Abstract

PURPOSE:Not to cause crack even when collected electrons having respectively a large diameter are pressed in, by providing an injection opening at a place corresponding to the center of the gasket in a mold and feeding radially molten polyethylene. CONSTITUTION:An opening for feeding polyethylene is provided at place a corresponding to the center of gasket in a mold 2 when the cap-shaped gasket 1 is molded with polyethylene, and molten polyethylene is flown in the mold 2 from the place. Polyethylene flown in the mold runs radially in the mold 2 toward the outside, and, therefore, gasket which does not form any weld line can be obtained. Accordingly, crack is not caused even when the outer diameter of an electron-collecting pin 3 is 1.3-1.4 times as large as the diameter of the central hole 4 of the gasket. Airtight and leakage proof are much increased.
