Abstract
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.

Claims Analysis
Total Claims: 11
Claim 1
Independent Claim
143 words
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 the outside; and first and second connecting members that connect the spokes disposed side by side and disperse a load applied to the spokes, wherein the spoke includes a first member that protrudes from the first band toward the second band in a curved shape, and a second member that is formed so as to connect the first member to the second band and is formed in a curved shape opposite to the first member.
