PURPOSE: A stylus pen is provided to damage an I/O(Input/Output) device such as a touch screen while having a natural writing touch. CONSTITUTION: A main body(10) has a shape of a pen. A supporting groove(20) is formed by concavely cutting the inside of one end of the main body. A ball(30) is inserted into the supporting groove. A frictional part(40) is installed between the ball and an inner side of the supporting groove. The main body includes the first and the second projection part(11,12) having a distance smaller than a diameter of the ball. The first and the second projecting part prevent the ball from being separated from the main body. The frictional part is one of glass, plastics, and rubber. The supporting groove is formed in a hemispherical shape. |
