PROBLEM TO BE SOLVED: To provide a press hub for a fan into which a drive shaft can be easily inserted.SOLUTION: A press hub 10 for fan to be attached to a fan has: a circular flange part 10A integrally formed by press working; and a cylindrical boss part 10B which integrally extends to a direction orthogonal to a flange face from a center of the flange part 10A. The press hub for fan is detachably attached to a drive shaft 5 together with the fan by: the drive shaft 5 which penetrates the boss part 10B; and a fixed part 12 which is fixed to the drive shaft. A D-shaped hole part 10a is formed at a part of the boss part 10B, and a slanted guide part 10c for guiding the insertion of the drive shaft 5 is formed between the D-shaped hole part 10a and a cylindrical part 10b of the boss part 10B. The D-shaped hole part 10a and the guide part 10c are formed by deforming a part of the boss part 10B by press working.
