Claims

[Scope of utility model registration request]

A torsion spring having a shaft having an eccentric hole, a torsion spring that is fitted onto the shaft, and has a holding part that is secured to the shaft at one end and to the mounting wall surface at the other end, and is rotatable via a bearing on the outer periphery of the shaft. The tensioner is for a belt under the cock, and comprises a pulley held by the torsion spring, and the shaft is rotated around the eccentric hole to bring the pulley into pressure contact with the belt under the cock, and the tensioner is operated at a balanced position. A tension for a gogged belt, characterized in that a locking groove is formed on the front end surface of the shaft for positioning the shaft so that it does not rotate when the shaft is fixed.
