Title:
非空気圧タイヤ
Document Type and Number:
Japanese Patent JP4674253
Kind Code:
B2
Abstract:
The invention provides a non-pneumatic tire in which a fluctuation in a circumferential direction of tire rigidity is hard to be generated by a positional relationship between a spoke position and a center position of a ground surface, and a buckling of a ground portion between the spokes can be sufficiently suppressed. In a non-pneumatic tire T comprising a support structure body SS supporting a load from a vehicle, the support structure body SS includes an inner annular portion 1, an intermediate annular portion 2 concentrically provided in an outer side of the inner annular portion 1, an outer annular portion 3 concentrically provided in an outer side of the intermediate annular portion 2, a plurality of inner coupling portions 4 coupling the inner annular portion 1 and the intermediate annular portion 2, and a plurality of outer coupling portions 5 coupling the outer annular portion 3 and the intermediate annular portion 2, wherein the inner coupling portions 4 and the outer coupling portions 5 are divided in a tire width direction, are independent in a tire circumferential direction, and are provided so as to be shifted from each other in the tire circumferential direction per zones which are divided in the tire width direction.
