Claims

[Scope of utility model registration request]

It is equipped with a toothed belt wheel and a toothed belt that meshes with the belt wheel, and reduces the air noise generated by the air trapped between the belt wheel and the belt when the belt wheel meshes with the belt wheel. In order to do so, an air release through hole is formed in the meshing portion of one of the belt pulley and the belt to allow air trapped between the belt pulley and the belt to escape from the meshing portion during meshing. A toothed belt type power transmission device characterized by:
