SILENCING VENTILATING STRUCTURE
To provide a silencing ventilating structure that can restrain entry of water into a silencer without impairing ventilating performance, and can restrain generation of wind noise.SOLUTION: In a silencing ventilating structure, a silencer is arranged in a pipe-like member installed so as to penetrate a wall. The silencer comprises a fitting part inserted into the pipe-like member from one opening part of the pipe-like member, a ventilating part penetrating in an axial direction of the pipe-like member, and a silencing part arranged in an outer peripheral part of the ventilating part. The silencing part comprises a hollow part, and an opening part allowing communication between the hollow part and the ventilating part. In at least a portion of the fitting part, an inside surface of the fitting part is inclined toward the side of the pipe-like member as going toward the side of a tip of the fitting part.SELECTED DRAWING: Figure 1
【課題】換気性能を損なわずに消音器内への水の浸入を抑制でき、風切り音の発生を抑制できる消音換気構造を提供することを課題とする。【解決手段】壁を貫通して設置された管状部材に、消音器が配置された消音換気構造であって、消音器は、管状部材の一方の開口部から管状部材内に挿入される取付部と、管状部材の軸方向に貫通する通気部と、通気部の外周部に配置される消音部と、を有し、消音部は、空洞部、および、空洞部と通気部とを連通する開口部、を有し、取付部の少なくとも一部は、取付部の内側の面が、取付部の先端側に向かうにしたがって管状部材側に傾斜している。【選択図】図１
