ある。The outer diameter of the rivet before forming the rod is φ1 to φ1.
The outer diameter of the head portion after molding is preferably 3 to 8 mm. This is because, when the rod is smaller than φ1 mm, the peeling strength is insufficient, and when the rod is larger than φ3 mm, the rivet head after molding becomes too large and is not conspicuous in appearance.
