A window shade adjustment device includes a top rail having two covers on two ends thereof, a housing located between the two covers and having a scrolling part located there. A shade is connected to the top rail and lifted or lowered along with rotation of the housing. Two end caps are respectively engaged with the two ends of the housing. Each end cap includes a tubular portion and a flange which extends radially therefrom. The flanges each are a ring-shaped part, and the thick of the flange is reduced from a center of the flange toward the periphery of the flange so as to form a ramp face that faces the housing. Multiple protrusions protrude axially from the ramp face of each of the flanges. When the shade moves upward and tilt, the shade moves along the ramp face and the protrusions which guide the shade not to tilt.
