded to the back side of the chain stay, and has a hole provided in a part of the bracket for fixing the chain case. (4) The rotating shaft "B" is provided at one end of a bracket that is not fixed to the bicycle frame, and the bracket is fitted onto the axle of the driven pulley and tightened with a hub nut, and has a convex portion to prevent rotation. 4. The belt tensioning device according to claim 1, wherein said bracket is provided with said bracket so as to come into contact with the upper or lower part of the chain stay. (5) Hole "A" on the roller plate is located on the belt side that is slacker than the middle of the two rollers, and is in relation to the straight line "C" connecting the center of the driving pulley and the center of the driven pulley. 5. A belt tensioning device according to claim 1, wherein the swing rod is inclined downward.
