A roller includes a rim assembly and a tire assembly. The tire assembly includes a support ring and a tire mounted at the periphery of the support ring. The support ring and the rim assembly are detachably connected by a buckle structure. The buckle structure includes a plurality of elastic accommodating parts disposed on the inner side of the supporting ring, and a plurality of buckling parts disposed at the rim assembly. The elastic accommodating parts and the buckling parts are detachably connected. The elastic accommodating parts protrude out of the inner side of the support ring, and two ends of each elastic accommodating part are separately provided with a protruding first limiting block and a protruding second limiting block. The buckling parts are limited by the first limiting blocks and the second limiting blocks. The rim assembly and the tire assembly of the roller are detachably connected.
