る。2. Description of the Related Art Conventionally, there has been known a mechanical pencil in which a cap is rotated with respect to a front shaft to feed out a large-diameter eraser from a rear end, and a rear end is knocked with respect to the front shaft to feed a core. In the conventional one, a large-diameter crown is formed at the rear end of the inner cylinder having a slit, and an eraser holder having a projection on the side surface is fitted into the inner cylinder from the slit. The cap has a spiral groove in the inner hole from the rear end, and a step portion is provided in the front end inner hole. From the rear end of the cap, the inner cylinder is inserted by fitting the protrusion of the eraser holder into the spiral groove while rotating appropriately, and with the front end of the crown abutting the rear end of the cap. The protrusion of the elastic piece provided on the side of the cap may be locked to the step of the inner hole of the cap, or the ring may be press-fitted and fixed to the shaft and locked to the step. Wear it and rotate the inner cylinder against the cap to keep it from coming off. In addition, the eraser is fixed to the rear end of the eraser holder.At this time, since the eraser holder is almost located at the rear end of the spiral groove, rotate the cap with respect to the inner cylinder and put the eraser inside the cap. I need to be immersed. Therefore, there is a problem that the assembly takes too much time.
Further, there is a problem that the process becomes complicated when assembling with an automatic machine.
