Driving belt and manufacturing method thereof

A manufacturing method of a driving belt comprising:

• a plurality of first elements juxtaposed in a same orientation;
• and
• a hoop fastening the first elements in loop form,
• wherein the first element includes
• a first saddle surface to which an inner peripheral surface of the hoop is contacted,
• a pair of hook sections erected on each end section of the first saddle surface while protruding respectively toward a width center of the first element to cover end sections in a width direction of the hoop,
• a first boss projecting from a front surface of the first element, and
• a first dimple recessing to the inside from a rear surface of the first element,
• the first boss and the first dimple fit together to form an array of the first elements, and
• an opening width between the hook sections is narrower than a width of the hoop,
• the manufacturing method comprising:
• fitting a predetermined number of the first elements that is at least one piece shorter than a total required number of the elements with the hoop by letting through the hoop between the hook sections;
• fitting the first boss of the first element into the first dimple of the adjacent first element;
• inserting a second element between the adjacent first elements already fitted with the hoop from an inner circumferential side of the hoop;
• disposing the hoop on a second saddle surface of the second element by letting the hoop through an opening between a pair of pillars erected on each end section of the second saddle surface;
• and
• thereafter fitting a second boss of the second element into the first dimple of the adjacent first element, and fitting a second dimple of the second element onto the first boss of another adjacent first element.
