To achieve a structure in which a wheel can be prevented from coming off from a pilot part, while suppressing increase in cost.SOLUTION: A tire wheel 1 comprises a wheel main body 2 made of metal and a sleeve 3 made of synthetic resin. The wheel main body 2 has a recessed groove 12 over the whole circumference on an inner peripheral surface of a nearly toric mounting part 6, and has on a bottom surface of the recessed groove 12 an outer inclined surface part 13 inclined in a direction in which the part enlarges in inner diameter toward the outside in an axial direction. The sleeve 3 has on an outer peripheral surface an inner inclined surface part 18 which is inclined in a direction in which the part enlarges in outer diameter as going toward the outside in the axial direction and engages with the outer inclined surface part 13, and is attached to the inside of the recessed groove 12 of the wheel main body 2.SELECTED DRAWING: Figure 2
【課題】コストの増大を抑えつつ、パイロット部からのホイールの脱落を防止することができる構造を実現する。【解決手段】タイヤホイール1は、金属製のホイール本体2と、合成樹脂製のスリーブ3とを備える。ホイール本体2は、略円環状の取付部6の内周面に、凹溝12を全周にわたって有し、かつ、凹溝12の底面に、軸方向外側に向かうほど内径が大きくなる方向に傾斜した外側傾斜面部13を有する。スリーブ3は、外周面に、軸方向外側に向かうほど外径が大きくなる方向に傾斜し、かつ、外側傾斜面部13と係合する内側傾斜面部18を有し、ホイール本体2の凹溝12の内側に装着される。【選択図】図2
