1. An airless tire comprising:
- a circular first band;
a second band that surrounds the first band while being spaced apart from the first band, and has a diameter larger than the diameter of the first band;
a plurality of spokes that connect the first band to the second band, are disposed between the first and second bands, and contract or expand by a load transmitted from outside the airless tire;
wherein each spoke includes a pair of first members, a pair of second members, and a first connecting member; and
wherein adjacent spokes are connected to each other via a second connecting member extending from each spoke to an adjacent spoke to disperse a load applied to the plurality of spokes;
wherein each of the first members has a first end opposite from a second end, wherein each of the first members protrude at each respective first end from the first band toward the second band;
wherein each of the second members has a first end opposite from a second end, wherein each of the second members protrude at each respective first end from the second band toward the first band;
wherein the first connecting member has a first end opposite from a second end, wherein the first end of the first connecting member connects the second end of one of the first members to the second end of one of the second members, and wherein the second end of the first connecting member connects the second end of the other first member to the second end of the other second member;
wherein each of the first members and the second members have a curved shape, wherein one of the pairs of members curves inward with each of the members extending toward each other while the other pair of members curves outward away from each other.

Abstract
The present invention relates to an airless tire, and includes first and second bands that face each other with a distance interposed therebetween, a plurality of spokes that connect the first band to the second band and are provided at intervals, and first and second connecting members that connect the adjacent spokes. The spoke includes a first member of which one end is curved from the first band toward the second band, and a second member of which one end is curved from the second band toward the first band. The other ends of the first and second members are connected to each other, and the first and second members are curved in opposite directions.
