Claims

[Scope of utility model registration request]

a pair of rollers arranged at a predetermined interval;
A belt wound and tensioned with both ends positioned between these rollers, a shaft that supports the one roller movably in the axial direction, and a support member that pivotally supports one end of this shaft. a swinging member that supports the other end of the shaft at an intermediate portion so that the shaft can swing around the support member; and a tip of the swinging member that abuts one end of the one roller. established as
a cam member that swings a swinging member so that when the roller moves in a direction opposite to the direction of shift on the shaft based on the shift of the belt, the tension of the belt is adjusted; A belt offset correction device, characterized in that the cam member is provided with a spring that biases the tip end of the swinging member so that it always abuts against the tip end of the swinging member.
