Abstract

Abstract PURPOSE:To improve the precision by arranging parts of a boss and a ring in a mold to mold a boss plate and spokes and inserting nonferrous metal to mold the boss and the ring inclusively for molding the boss plate and spokes. CONSTITUTION:A metallic boss 11 and a ring 10 of a metallic tube are respectively arranged at fixed positions in a mold to shape spokes 13, 14 and a boss plate 12 in one body. Then, moldable nonferrous metal such as aluminium and the like is injected into the mold. By this molding, a boss plate 12 molded inclusively with the boss 11 in the center and horizontally symmetrical spokes 13 and 14 with the boss plate 12 connected on one end and the ring 10 exclusively molded on another end are shaped. Meanwhile, the boss plate 12, spokes 13 and 14 are taken out from the mold for trimming in the secondary process. The whole body of a handle frame thus shaped is covered with a resin cover 20 for constructing a handle.
