PROBLEM TO BE SOLVED: To obtain a stably supported state of a catch basin body; to keep an appearance good by a skeleton mounting cover even if a gap between the catch basin body and the skeleton is widened; and to make the heat shrinkage of a downpipe absorbed by a portion where the catch basin body and the skeleton mounting cover are slidably fitted together. SOLUTION: This catch basin 4 comprises the catch basin body 5 for collecting rainwater from a drain member such as a branch pipe 2 arranged along an outer wall surface, so as to discharge the collected rainwater into the downpipe, and the skeleton mounting cover 6 which is mounted on the outer wall surface. In the skeleton mounting structure of the catch basin 4, a slide-fitting means 7 makes the catch basin body 5 fitted into the skeleton mounting cover 6 in such a manner as to be slidable only in a vertical direction H in the state of regulating movement in a longitudinal direction C; and in the state in which the catch basin body and the skeleton mounting cover are slidably fitted together, a gap between the catch basin body 5 and the outer wall surface, and the branch pipe are concealed with the skeleton mounting cover 6.
