A spiral spring wheel includes a ring spring and a leaf spring assembly surrounding an outer surface of the ring spring. A shoe is placed over the leaf spring assembly. The shoe sidewalls extend past the leaf spring assembly and tuck under the ring spring. Each torsion spring in a first plurality of torsion springs extends in a clockwise spiral shape from a flange to an inner surface of the ring spring. Each torsion spring in a second plurality of torsion springs extends in a counterclockwise spiral shape from the flange to the inner surface of the ring spring.

A wheel includes a wheel rim, a hub defining a hollow housing for a wheel mount, and three or more resilient and equidistantly spaced spokes extending between an outer circumferential surface of the hub and an inner circumferential surface of the wheel rim. Each spoke is defined by a flexed, elongate spring element having a length that is greater than the radial distance between the outer circumferential surface of the hub and the inner circumferential surface of the wheel rim. The spring element is tangentially fixed at or towards one end to the outer circumferential surface of the hub and tangentially coupled at or towards its other end to the inner circumferential surface of the wheel rim via a hinged connection. The tangential coupling at the wheel rim is spaced circumferentially from the tangential fixing at the hub in a predetermined direction by a predetermined angle.

Provided is a non-pneumatic tire in which a plurality of curved sections (21d) to (21 f) and (22d) to (22f) curved inward in a tire circumferential direction are formed at elastic connecting plates (21) and (22) in an extension direction in which the elastic connecting plates (21) and (22) extend when seen in a tire side view such that curved directions are alternately opposite to each other in the extension direction, outer curved sections (21e) and (22e), inner curved sections (21d) and (22d), and extension sections (21i) (22i) extending throughout both of the curved sections and in which inflection sections (21g) and (22g) formed between both of the curved sections are disposed, are formed at the elastic connecting plates (21) and (22), and the extension sections (21i) and (22i) extend along reference lines having radii of curvature larger than that of the outer curved sections (21e) and (22e) and the inner curved sections (21d) and (22d) when seen in the tire side view and extend from first end portions (21a) and (22a) of the elastic connecting plates (21) and (22) connected to an outer tubular body (13) to arrive at a central portion in at least the extension direction.

A non-pneumatic tire includes a support structure for supporting a load from a vehicle. The support structure includes an inner annular portion, an outer annular portion concentrically provided outside the inner annular portion, and a plurality of connecting portions which connect the inner annular portion and the outer annular portion to each other and are provided in a tire circumferential direction independently of one another, and the plurality of connecting portions are configured such that elongated plate-like first connecting portions and elongated plate-like second connecting portions are arrayed along the tire circumferential direction, the first connecting portions being extended from one side in a tire width direction of the inner annular portion to other side in a tire width direction of the outer annular portion, and the second connecting portions being extended from other side.
