Abstract

PURPOSE: To make it possible to stably and surely hold an automatic pencil axis on the predetermined protruded and sunk positions by a method wherein at the position where one of the first and second refills is sunk and the other is protruded, a turning stop boss with which a cam coupling boss is coupled on the other side section is formed on a stopper step section which is located on the rear end side of an automatic pencil cap. CONSTITUTION: After an automatic pencil axis 4 and eraser axis 5 are sunk and housed in a front outer cylinder 1 and a rear outer cylinder 3 is turned around, a cam surface 61 of a slider 6 on the automatic pencil axis 4 side is pressed and slid by a cam coupling boss 30, the slider 6 being advanced. Then, the automatic pencil axis 4 is advanced and protruded through the front outer cylinder 1. In this protruded position, the cam coupling boss 30 has a contact with a side of a turning stop boss 25 on a rear stopper step section 24 and one side rotation of the rear outer cylinder 3 is restricted. Thereafter, an inner coupling boss section 31 responsive to a notch section 26 is in a position to knock the rear end of the rear outer cylinder 3 wherein the automatic pencil axis 4 is maintained in a writing position after the cam coupling boss 30 has been coupled with the rear end clamping section 61a of the cam surface 61.
