A slat angle adjustment device for a window blind includes a casing, a transmission unit, and a driving rod. The casing has a flange inside. The transmission unit has a first worm shaft and a second worm shaft. The first and second worm shafts are rotatably disposed in the casing and meshed with each other. The driving rod has a flexible wing at an outer surface thereof. When assembled, the driving rod is inserted into the casing through a bottom hole of the casing. During the insertion of the driving rod, the flexible wing is compressed by the flange. Once the flexible wing passes through the flange, the flexible wing is restored and engaged with the flange. By this way, a consumer doesn't adjust repeatedly the assembly angle of the driving rod so as to reduce assembly time and increase assembly convenience.
