PURPOSE:To avoid rattling and ease fitting by forming in a side ring inside diameter portion, a slanting plane which opens to a flange side, and forming by setting a set ring which has a similar slanting plane between rim bases, in a multi-part rim for construction vehicle. CONSTITUTION:A side ring 2 is formed in a conical plane of an inside diameter DsphiD, and with a slanting angle alpha which opens toward a flange side. And it is fitted on an outside diameter Drphi of a rim base 1 through a set ring 3 which has a similar slanting angle alpha. The side ring 2 is pressed to the flange side of the rim base 1 by a side pressure produced by internal pressure of a tire, and is automatically set concentric with a shaft center of the rim base 1 by the slanting plane of the side ring 2 and the slanting plane of the set ring 3, thereby rattling can be removed and fitting is made easy. |
