PURPOSE: A fan shroud structure is provided to improve air volume because a fan has a curved band shape to extend the length of blades. CONSTITUTION: A fan shroud structure(F) comprises a fan(100), a drive motor(200), and a shroud(300). The fan is fixed to the rear side of a heat exchanger, which is arranged in the front side of a vehicle engine, in order to introduce cold air to the heat exchanger. The drive motor has a drive shaft(210) for driving the fan. The shroud has a ventilator(310) in the center thereof and a motor fixing part(330) which is extended from the inner periphery to the center of the ventilator by a plurality of stators and supports the drive motor. The ventilator has a sawtooth part(311) which is arranged at a specific interval from the tip of the fan and a reduced part(312) which is formed on the rear side of the sawtooth part. |
