An adjusting device of a chair includes a base frame in which an inner frame has one end thereof pivotally connected to a front end of the base frame by a first pin and the other end of the inner frame is connected to a sound pin which extends through two first slots defined in two side walls of the base frame. A bracket is pivotally mounted to a rear end of the base frame by a third pin and a fourth pin extending through two second slots respectively defined in the side walls and fixedly connected within the bracket. An urging element is connected between a top plate of the base frame and a fifth pin which is transversely connected within the bracket via two fourth slots defined in the two side walls. A transmitting device is connected between the fourth pin and the second pin which is slidably connected between two first slots respectively defined in the two side walls. The transmitting device has a third slot defined therein for a quick release device extending therethrough such that when pulling a back portion disposed to the bracket, a seat portion disposed on the base frame can be pivoted about the first pin simultaneously. |
