の前進後退装置。The chuck actuating body 5 of the ball chuck 1 fitted into the shaft cylinder 11 is biased backward by an internal spring 10 and can be moved back and forth by a certain length. In a mechanical pencil mounted so as to be movable back and forth via the chuck spring 9 and the trochanter 2 stretched between them, the force is greater than the force required to compress the internal spring 10 and is greater than the return force of the chuck spring 9. Advancement of a ball chuck for a mechanical pencil in which a resistance portion 15 that provides a small resistance to the trochanter 2 is formed on the inclined surface 6 of the chuck actuating body 5 at the front near the trochanter 2 holding the lead. Retraction device.
