<p>The invention provides a drainage pump equipped in an air conditioner having high safety by preventing water from coming into contact with a conductive output shaft of an electric motor. The drainage pump has a motor (10), rotating blades (200) coupled to an output shaft (12) of the motor (10), a case main body (50) having a pump chamber for accommodating the rotating blades (200), a lid member (30) covering an opening portion of the pump chamber (52), and a deflector board (15) provided between the lid member (30) and the motor (10). An outer peripheral groove (212) is provided in an end portion of a shaft portion (210) toward the motor (10), and the deflector board (15) is assembled by being fitted to the groove (212) in a tight contact state. Accordingly, drain water does not directly touch the conductive output shaft (12).
