Abstract
Provided is a riveting device that deforms a rivet inserted into a through-hole formed in a plurality of plate-shaped members disposed in a superimposed state and secures the plurality of plate-shaped members, the riveting device including: an upper anvil that is disposed in a state in which the upper anvil faces an end surface of a head of the rivet; a lower anvil that is disposed in a state in which the lower anvil faces an end surface of a shaft portionof the rivet; and a pressurizing mechanism that generates a pressurizing force of causing a distance between the upper anvil and the lower anvil along an axial line to decrease and plastically deforms the rivet, in which the pressurizing surface of the lower anvil is formed into a flat shape that perpendicularly intersects the axial line, and a surface roughening treatment is performed on the pressurizing surface.
