Abstract
A cooling passage is formed to have a helical configuration so that a flow rate of a cooling medium supplied to the cooling passage is controlled to be in an optimum cooling region. Accordingly, the contact surface area and the cooling volume of cooling water are decreased respectively. Further, it is possible to stably obtain an optimum casting quality with ease.
