DUCT-CONNECTING STRUCTURE

PROBLEM TO BE SOLVED: To provide a duct-connecting structure that grounds one or a plurality of spacers 7b in a duct connecting portion of ducts 5 and 6, without fail, each having a conductor 3 therein. SOLUTION: In the duct-connecting structure, an adjustment structure 7 is inserted into a plane junction of flanges 5a and 6a to make adjustable a distance between the flange surfaces in connecting the ducts. The adjustment structure is a piled structure, consisting of one or a plurality of conductor-made spacers and insulator-made elastic members 7a disposed so as to hold each spacer in-between. A portion of each conductor-made spacer overlapping with the elastic members has a thin-plate planar shape and at least a part of the spacer protrudes on the outer peripheral side from the elastic member to form a protruding portion 7b1. A first electrical continuity passage 10 is formed that is electrically connected between the protruding portion of the spacer and at least one of the ducts. COPYRIGHT: (C)2011,JPO&INPIT
