(Task) To provide a technique of appropriately connecting and fixing both units irrespective of environments for arrangement of a tank unit and a heat source apparatus unit. (Solving means) When a tank unit and a heat source apparatus unit are arranged in parallel to couple the first metal tool (40) and the second metal tool (70), not only a screw can be inserted from outside of the second side face plate {74(76)} in the second through hole {82(86)} and the first screw hole {52(56)} in communication with each other, but also a screw can be inserted from inside of the first side face plate {44(46)} in the first through hole {50(54)} and the second screw hole {80(84)} in communication with each other. Therefore, by working from an outside direction of the second side plate (74) of one side (which is also an inside direction of the first side plate (46) of the other side), the second side face plate (74) of one side and the first side face plate (44) of one side can be connected by screw fixing, while the first side face plate (46) of the other side and the second side face plate (76) of the other side can be connected by screw fixing. |
