Claims

[Claims for Utility Model Registration] By inserting the writing shaft 3 into the outer cylinder 2 and operating the operating portion 4a protruding from the rear end of the outer cylinder 2, the tip 6 of the writing shaft 3 can be moved to the tip of the outer cylinder 2. In a writing instrument in which the tip 6 of the writing shaft 3 can be retracted by holding the writing shaft more protrudingly and operating the manipulation portion 4a in the opposite direction, there is a rotation of the manipulation portion 4a between the writing shaft 3 and the outer cylinder 2. A writing instrument assembled with a rotation-linear movement conversion mechanism 7 that converts motion into axial movement.
