ようにしたことを特徴とするベルト伝動装置。 In a belt transmission device that winds a belt between a drive pulley and a driven pulley and presses the belt with a tensioner to generate belt tension, the tensioner includes a tension roller that presses the belt, and a tension roller that presses the belt. consisting of a tensioner arm which is pivoted at one end and whose other end is the center of rotation, and a tensioner spring which urges the tensioner arm to rotate in the direction of the belt,
The center of swing of the tensioner arm is disposed on the opposite side of the rotation axis of the tension roller across the center line between the two pulleys, and at the use limit position, the center of swing of the tensioner arm is located on the opposite side of the rotation axis of the tension roller. A belt transmission device characterized in that the tensioner arm is closest to a reference orthogonal line that is perpendicular to a virtual belt line and passes through the swing center.
