    Abstract: A rigidity measurement device of a tread ring comprises a support jig for detachably holding a tread ring unit. The support jig has an open part for deformably exposing a measurement area, which is one portion of the tread ring, to the exterior, and a restraining part for essentially non-deformably restraining a non-measurement area, which is an area other than the measurement area of the tread ring. The restraining part inhibits deformation of the non-measurement area, whereby stress is no longer generated in the non-measurement area and the rigidity of the measurement area alone can be measured.

    Abstract: An airless tire comprises: a tread ring having a tread, a hub located radially inside the tread ring, and cross radial members connecting the tread ring with the hub. The cross radial members include first radial members and second radial members crossing the first radial members. The length measured along the radial member is not more than 180% of the radial distance between the hub and the tread ring.

    Abstract: An air-less tire has, formed on a tread ring: tread rubber for forming a ground contact surface; an outer reinforcement cord layer provided nearest the tread rubber; an inner reinforcement cord layer provided inside the outer reinforcement cord layer in the radial direction of the tire; and a shear rubber layer provided between the outer reinforcement cord layer and the inner reinforcement cord layer. The outer reinforcement cord layer includes: a first cord layer having first cords arranged tilted relative to the circumferential direction of the tire; and a second cord layer provided outside the first cord layer in the radial direction of the tire and having second cords arranged tilted relative to the circumferential direction of the tire in the direction opposite the direction in which the first cords are tilted. The inner reinforcement cord layer includes a third cord layer having third cords arranged parallel to the circumferential direction or the axial direction of the tire.

    Abstract: An airless tire includes a tread ring including an elastic body and having a cylindrical form and a ground contact surface, a hub including a substantially non-extensible material and positioned on a tire radial direction inner side of the tread ring such that the hub is fixed to an axle, and multiple spokes including an elastic material and connecting the tread ring and the hub. Each of the spokes has an outer edge fixed to the tread ring and an inner edge fixed to the hub such that the outer edge and the inner edge are extending obliquely with respect to a tire axial direction, and the spokes are formed such that the outer edge of each of the spokes has compression rigidity Sr which is greater than compression rigidity Sh of the inner edge of each of the spokes.
