ルチャックの前進後退装置。The chuck operating body 2 of the ball chuck is biased backward by an internal spring 6 provided in the shaft cylinder 1, and a pressing member 12 is formed with an m resistance point 5 and a protrusion 16 that cooperates with the resistance point 5. , is arranged behind the chuck body 7 of the ball chuck attached via the chuck spring 8 and the trochanter 9 stretched between the chuck actuating body 2, and presses the resistance point 5 with the protrusion 16. After the entire ball chuck advances a certain length, the protrusion 1
6 is a device for advancing and retracting a ball chuck for a mechanical pencil, characterized in that the chuck operating member 2 is capable of retracting while overcoming the resistance point 5.
