<p><P>PROBLEM TO BE SOLVED: To provide a washing wire device which hardly causes damages on the bend part of a drainpipe by frictions when being applied to the bend part. <P>SOLUTION: The washing wire device is used for washing the inside of the drainpipe and is provided with a wire body deformable roughly following the bend part of the drainpipe. For the purpose of washing the inside of the drainpipe including the cast-iron bend part, the device includes: the wire body 11 which has, on the outer surface, a wire layer 12 having both rigidity to move straightly inside the drainpipe and flexibility to pass through the cast-iron bend part of the drainpipe, and where a washing liquid pipe 13 positioned at a deep part is covered with the wire layer; and a plastic helical cover body 14 having a structure deformable accompanying the deformation of the wire body, composed of a material of a small frictional coefficient against the cast-iron bend part, and covering the wire body as a means for reducing the friction of the wire layer to be slidably in contact with the cast-iron bend part of the drainpipe. <P>COPYRIGHT: (C)2010,JPO&INPIT</p> |
