PURPOSE: A slip device is provided to prevent the corrosion between the inner face of a driving shaft and the outer face of a slave shaft and to generate the uniform sticking force by arranging balls in the slave shaft. CONSTITUTION: A moving portion(50) is recessed inside a driving shaft(40) in an axial direction. An installing portion(70) is penetrated inside a slave shaft(60) in a radial direction. An elastic member(80) is inserted inside the installing portion. Supporting balls(90) are inserted in the installing portion to closely support the moving portion by the elastic member. Thereby, the structure is simplified and the friction area and the friction force are reduced. Moreover, the sticking force between the driving shaft and the slave shaft are maintained uniformly.
