To eliminate needs of removal work of a molding jig from an elastic foam and removal work of a wheel after the elastic foam is formed in a tire casing.SOLUTION: A wheel 10 has: a wheel body 11 including a fitting part 13 in which a side surface 15 of an outer periphery is fitted in an inner diameter hole 43 of a tire casing 41 and having an inclined surface 16 which inclines from the fitting part 13 to a center of a diameter; and a wheel lid body 31 including a closing part 34 which overlaps on the inclined surface 16. In a manufacturing method of a solid tire with a wheel, the wheel 10 is used, the fitting part 13 of the wheel body 11 is fitted in the inner diameter hole 43 of the tire casing 41, and an elastic foam material 55 is injected into the tire casing 41 from a gap 51 between the inclined surface 16 and a peripheral edge 44b of the inner diameter hole 43 of the tire casing 41. Then, the wheel lid body 31 is overlapped on the wheel body 11 to close the gap 51 with the closing part 34 and the elastic foam material 55 is foamed.SELECTED DRAWING: Figure 4
【課題】タイヤケーシング内に弾性発泡体を形成した後に、弾性発泡体の成形用治具の取外し作業及びホイールの取付作業を不要にする。【解決手段】タイヤケーシング41の内径穴43に外周の側面15が嵌まる嵌合部13を備え、嵌合部13から径の中心に向けて傾斜する斜面16を有するホイール本体11と、斜面16に重なる閉鎖部34を備えるホイール蓋体31と、を有するホイール10を用い、タイヤケーシング41の内径穴43にホイール本体11の嵌合部13を嵌め、斜面16とタイヤケーシング41の内径穴43の周縁44bとの間の隙間51から、弾性発泡体原料55をタイヤケーシング41内に注入し、ホイール本体11にホイール蓋体31を重ねて隙間51を閉鎖部34で塞ぎ、弾性発泡体原料55を発泡させる。【選択図】図4
