<p>PROBLEM TO BE SOLVED: To provide a water-conveyance device which is improved in mountability and can be installed while holding both side parts of a water conveyance backing plate in a watertight state by supporters respectively even if the relative mounting position or posture of each supporter is different due to curvature, flexure, step and the like of a wall surface part.SOLUTION: The water-conveyance device is constituted of: a pair of supporters 2a, 2b which are fixed to wall surface parts 6a, 6b of a structure B in a watertight state, are mutually arranged at an interval, extend parallel to one another along the wall surface parts 6a, 6b respectively, and are made of a first synthetic resin; and a water conveyance backing plate 5 which is the long tabular water conveyance backing plate 5 arranged between the pair of supporters 2a, 2b to be separated from the wall surface parts 6a, 6b, whose one side part 4a in the width direction orthogonal to the longitudinal direction is supported by one supporter 2a in a watertight state while the other side part 4b in the width direction is supported by the other supporter 2b in a watertight state, and which consists of a second synthetic resin having a lower hardness than that of the first synthetic resin and the first synthetic resin.</p> |
