<p>PROBLEM TO BE SOLVED: To provide an air blower that saves labor of finding out a molding condition regardless of a resin material or the molding condition, ensures easiness for attachment/detachment to/from the drive shaft of a fan without increasing the number of components, and suppressing occurrence of vibration and noise.SOLUTION: An air blower includes: a motor 3 that has a drive shaft 4 in its central part, and rotating the drive shaft 4; a drive transmission shaft 5 that is perpendicularly attached to the shaft direction of the drive shaft 4; a fan 2 that receives rotational force from the motor 3 through the drive transmission shaft 5 and the drive shaft 4 attached to the hole of a boss 2a provided in the central part, and rotates; and on the drive shaft or the boss 2a of the fan 2, a frictional resistance suppression mechanism that suppresses frictional resistance between the drive shaft 4 and the boss 2a of the fan 2.</p> |
