Abstract
In a driving belt configured by binding a plurality of elements in loop form by a belt-like hoop, an opening width between a first hook section and a second hook section of the element is narrower than a width of the hoop; a first width from a center to a first pillar section is larger than a second width from the center to a second pillar section; a first clearance between a saddle surface and a lower surface of the first hook section, and a second clearance between the saddle surface and a lower surface of the second hook section, are larger than a thickness of the hoop; and there is formed a weight adjusting section by which a center-of-gravity position in a width direction of the element is positioned more to a first pillar section side than the center is.
Claims11
A driving belt configured by arranging a plurality of plate-piece shaped elements and binding the elements in loop form by a belt-like hoop, wherein
- the element comprises
- a base section forming a main body portion,
- a saddle surface formed at an upper end of the base section to contact an inner peripheral surface of the hoop,
- a first pillar section erected from the upper end of the base section at a first end section of the base section in a width direction of the element,
- a second pillar section erected from the upper end of the base section at a second end section of the base section in the width direction,
- a first hook section extending out from the first pillar section toward a center of the element in the width direction, and
- a second hook section extending out from the second pillar section toward the center,
- an opening width between a tip section of the first hook section and a tip section of the second hook section is narrower than a width of the hoop,
- a first width from the center to a base corner of the first pillar section is wider than a second width from the center to a base corner of the second pillar section,
- a first clearance between the saddle surface and a lower surface of the first hook section facing the saddle surface, and a second clearance between the saddle surface and a lower surface of the second hook section facing the saddle surface are both larger than a thickness of the hoop, and
- the element further comprises a weight adjusting section by which a center-of-gravity position of the element in the width direction is positioned more to a first pillar section side than the center is.
