シヨン装置。 In an automatic tensioning device that absorbs elongation of a belt wound between pulleys, a tension spring 3 that urges a tension pulley 4 toward the belt is connected to a tension cam 1 at a connecting point 7, and the tension cam 1 is connected to the tension spring 3. The cam surface 1a, which is pivotally supported on the rotation support arm 5 of the pulley 4 by a pivot pin 6 and provided on the side opposite to the connection point 7 by sandwiching the pivot pin 6 of the tension cam 1, is attached to the cam surface contacting member 2. An automatic belt tensioning device characterized in that the connection point 7 at the tip of the tension spring 3 is maintained at a substantially constant position when the V-belt 12 is brought into contact with the V-belt 12 and extended.
