[0003]

However, in the filing tool 1 shown in FIG. 8, the width of the insertion piece 7 is set so that the insertion piece 7 does not come off after being inserted into the insertion opening 8. Although the length is made longer, if the width of the insertion port 8 is too long, the insertion is likely to come off, and conversely, if the width of the insertion piece 7 is too long, it becomes difficult to insert, and sometimes the insertion piece 7 is bent.

Therefore, a main object of the present invention is to provide a filing tool insertion structure in which the insertion piece can be easily inserted into the insertion opening and is unlikely to come off once inserted.

[0005]

According to the present invention, an insertion port is formed in one sheet-shaped member of an opposing sheet-shaped member, and an insertion piece is formed in the other sheet-shaped member. A filing tool insertion structure in which a notch is formed in the mouth edge on the side opposite to the inserting direction, and a notch is formed in the inserting edge of the inserting piece toward the opposite side to the inserting direction. <br/>

[0006]

Since the incision is formed at the edge of the insertion opening on the side opposite to the insertion direction, the area of the insertion opening becomes large when the sheet-like member is bent in the vicinity of the incision. Also, since the notch is formed in the inserting piece toward the side opposite to the inserting direction from the inserting edge, when the inserting piece is bent near the notch, the outermost end in the width direction intersecting the inserting direction of the inserting piece is formed. The space becomes narrower.

[0007]

EFFECTS OF THE INVENTION Since a notch is formed on the edge of the insertion opening on the side opposite to the insertion direction, if the sheet-like member constituting the filing tool is bent near the notch, the insertion opening Area is large, and since the notch is formed in the insert piece from the opposite side of the insert edge from the insert edge, the sheet-shaped member that constitutes the insert piece is bent and intersects with the insert direction of the insert piece. The width of the outer end can be narrowed, and the insertion piece can be easily inserted into the insertion port. Therefore, the width of the outermost end in the width direction orthogonal to the insertion direction of the insertion piece can be made wider than the width of the insertion opening, and the insertion piece is less likely to come out once it is inserted into the insertion opening.

Further, if a tear stop portion is formed at the end opposite to the edge of the insertion port and the edge of the insertion edge of the insertion piece, the notch is further torn during use and the sheet-like member may be damaged. There is no fear.

The above-mentioned objects, other objects, features and advantages of the present invention will become more apparent from the following detailed description of the embodiments with reference to the drawings.
