PROBLEM TO BE SOLVED: To provide a catch basin which can be stably installed without any wobbling even in a narrow embedding space and has such excellent workability that the connection angle of a pipe joint is understood at a glance.SOLUTION: A catch basin CB includes: a basin body 1; and a pipe joint 2 rotatably attached to the basin body 1. A flange-like body 3 is installed in the pipe joint 2 and/or the basin body 1. The flange-like body 3 is positioned on a surface perpendicular to the rotational axis A1 of the pipe joint 2. The flange-like body 3 installed in the pipe joint 2 and/or the basin body 1 plays a role of another support part of the catch basin CB so as to enable the catch basin CB to be stably installed, and also plays a role of rotation angle reference to enable how much the pipe joint 2 is rotated to be understood at a glance. |
