NON-PNEUMATIC TIRE

Document Type and Number:

WIPO Patent Application WO/2015/072314

Kind Code:

A1

Abstract:

Provided is a non-pneumatic tire in which elastic connecting plates (21) and (22) comprise a plurality of curved sections (21d)-(21f) and (22d)-(22f) that are curved in the circumferential direction of the tire and that are formed along a direction of extension in which the elastic connecting plates (21) and (22) extend in a side view of the tire so that the curving directions of said curved sections reverse in an alternating manner in the direction of extension. Extended sections (21i) and (22i) are provided to the elastic connecting plates (21) and (22) so as to extend across both the outer curved sections (21e) and (22e) and the inner curved sections (21d) and (22d), and said extended sections (21i) and (22i) have positioned thereon inflected sections (21g) and (22g) that are provided between the outer curved sections and the inner curved sections. The extended sections (21i) and (22i) extend along a reference line that has a larger curvature radius than the outer curved sections (21e) and (22e) and the inner curved sections (21d) and (22d) in a side view of the tire, and extend from one end section (21a) and (22a) of the elastic connecting plates (21) and (22) that is connected to an outer cylinder (13) to at least a central section along the direction of extension.
