CONDUIT AND HOT WATER SUPPLY SYSTEM
PROBLEM TO BE SOLVED: To provide a conduit having high resistance against scratching of a machine screw.SOLUTION: A conduit 100 is a synthetic resin-based conduit having an inner surface and an outer surface, and capable of being bent so that concave parts and convex parts are alternately continued in a length direction. The conduit 100 has: an outward wall part 101 extending in the length direction with a first width; an inward wall part 103 positioned on a radial inward side of the outward wall part 101, and extending in the length direction with a second width; and a side wall part 105 connecting between the outward wall part 101 and the inward wall part 103 so that the outward wall part 101 and the inward wall part 103 are alternately continued in the length direction. An outer surface of the outward wall part 101 has a projection part 102 projecting in a radial direction, at both ends in the length direction.SELECTED DRAWING: Figure 7
【課題】本発明は、ビスによる引っ掻きに対する高い耐性を有する導管を提供する。【解決手段】本発明の導管１００は、内面及び外面を有し、長尺方向に凹部及び凸部が交互に連続して屈曲可能な合成樹脂製の導管である。導管１００は、長尺方向に第１幅で延びる外方壁部１０１と、外方壁部１０１の径方向内方に位置し、長尺方向に第２幅で延びる内方壁部１０３と、外方壁部１０１及び内方壁部１０３が長尺方向に交互に連続するように、外方壁部１０１と内方壁部１０３とを連結する側壁部１０５と、を備える。外方壁部１０１の外面は、長尺方向の両端において半径方向に突出する突出部１０２を有する。【選択図】図７
