Title: Dustproof plug
Inventor: SETOGUCHI DAISUKE
IPC: F16L55/00
Filed: 2007-10-11
Abstract: <P>PROBLEM TO BE SOLVED: To provide a dustproof plug hardly changing holding power even in expansion and contraction.  <P>SOLUTION: The holding power for holding the dustproof plug 500 by a connecting part 204 of a joining member 200 is determined by three of (1) a locking margin S for locking a claw 516 in a groove 206 formed on the outer wall 204A of the connecting part 204, (2) a force F1 for pushing the tip 208 of the connecting part 204 in the inside direction in the width direction by a cylindrical part 510 and (3) a force F2 for pushing the tip 208 of the connecting part 204 in the outside direction in the width direction by an outside end 542A in the width direction of a projection 530. When the dustproof plug 500 expands, the holding power by (1) and (2) reduces, and the holding power by (3) increases. When the dustproof plug 500 contracts, the holding power by (1) and (2) increases, and the holding power by (3) reduces. Thus, even if the dustproof plug 500 expands and contracts, a change in the whole holding power of the dustproof plug 500 is restrained. That is, the holding power held by the connecting part 204 of the joint member 200 is hardly changed.  <P>COPYRIGHT: (C)2009,JPO&INPIT
