In other words, it is the construction improvement of the pencil eraser that especially without the parts for fixing, after the top of the pencil is made to form a circle and the inner side of the eraser is also mado to, and then the two parts is attached each other by bond so that the condition of the fixing a eraser is strong and the eraser can be used to an end.

Background Art.

Althongh the previous pencil erasers are made to fix erasers by dint of fixing girdle, those are likely to be out of the top of pencil, and is cut at the edge by girdle.

And there is another type of fixing eraser.

Brief Description of Drawings The first thing is a partial - separation Drawing of this invention. The Second is a chief-length Drawing of this invention. The construction and the effect of operation of this can be explained as follows ; As we know from the firse .and second drawing, the top(2) of pencil(1) should be made slenderly than the pencil(l) and the oval- cutting part ^{ 2 - ) is attached to the oval holeO ¹ ) made at inner side of erarerO) with the bond (4).

Best Mode for Carrying out the Invention This invention make the top of pencil slenderer than the pencil and the oval-cutting part of pencil is attached to the that of inner side of. eraser by using bond. There fore the direction of erasing has no limits, so it is useful.

Industrial Applicability This invention is composed of the form of that the eraser is attached to the pencil ^• firmly.

And when we use the eraser, we can sustain the balance of power so that it is easy to do operation.

And if we use the eraser for a long time, the type of eraser is worn out as form as a oval and then the eraser is still on the top of pencil to an end.

In the result of such a fact, the eraser can be used to an end without extravagance and will be convenient to use.
