A gripper device includes a base and two gripping assemblies, each including a gripping member, a stand, and an elastic member. The gripping member includes a gripping portion and a supporting portion. The stand is movably disposed to the base and includes a connecter and a supporter. The supporting portion is pivotally connected to the supporter at a position between the gripping portion and the connecter so that the gripping member is pivotable relative to the stand. Two opposite ends of the elastic member are respectively connected to the supporting portion and the connecter. When one of the gripping portions touches an object, the gripping member pivots relative to the corresponding stand. Therefore, gripping a target may not be interrupted by interference objects around the target.
