Abstract
This manufacturing method for a link part is a method of manufacturing a link part having one end portion having a connecting hole and provided on one side in one direction from an intermediate part which is long in the one direction and has a first side wall and a second side wall each having a pilot hole at least at one end portion and disposed to face each other and a connecting wall connecting one side edge of the first side wall and one side edge of the second side wall, and the other end portion provided on the other side therefrom in the one direction. The method includes a reinforcing process of inserting a metal core into the pilot hole, and an O-bending process of O-bending the first side wall and the second side wall so that the other side edge of the first side wall and the other side edge of the second side wall are brought into contact with each other after the reinforcing process.
