To reduce cost, and prevent a mechanism for regulating relative rotation in a tire circumferential direction of a rim and a non-pneumatic tire from being damaged.SOLUTION: A non-pneumatic tire has an inner cylinder 21, an outer cylinder 22 and a connection member 23, in which the inner cylinder is formed of a synthetic resin material; a pair of holding flange parts 15 that projects outward in a tire radial direction, continuously extends over an entire length in a tire circumferential direction, sandwiches the inner cylinder in a tire width direction and fixes the inner cylinder is formed on the outer peripheral surface of a metal rim 12; the rim is divided in the tire width direction and has a first divided body 16 and a second divided body 17 each having the holding flange parts; the rim is dived into two in the tire width direction; a size Wa in the tire width direction in the inner cylinder is greater than a distance Wr between inner surfaces 15a facing each other in the tire width direction in the pair of holding flange parts, and the inner cylinder is formed so as to be elastically deformable in the tire width direction.SELECTED DRAWING: Figure 2 【課題】コストを抑え、リムおよび非空気入りタイヤのタイヤ周方向の相対回転を規制する機構を破損しにくくする。【解決手段】内筒２１、外筒２２および連結部材２３を有するとともに、内筒は合成樹脂材料で形成され、金属製のリム１２の外周面には、タイヤ径方向の外側に向けて突出し、タイヤ周方向の全長にわたって連続して延び、内筒をタイヤ幅方向に挟み込んでリムに固定する一対の挟持フランジ部１５が形成され、リムは、タイヤ幅方向に分割され、かつ挟持フランジ部を各別に有する第１分割体１６および第２分割体１７を備え、リムは、タイヤ幅方向に２分割され、内筒におけるタイヤ幅方向の大きさＷａは、一対の挟持フランジ部におけるタイヤ幅方向で互いに対向する内面１５ａ同士の距離Ｗｒよりも大きく、内筒は、タイヤ幅方向に弾性変形可能に形成されている。【選択図】図２
