冷却していた。このため、ボルト孔の強度を高めるには
鋳造物の冷却程度を大きくすればよいが、かかる冷却方
法にあっては設備コストが高額化するとともに管理に手
間がかかるといういう不都合を有した。However, in the conventional vehicle wheel casting method, after the vehicle wheel is cast, the cast product is cooled substantially uniformly. For this reason, in order to increase the strength of the bolt hole, it is sufficient to increase the cooling degree of the casting, but such a cooling method has the disadvantages of high equipment cost and time-consuming management.
この発明の課題は、かかる不都合を解消することである
。An object of the present invention is to eliminate such inconveniences.
前記課題を達成するために、この発明の車両用ホイール
