<P>PROBLEM TO BE SOLVED: To provide a rust-proof member capable of suppressing extension of the rust-proof member associated with elastic deformation of an elastic member to the inner radial direction side by preventing excessive fitting into a spigot part while preventing rust due to contact of the elastic member to a pipe end surface of the spigot part, by fitting it to the spigot part. <P>SOLUTION: The elastic member 5a is disposed between an extension 5c and a protrusion 5g to the fitting direction side to the spigot part 5a of a holding piece part 5d, and the holding piece part 5d is provided with a stopper 5i which stops fitting to the spigot part 3a after the elastic member 5a elastically deforms to come in close contact with the pipe end surface 3b between the extension 5c and the holding piece part 5d. <P>COPYRIGHT: (C)2012,JPO&INPIT |
