Abstract
Gates (G) are uniformly arranged in a circumferential direction only in a large annular section (). The gates (G) are equal in number to a number of pockets (). The gates (G) are arranged only at sites positioned on planes (Pa) passing circumferential centers of the respective pockets (). Weld lines (W) are thus formed only in the vicinity of the planes (Pa) of a small annular section ().
