PROBLEM TO BE SOLVED: To stably supply exhaust air means for an air exhauster with the highest effect by applying proper cutting work to an object to be cut. ! SOLUTION: A degassing device in an injection molding device, rapidly exhausting gas in a runner and a cavity to outside a machine is obtained by: installing a dent with about 4 mm width and about 2 mm depth on a head of an ejection pin or plug with about 12-16 mm diameter or part of a metal mold, with a standard that a cutting angle is 45 degrees and a ratio of a cutting part is width 2 : depth 1, for exhaust air means of the injection molding device decompressing compressed gas by passing through an extremely narrow passage, and guiding gas in a subsequent machine to the outside the machine by the decompression effect; conducting an opening with a width and height of about 0.2 mm into an exhaust air path from part of the dent; and installing a large number of combinations of the dent and the opening. !
