<p>PROBLEM TO BE SOLVED: To reduce noise and thrust of air injected from an air plug when an air plug is taken out from an air socket. SOLUTION: An air passage of an air plug 1 is composed of a center hole 2 which reaches the vicinity of a tip end from a rear end surface, and a plurality of holes 3 penetrated radially dispersing from a front end of the center hole 2 toward a tip end surface of the air plug 1. When the air plug 1 is taken out from an air socket, compressed air filled into a hose of the air plug 1 side and an air pressure tool is radially dispersed from the center hole 2 in the all circumferential direction through a plurality of sectoral holes 3, and thereby, it is possible to prevent the hose from jumping by exhaust thrust, and exhaust noise pressure is also reduced.</p> |
