Claims

[Scope of utility model registration request]

In a spacing plate inserted to adjust the distance between two members connected via a connecting pin, one side of the outer periphery is a roughly semicircular curved part, and the other side is approximately the axis of the connecting pin. It has two spacing plate bodies that are straight parts that pass through,
A semicircular pin hole is formed in each of the spacing plate bodies at approximately the center of the straight portion, and an engaging protrusion is formed on one side of both ends where the curved portion and the straight portion of each spacing plate body intersect. and a locking protrusion that can be bent toward the retaining protrusion is formed on the other side, and each of the spacing plate main bodies is arranged such that the engaging protrusion and the locking protrusion face each other. After being inserted between the members, the locking protrusions on one of the spacing plate bodies are bent toward the engaging protrusions on the other spacing plate body, thereby holding the respective spacing plate bodies together. Features a spacing plate.
