An adjustable wrench has a handle having a fixed jaw, a movable jaw, an adjusting worm and an adjusting device. The adjusting worm is received in an opening of the handle and engages with the movable jaw to drive the movable jaw to move along the guiding slot. The adjusting device has an axle portion received in a through hole of the adjusting worm and a wheel portion positioned beside the adjusting worm. The adjusting device is pivoted on the handle via a shaft to be turned along a rotation axle and the adjusting worm is turned along a rotation axle. The rotation axles of the adjusting device and the adjusting worm deviate from each other whereby the adjusting device is turned to move the adjusting worm toward or away from the movable jaw.
