Reference numeral 50 denotes a center portion of the ring-shaped receiving convex portion 52 which is fixed to the threaded portion 9 in an integral manner in a state where the ring-shaped receiving convex portion 52 is fixed to the screw portion 9 in a free state with respect to the wall panel 2. In particular, since the intermediate thick portion 53 is in a state of having elasticity, the vibration due to the water hammer action is absorbed by the intermediate thick portion 53 of the vibration-proof rubber 50 and transmission to the wall panel 2 side is prevented. Transmission of noise to the indoor side due to this can be significantly reduced.

A ring-shaped receiving projection for inserting a screw portion having a flange disposed outside the pipe passage is provided at the center of the ring-shaped portion, and a lock nut is screwed from the indoor side of the screw portion into the ring-shaped receiving portion. A configuration in which the convex portion is clamped in a clamped shape, and an elastic portion capable of absorbing vibration is interposed between the ring-shaped receiving convex portion clamped in the clamped shape and the outer peripheral portion attached to the mounting case. Because it was done
Even if a water hammer action acts on the screw part, even if the ring-shaped receiving convex part at the center of the vibration isolating rubber housed in the mounting case is Since the tightening portion is free from the wall panel and has an elastic portion at its outer peripheral portion, particularly at an intermediate portion, the vibration caused by the water hammer action is absorbed by the elastic portion to the wall panel side. Is prevented from being transmitted, and the transmission of noise to the indoor side due to this is significantly reduced.
