PURPOSE:To improve the work efficiency by arranging a grip skin material having a prescribed form like a bag in a prescribed position in a grip forming mold and injecting a resin or the like into this mold to form a grip core material in the grip surface material as one body. CONSTITUTION:A cylindrical grip skin material 34 is preliminarily seamed by a machine. This material 34 has the margin to seam put on the inside and is arranged in a prescribed position in a grip forming mold 40. A hot runner mold 44 is moved left, and it is stopped when a front end part 46a of a core 46 supported and fixed in the hot runner mold 44 is stored in a recessed part 42c of divided molds 42a and 42b. The material 34 is clipped between divided molds 42a and 42b and the mold 44 through resin supply paths 44a and 44b of the hot runner mold 44. The fused resin is injected into molds 42a and 42b to form a grip core member 32. Thereafter, molds 42a and 42b are separated from each other and the mold 44 is drawn back, and a formed grip part 30 is separated from the core 46 to form the grip part 30 along the axis. |
