To provide a load fastening machine in which load fastening operations are simple and the handling of a winding side belt is also easy.

In a load fastening machine in which a body 1 and an operating lever 2 are connected through a winding-fastening shaft 3 and a winding side belt 42 is wound around the winding-fastening shaft 3, a winding mechanism 5 is attached to the operating lever 2 and the winding side belt 42 is wound around the winding mechanism. A handle 52 of a winding shaft 51 of the winding mechanism 5 is formed separately from the winding shaft 51. Both the handle and the winding shaft are connected through a suitable static frictional force, and when a force over the frictional force is applied, the handle 52 is structured to run idle.
