ル。 Inner stage 1B of base 1 and outer stage 2B of tip chuck 6
The head 2A of the tip chuck 2 is brought into contact with the tip 1A of the cap 1 by tensioning the tip chuck spring 3 between the tip chuck 2 and the tip chuck 2, which is closed to hold the core 4 and connected to the cap 1. Inner stage 6 of shaft cylinder 6
A return spring 8 having an elastic force weaker than the tip chuck spring 3 is stretched between A and an inner cylinder 7 built in the shaft cylinder 6, and the elastic force of the return spring 8 causes the inner cylinder 7 to A fastener 9 is in contact with the chuck 2, is loosely fitted between the tip chuck 2 and the locking step 7C of the inner tube 7, and is stronger than the tip chuck spring 3 between the inner tube 7 and the core tank 11. The feeding chuck 1 is fixed to the core tank 11 by tensioning the feeding chuck spring 12 with elastic force.
A chuck-type sharp pencil at the tip, characterized in that a head 10A of 0 is closed by abutting against a fastener 9.
