To provide a silencer tube that can reduce weight and cost with a simple structure and can suppress the generation of sound.SOLUTION: A silencer tube used in a vehicle sunshade device and disposed between a winding shaft and a coil spring 90 includes an inner pipe portion 101 and an outer pipe portion 102 disposed outside the inner pipe portion 101 which form a double pipe structure, the inner pipe portion 101 being formed of a member that is elastically deformable and has slidability and wear resistance, the outer pipe portion 102 being formed of a member that is more easily elastically deformed than the inner pipe portion 101, the outer pipe portion being provided with a fin 103 projecting outward along the axial direction of the silencer tube 100.SELECTED DRAWING: Figure 4
【課題】簡易な構造で軽量化とコスト削減が図れるとともに、音発生を抑制することができるサイレンサーチューブを提供する。【解決手段】車両用日除け装置に用いられ、巻取シャフトとコイルばね９０との間に配置されるサイレンサーチューブであって、内管部１０１と、内管部１０１の外側に配設される外管部１０２と、を備えて二重管構造に形成され、内管部１０１は、弾性変形可能で、摺動性及び耐摩耗性を有した部材で形成され、外管部１０２は、内管部１０１よりも弾性変形しやすい部材で形成され、サイレンサーチューブ１００の軸線方向に沿って、外側に突出するフィン１０３が配設されている。【選択図】図４
