Abstract: Fingers for holding a target project from shift members, and shift in accordance with the movement of the shift members shifted in predetermined axial directions by a shift mechanism to hold the target. Sliding members for shifting the shift members in the predetermined axial directions project from the shift members, and guide the shift members by sliding. According to this structure, a robot hand becomes smaller in size by decreasing the clearances between the fingers (moving the shift members closer to each other). Thus, the robot hand can hold a small target object within a small work space even though the robot hand conducts a parallel shift of the fingers.
