FLEXIBLE TUBE SUPPORTING DEVICE

PROBLEM TO BE SOLVED: To reduce the bending radius of a flexible tube.SOLUTION: The flexible tube supporting device includes: a support device body 6 attached to the outer periphery of a flexible tube which is inserted into the inside of a rigid pipe along an axial direction of the pipe; and a plurality of rollers 7 which are disposed between the support device body 6 and the pipe in a circumferential direction of the pipe with a gap, and which are rotatably attached to the support device body 6 in contact with the inner face of the pipe. The support device body 6 has a flexible tube supporting device 5 includes: a first body part 11 formed with a through hole 14 of the diameter larger than the outer diameter of the flexible tube; and a second body part 12 having a wedge portion 21 to be inserted into the gap between the through hole 14 and the flexible tube in the radial direction.SELECTED DRAWING: Figure 8 【課題】フレキシブル管の曲げ半径を小さくする。【解決手段】剛体の管の内部に管の軸線方向に沿うように挿入されるフレキシブル管の外周に取り付けられる支持具本体６と、支持具本体６と管との間で管の周方向に間隔をあけて設けられるとともに、支持具本体６に回転自在に取り付けられて管の内面に接触する複数のローラ７と、を有し、支持具本体６は、フレキシブル管の外径より大径の貫通孔１４が形成された第一本体部１１と、貫通孔１４とフレキシブル管との間の径方向の隙間に挿入される楔部２１を含む第二本体部１２と、を有するフレキシブル管の支持装置５を提供する。【選択図】図８
