STRUCTURE FOR CONNECTING A METAL LEVER AND A METAL LINK VIA A METAL PIN

摘要

A linking structure enables a metal lever and a metal link to be linked via a metal pin. The metal lever has a circular linking hole. The metal pin has a support shaft part that can rotate in the linking hole while being insertable in the linking hole and can move a set amount in the axial direction, a head part formed at one end of the support shaft part, and a linking shaft part at the other end of the support shaft part. The metal link has a joining hole in which the support shaft part is engaged, and the metal link is linked integrally with the metal pin. At least one end part in the axial direction of the support shaft part of the metal pin is provided with a permitting part for maximizing the amount of axial oscillation of the metal lever relative to the metal pin.

主权项

1. A structure for connecting a metal lever and a metal link via a metal pin, said structure comprising:
a metal lever having a circular connecting hole; a metal pin comprising a support shaft portion, a head portion and a connecting shaft portion; and a metal link having a coupling hole and being integrally connected to said metal pin, said coupling hole being fitted to said connecting shaft portion; wherein said support shaft portion is insertable through said connecting hole, and is pivotabie and movable in an axial direction of said metal pin by a preset amount with respect to said connecting hole, said head portion is formed at one end portion of said support shaft portion and has a diameter larger than a diameter of said support shaft portion, said connecting shaft portion is formed at the other end portion of said support shaft portion and has a diameter smaller than said diameter of said support shaft portion, and said metal pin comprises an allowable portion formed on at least one axial end portion of said support shaft portion of said metal pin, and said allowable portion is configured to increase an amount of swing of said metal lever on said metal pin in said axial direction of said metal pin.
