PROBLEM TO BE SOLVED: To reduce a cost by a method wherein an elastic body, capable of being replaced with a foamed molded body, is molded integrally with a main body, then, a foamed body, having elastic property, flexibility, shock-absorbing property and toughness at the same time and manufactured through a different process, is inserted. SOLUTION: This different materials injection molding method is provided with a process for connecting a primary molded body to a secondary molded body and a first soft resin material is different from a first different material main body 2a but is a soft material while a second soft resin material is different from a second different material main body 2b and is a soft material. In the afore-mentioned process, one surface side of the primary different material main body 2a is connected to one surface side of the second different material body 2b to form a final main body 2, then, a first projected body 3a and a second projected body 3b are positioned on the front and rear surface sides of the final main body 2 to form a final projected body 3 while a first recess 19a and a second recess 19b are formed in the final projected body 3 to form a cavity. |
