Abstract
A molding pin () is formed in a sectional shape of being held in contact at two points (contact points are denoted by P') with an imaginary cylindrical surface (C′). As a result, an undercut of a fixation hole () is reduced or eliminated, and hence it becomes easier to process a die. Moreover, a corner portion () between a cylindrical surface () and the fixation hole () becomes obtuse, and hence the die becomes less liable to deform and break. Therefore, manufacturing cost of the die can be reduced, and hence cost reduction of the bearing device can be achieved.
