Abstract
(EN)

PROBLEM TO BE SOLVED: To provide an air blower capable of improving reliability in operation by restricting a pressure difference generated between an upper surface and a lower surface of an air blower.

SOLUTION: An air blower 10 of this preferred embodiment comprises; a housing 11 including an inlet port 17a for taking external air, a storing chamber LR communicated with the inlet port and a discharging port 17b for discharging air in the storing chamber to an external part, a motor 12 arranged in the storing chamber of the housing and provided with a coil, and a fan 13 arranged at a rotating shaft of the motor to take external air into the storing chamber from the inlet port and to blow air from the storing chamber into the discharging port. The fan 13 comprises; several plate-like blades 131 arranged on the first surface 13a radially from a rotation center CO toward the peripheral part and several grooves 133 arranged on the second surface 13b opposing against the first surface and at a position opposing between several adjoining blades toward the peripheral part.
