DETAILED DESCRIPTION OF THE INVENTION (Industrial field of application) The present invention relates to a synthetic resin binding device, more specifically, a substrate having an upright portion that stands up on one side in the width direction, and is supported so as to be tiltable with respect to the substrate. A presser having an oscillating plate biased in a tilting direction by a first spring, a cylindrical first binding rod mounted upright on the oscillating plate, and a second binding rod insertable into the first binding rod. It is tiltably supported with respect to the body and the substrate, has an engaging portion that engages with the pressing body, and is biased in the upright direction by a second spring to lock the swinging movement of the pressing body in the tilting direction. The present invention relates to a binding tool made of synthetic resin including a lock body.

(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 incinerated 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 the binding are made of incinerable synthetic resin,
By making the binding device incinerable, it has been proposed to incinerate the entire binding device with the paper pieces still bound.

(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 strength is generally higher than that in the case where the binding device is formed of a metal member. In particular, the strength of the protruding 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.

Therefore, for example, when a file with the binding device attached to the spine is accidentally dropped, the impact load due to the piece of paper bound in the binding rod acts on the first and second binding rods, and at the same time, each of the binding rods The concentrated load is concentrated on the base end portion, and the concentrated load acts on the base end portion as a shear load. As a result, in the first binding rod, there is a problem that the hollow base end portion is damaged, and further, when the file is dropped, when the binding tool drops in a state where it is vertical to the floor surface, The impact load due to the paper piece bound in each of the binding rods is applied to the first and second binding rods, and acts on the first binding rod as a bending load in the length direction of the substrate.
The pressing body moves relative to the substrate in the lengthwise direction, and by this relative movement, the engagement between the engaging portion of the lock body and the pressing body is inadvertently released. The rocking plate is tilted with respect to the substrate by the first spring,
There is a problem that the second binding rod is disengaged from the first binding rod by the momentum and the paper pieces bound in the first binding rod are scattered.

The present invention has been devised in view of the above problems, and the purpose 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.
