Abstract

A pair of insertion portions each having a through hole through which a lashing belt is inserted and extends are arranged at a predetermined distance from each other, and coupled to each other with coupling portions. A tension detecting portion is provided at the coupling portions. The tension detecting portion extends, at a predetermined vertical distance from a line connecting the through holes of the pair of insertion portions to each other, in a width direction of the lashing belt. In a state where the lashing belt is inserted to extend through the pair of insertion portions, a surface of the lashing belt is brought into contact with the tension detecting portion, and the tension detecting portion is configured to be broken when a predetermined or greater tension is applied to the lashing belt.

First claim

What is claimed is:

1. A lashing tension verification tool for verifying a tension applied to a lashing band member, the lashing tension verification tool comprising:
a pair of insertion portions arranged at a predetermined distance from each other, and each having a through hole through which the lashing band member is inserted and extends;
coupling portions coupling the pair of insertion portions to each other; and
a tension detecting portion provided at the coupling portions and extending, at a predetermined vertical distance from a line connecting the through holes of the pair of insertion portions to each other, in a width direction of the lashing band member, wherein
in a state where the lashing band member is inserted to extend through the pair of insertion portions, a surface of the lashing band member is in direct contact with the tension detecting portion, and the tension detecting portion is configured to be broken when a predetermined or greater tension is applied to the lashing band member.

2. The lashing tension verification tool of claim 1 , wherein
the tension detecting portion has a weak portion such that the tension detecting portion is broken due to application of the predetermined or greater tension.

3. The lashing tension verification tool of claim 1 , wherein
the pair of insertion portions, the coupling portions, and the tension detecting portion are all made of a single integral molding of a resin material.

4. The lashing tension verification tool of claim 1 , wherein
the insertion portions and the coupling portions are made of a single integral resin molding, and
at least a breakable portion of the tension detecting portion is made of a metal member.
