A non-pneumatic tire (1) is provided including an attachment body (11) attached to an axle, an outer rim body (13) configured to surround the attachment body (11) from the outside in the tire radial direction, and a connecting member (15) configured to connect the attachment body (11) and the outer rim body (13) in a displaceable manner, wherein, in the connecting member (15), a size of one end section (15a) connected to the outer rim body (13) in the tire width direction (H) is larger than a size of the other end section (15b) connected to the attachment body (11) in the tire width direction (H).

A connection structure (10) between airless tire (30) and rim (20) and fastening members (40) thereof. The connection structure (10) includes: a rim (20) having an annular rim body (21) and an annular connection groove formed on outer circumference of the rim body (21); an airless tire (30) having an annular tire body (31) coaxially fitted on the rim body (21), multiple sockets (32) radially extending from inner circumference of the tire body (31) into the tire body (31); and multiple fastening members (40). Each of the fastening members (40) has an extension section with a predetermined length. The extension section is coaxially inserted in the corresponding socket (32) with one end protruding from an opening of the socket (32) on the inner circumference of the tire body (31). The fastening member (40) further has a base section fixedly connected with one end of the extension section. The base section is engaged in the connection groove. The fastening members (40) serve to securely connect the airless tire (30) with the rim (20).
