And a swinging plate that is supported on the other side in the width direction of the substrate so as to be tiltable with respect to the substrate, a cylindrical first binding rod that is vertically attached to the swinging plate, and the first binding rod. The present invention relates to a synthetic resin binding device comprising a presser body having a second binding rod that can be inserted into and a lock body that locks the presser body inside the upright portion.

(Prior Art) Conventionally, this kind of binding device has a substrate having the upright portion, a first
Each component such as the binding rod, the swing plate, the pressing body, the second binding rod, and the lock body is formed of a metal member.

By the way, in the above-described binding device, since each component of the binding device is formed of a metal member, the piece of paper bound to the binding device becomes unnecessary, and the binding of the paper piece to the binding device is unnecessary. When incinerating as it is, the metal spelling tool is not incinerated and remains bulky, therefore, when performing the incineration, it is not suitable for use to incinerate a piece of paper with a file, It was necessary to remove the paper piece from the binding device and incinerate only the paper piece.

Therefore, in Japanese Patent Application No. 62-133407, various components of a binding device were previously formed of incinerable synthetic resin, and the binding device was made incinerable so that the pieces of paper could still be bound to the binding device. He proposed to incinerate the whole in the state of.

(Problems to be solved by the invention) However, in the binding device proposed above, since each constituent member of the binding device is formed of synthetic resin, the binding device is generally more rigid than the case where the binding device is formed of a metal member. The rigidity of the first binding rod and the second binding rod is weak, and when the file with the binding device attached to the back cover is accidentally dropped, the impact load due to the paper pieces bound in these binding rods As a result, there is a problem that these binding rods are deformed or damaged, and in particular, the rigidity of the base portion of the first binding rod protruding from the outer surface of the swing plate is a problem. That is, the first binding rod has a cylindrical shape, and the second binding rod is inserted into the cylindrical hole of the first binding rod. It has a bottomed tubular shape that is closed by, and the second binding rod inserted into the first binding rod has a length shorter than the bottom portion of the tubular hole.

That is, when the second binding rod is inserted into the first binding rod, a hollow portion is formed at the base end portion of the first binding rod.

For this reason, for example, when a file with the binding device attached to the spine is accidentally dropped, the impact load due to the paper piece bound in the binding rod acts on the first and second binding rods, and at the same time, each binding rod The concentrated load is concentrated on the base end portion, and the concentrated load acts on the base end portion as a shear load. Therefore, in the first binding rod, there is a problem that the hollow base end portion is easily damaged.

The present invention has been made in view of the above problems, and an object thereof is to incinerate a file together with a piece of paper bound in a binding tool and yet to prevent the file from accidentally falling. Even if there is, it is possible to prevent the first binding rod and the second binding rod from being deformed or damaged due to the impact load at the time of dropping, and moreover, the presser body (8) is reliably locked by the lock body.
