Zusammenfassung:PROBLEM TO BE SOLVED: To transmit turning force effectively by absorbing eccentricity automatically and connect a driving shaft and a driven shaft even if the driving shaft and the driven shaft are eccentric. SOLUTION: This power transmission transmits turning force from a driving shaft to a driven shaft, and is provided with a first disk-shaped member disposed on the driven shaft, a supporting shaft disposed on a fixing member, a second disk-shaped member supported rotatably by the supporting shaft, a connecting portion connecting the driving shaft and the second disk-shaped member, and a belt-shaped member stretched around the first disk-shaped member and the second disk-shaped member to transmit the turning force from the second disk- shaped member to the first disk-shaped member. The second disk-shaped member is supported in a way to displace freely to a radial direction in a specified amount, which is predetermined in correspondence with a maximum eccentricity amount between the supporting shaft and the driving shaft.
