CLEARANCE BLOCKING SPACER

摘要

PROBLEM TO BE SOLVED: To provide a clearance blocking spacer that enables a faucet to be connected to a faucet coupler where a faucet connection part is inserted from a wall rear part into a wall hole without using any faucet box and without any looseness of the faucet.SOLUTION: This invention relates to a clearance blocking spacer that is arranged in an annular clearance Kformed between an outer peripheral surface of an extended connection pipe Pconnected to a faucet connection part 21 of a faucet coupler Cinstalled at a wall rear part and an inner peripheral surface 33 of a wall hole Hunder a state in which the faucet connection part 21 to which a faucet V is connected is inserted from the wall rear part into the wall hole Hformed to pass through a wall material W to face against the wall front part. The clearance blocking spacer is entirely formed into a cylindrical shape with elastic material and arranged in the annular clearance Kwith the extended connection pipe Pbeing inserted and the outer peripheral part is formed with an annular protrusion (an outer diameter adjustment part) 4 in which its outer diameter varies in a taper form from an axial one end toward the other end so as to corresponding to a difference in size of the wall hole H.
