LIGHT ALLOY RIM FOR TWO-WHEELED VEHICLE

To provide a light alloy rim for two-wheeled vehicle which has a simple shape and can be relatively easily manufactured, and of which down-sizing is achieved while assuring rigidity thereof, and in which sticking of mud to an inner diameter side surface is reduced.SOLUTION: A step part 16 having with a step d having two rounded surfaces R2, R3 is provided between a bead seat part 13 and a well part 15. An inner diameter side surface 17 of the bead seat part is so made as to be a circular arc surface R6 or a linear surface, and is inclined in an inner diameter direction toward a width direction center side thereof. A flange part 12 rises so that an angle θ2 of an outside surface 12b thereof is 0 to 10 degrees.SELECTED DRAWING: Figure 1 【課題】単純な形状で比較的容易に製造でき、かつリムの剛性を確保して、軽量化を図り、内径側面に泥土が張付くことを低減した二輪自動車用軽合金製リムを提供する。【解決手段】ビードシート部１３とウェル部１５との間に、２個のアール面Ｒ２，Ｒ３を有する落差ｄを有する段差部１６を設ける。ビードシート部の内径側面１７は、円弧面Ｒ６又は直線面とし、その全長において幅方向中央側に向って内径方向に傾斜している。フランジ部１２は、その外側面１２ｂの角度θ２が０〜１０度で立上っている。【選択図】図１
