PURPOSE: A bidirectional blower/ventilator structure is provided to facilitate intake and exhaust, since a part of a motor of an existing blower or an existing ventilator is changed. CONSTITUTION: A bidirectional blower/ventilator structure comprises a single motor(1), an intake fan, an exhaust fan, an exhaust duct(8), and an intake duct(9). The intake fan and the exhaust fan are symmetrically combined with a shaft of the motor. Air which flows in a central shaft of the fan by the drive of the motor, flows along the columnar direction of each fan. The fresh air flows toward the motor shaft along the exhaust duct and the intake duct, and indoor air flows out, simultaneously.
