This ballpoint pen is made of a material with elasticity and has an air intake hole and an air supply hole that are opened by a valve body operated by compression and decompression operations. Air is fed toward the tip and new air is replenished from the air intake hole.On the other hand, when compression is released, the volume automatically returns to its uncompressed state and both holes are closed. A supporting cylinder for supporting the air supply cylinder is formed by fitting the distal end of the air supply cylinder forming the shape into the rear end of the core, and exposing a part of the air supply cylinder from the cutouts provided on both sides. A structure characterized in that it is attached to the rear end of the shaft cylinder.
