A slat support for a vertical blind includes a gear on a top end thereof. The gear includes a toothed section and a stop section. The toothed section includes a plurality of circumferentially spaced radial gear teeth. A thickness area between upper and lower faces of the stop section is at least partially located within a tooth thickness area of the radial gear teeth of the toothed section. The toothed section meshes with a gear device that can be driven upon rotation of a splined tilt rod. When rotation to the leftmost position or the rightmost position of the gear device is reached, the stop portion is too large to engage with and stopped by the gear device, preventing further movement of the gear device and the gear of the slat support. Gear skipping problem is reliably avoided.
