The male mold 41 and the female molds 51, 52 are arranged at equal radius positions at an equal interval with respect to the center point 38a of the mating surface of the mold 38. The male mold 42 and the female molds 53, 54 are also arranged in the same way. The male molds 41, 42 are engaged with the female molds 53, 51 and a resin is injected to mold spilt elements 61, 62 and these elements are abutted.
