PROBLEM TO BE SOLVED: To improve the appearance of a molded product by preventing the discoloration of a resin caused by the deterioration thereof. SOLUTION: An injection molding machine has a nozzle receiver 44 equipped with a resin flow passage 44b and positioning the injection nozzle of an injection device, a cavity 41 for forming a cavity space, a nozzle 42 equipped with a resin flow passage 68 and arranged in adjacent relation to the cavity 41 and a plurality of the runner parts 64 linearly communicating with the resin flow passage 44b of the nozzle receiver 44 and the resin passage 68 of the nozzle 42. In this case, since the resistance applied to a resin at a branch point where the resin flow passage 44b of the nozzle receiver 44 is allowed to communicate with the runner parts 64 can be reduced, the stagnation of the resin at the branch point can be prevented. The temp. of the resin stagnated at the branch point does not become high and heat history can be eliminated.
