Abstract:

Disclosed therein is a writing pen with a rotation-preventing bent tip. The writing pen includes a rotation-preventing bent tip and a tip housing which are coupled to each other in a key-locking type to prevent a rotation of the tip or the tip housing by a pressing force generated when a user writes down. The tip has a rotation-preventing protrusion , the tip housing has a rotation-preventing protrusion and a groove to which the protrusion is coupled, and a main housing has a groove to which the protrusion is coupled, so that the tip , the tip housing and the main housing are coupled to one another in the key-locking type to thereby provide a mutual interrupting action. So, even though a great force is applied to the writing pen when a user writes down, the tip is not rotated, so that the user can use it freely and comfortably without regard to a used angle of the writing pen.
