<p><P>PROBLEM TO BE SOLVED: To provide a rust preventive member capable of restraining the extension of the rust preventive member to the inner diameter direction side caused by elastic deformation of an elastic member, while preventing rust by allowing the elastic member to abut on a pipe end surface of a spigot part, by being inserted-fitted into the spigot part. <P>SOLUTION: A holding part 5b is constituted of an extension part 5c extended toward the inserting-fitting direction to the spigot part 3a and engaging with an outer peripheral surface 3c of the spigot part 3a, a holding piece part 5d extended toward the inner diameter direction side from the extension part 5c, and a projection part 5g extended toward the inserting-fitting direction to the spigot part 3a on the inner diameter side more than the extension part 5c in the holding piece part 5d. The elastic member 5a is arranged between the extension part 5c and the projection part 5g on the inserting-fitting direction side to the spigot part 3a of the holding piece part 5d, and a cutout part 5h for allowing the extension of the elastically deforming elastic member 5a is formed on the outer diameter side from an inner diameter side end part of the elastic member 5a in a side end part in the inserting-fitting direction to the spigot part 3a of the elastic member 5a. <P>COPYRIGHT: (C)2012,JPO&INPIT</p> |
