PROBLEM TO BE SOLVED: To provisionally fit each part surely by surely preventing the swing, etc., of other parts during provisional fitting without particularly needing a means for holding the other parts after molding. SOLUTION: When each rear holder 32, 33 after molding is moved relatively to a housing 31 by each movable mold 12, 15, the runner 20 of a cavity which molds the housing 31 is left to be connected with the housing 31 through a tunnel gate 20a. The position 15a of the fourth movable mold 15 which forms the cavity for molding the housing 31 is kept to be engaged with the housing 31 during molding. |
