PROBLEM TO BE SOLVED: To provide a robot hand easily handling various types of objects. SOLUTION: A movable part 2 is moved to contact an object contacting face P of the movable part 2 on the object, a slide actuator 13 is operated to press a piston 11 into a cylinder 9 for a predetermined amount, and water stored in the cylinder 9 is supplied onto the object contacting face P from a liquid supply opening 8 via a supply pipe 10. By this, a coefficient of friction of the object contacting face P is changed due to the surface tension of the water, which enables handling of various types of objects. When returning the coefficient of friction of the object contacting face P, ultrasonic vibration is generated in the object contacting face P of the movable part 2, and moisture left on the object contacting face P is atomized and evaporated by the ultrasonic vibration.
