ベルトテンシヨン装置。[Claims for Utility Model Registration] A fulcrum is a position close to a small pulley on a frame connected between two toothed pulleys, and an arm of approximately the same length is freely rotatable diagonally around this fulcrum via a spring. Installation: Attach an idler pulley to the end of one (tension side) arm, and a flat tension pulley to the end of the other (loose side) arm.
This timing belt tension device for a bicycle is characterized in that when a pedal is depressed, the tension side belt pushes an idler pulley downward, and at the same time, the flat tension pulley presses the back surface of the slack side belt to apply tension .

Claims

[Scope of utility model registration request]

The position near the small pulley on the frame connected between the two toothed pulleys is used as a fulcrum, and around this fulcrum, arms of approximately the same length are attached via springs so as to be able to rotate diagonally. A timing belt tension device for a bicycle, characterized in that a toothed idler pulley is attached to the tip of an arm, and a flat tension pulley is attached to the tip of the other (loose side) arm.
