Abstract
The present rivet invention has a main body comprising a first end and a second end opposite to the first end, wherein the main body further comprises a lateral wall disposed at the second end and circumferentially extending around the main body; and a core part disposed at the second end of the main body and contained inside the lateral wall of the main body, wherein the core part has an end surface for pressing against at least an end surface of one of the work pieces when the rivet is being operated to rivet the work pieces, to allow materials of the work pieces flow outwardly of the core part. An accommodation space is formed between the core part and the lateral wall to receive materials of the work pieces flowing into the space and deform outwardly at least a portion of the lateral wall of the main body.
