ABSTRACT:
A adjustable spanner includes a main body formed with a fixed jaw and a slideway, an adjustment screw rotatably mounted in the main body, a movable jaw movably mounted on the main body and formed with a neck portion having a rack slidably mounted in the slideway and engaged with the adjustment screw, and two magnetic members mounted between the slideway and the movable jaw. Thus, the movable jaw is movable in the slideway smoothly by the repulsive effect between the magnetic members and the movable jaw or the main body, thereby facilitating the user operating the adjustable spanner.
