An agitator which includes a rotary shaft fixedly provided at a free end thereof with a stirring rotor and an electric motor disposed in the vicinity of a head portion of the rotary shaft. A portion of the rotary shaft extending within the casing of the electric motor is extended through a hollow shaft, and the rotary shaft and the hollow shaft are journaled in bearings at upper and lower ends of the casing. The rotor of the electric motor is fixed to a middle portion of the hollow shaft, and the rotary shaft and the hollow shaft are interlocked with each other by a gear reduction mechanism. The agitator has a compact construction, facilitates maintenance work, and demonstrates excellent performance in agitating materials in a deep agitation tank or in agitating a liquid having a high viscosity.
