An automatic analyzer including a rinse mechanism is adapted so that a suction member for suctioning up rinse water is reliably inserted into a reaction cuvette. A positioning member is connected to a nozzle support jig used to install the rinse nozzle having the suction member. The positioning member is present at a lower position than that of the suction member, has a vertically movable construction, and during a downward movement of the rinse mechanism, is brought close to/inserted into the reaction cuvette earlier than the suction member. Thus, the positioning member adjusts an inserting position of the suction member appropriately if the stopping position of the reaction cuvette deviates.
