RAIN GUTTER CONSTITUENT MEMBER AND RAIN GUTTER
To provide a rain gutter constituting member capable of having a proper fitting force with a fitting counterpart member and suppressing the risk of water leakage with the fitting counterpart member.SOLUTION: A rain gutter constituting member such as the lower vertical joint 20 has a cylindrical part 21 connected by inserting and fitting the cylindrical member of a rain gutter. The rain gutter constituting member includes at least one rib 24 provided in a circumferential direction part of an inner wall 22 of the cylindrical part 21 so as to project inward of the cylindrical part 21. The rib 24 has a tip surface having both circumferential ends connected to the inner wall 22 of the cylindrical part 21. The cross-sectional shape orthogonal to the axial direction of the cylindrical part 21 of the rib 24 has an end edge that is an arc or a straight line larger than the radius of curvature of an axial part of the inner wall 22 of the cylindrical part 21 to which the rib 24 is connected.SELECTED DRAWING: Figure 2
【課題】嵌合相手部材との間で適度な嵌合力を持たせることができ、かつ嵌合相手部材との間での漏水のリスクを抑制できる雨樋構成部材を提供する。【解決手段】下竪継手２０等の雨樋構成部材は、雨樋の筒部材が挿入篏合して接続される筒部２１を有する。雨樋構成部材は、筒部２１の内壁２２の周方向一部において筒部２１内側に突出するように設けられた少なくとも１つのリブ２４を含む。リブ２４は、周方向両端が筒部２１の内壁２２に接続された先端面を有する。リブ２４の筒部２１軸方向に対し直交する断面形状は、筒部２１の内壁２２のうち、リブ２４が接続された軸方向一部の曲率半径よりも大きな円弧または直線である先端縁を有する。【選択図】図２
