1. A terminal fitting comprising:
- a first terminal fitting component having a first flat plate; and
a second terminal fitting component having a second flat plate;
wherein the first and second terminal fitting components are fixed to each other on a condition that the first and second flat plates are placed one upon another,the first flat plate having a through hole, andthe second flat plate having a solid projection protecting from the second flat plate, the solid projection being inserted in the through hole,wherein an enlarged part is formed by crushing an end part of the inserted solid projection toward the second flat plate, so that the enlarged part comes in close contact with walls forming the through hole and the entire solid projection, so crushed, is contained within the through hole, so as to prevent the enlarged part from coming into contact with any other article, and the enlarged part completely fills the through hole, and the first flat plate is held between the enlarged part and the second flat plate;
wherein an inner surface of the through hole is provided with a tapered surface inclined in a direction in which the through hole is gradually enlarged in a direction away from the second flat pate placed on the first flat plate,wherein the inner surface of the through hole is further provided with a parallel surface that is located nearer to the second flat plate than the tapered surface is located, the parallel surface continuing to the tapered surface and facing with an outer peripheral surface of the solid projection before formation of the enlarged part having a distance therebetween.

Abstract
A terminal fitting includes first and second terminal fitting components. The first terminal fitting component includes a first flat plate having a through hole and caulking pieces. The caulking pieces stand up from both edges in the width direction of the first flat plate. The second terminal fitting component includes a second flat plate having a projection. The projection is inserted in the through hole, an end part of the projection is crushed, and the second flat plate is caulked with the caulking pieces so that the first and second terminal fitting components are fixed to each other, thereby obtaining the terminal fitting.
