とするノック式シャープペンシル。a core case; a split chuck connected to the core case;
a fastener disposed on the outer periphery of the split chuck and movable between an open position for opening the split chuck and a closed position for closing the split chuck; a shaft coupling disposed to press the fastener in the direction of the closed position;
An insertion mechanism consisting of a spring member stretched between the shaft coupling and the core case and urging the fastener toward the closed position is inserted into the shaft cylinder, and the shaft coupling and the base are screwed together. The tip retaining part of the shaft cylinder is held between the end surface of the cap and the engagement surface of the shaft coupling,
In a knock-type mechanical pencil, in which the lead is drawn out by the distance between the stepped part in the cap and the tip surface, which the tip surface of the fastener comes into contact with when the head of the lead case is knocked, the engaging surface of the shaft joint. A locking protrusion is formed on one of the locking surface of the shaft cylinder that contacts the locking surface, and an engaged portion having a contact portion having different heights is formed on the other side. A knock-type mechanical pencil characterized in that the amount of lead extension can be made variable by switching the engagement position between the mating protrusion and the mating part and changing the interval.
