A slider having a connecting post ( 5 ) which is not manufactured in a normal forming process such as a pressing process, can be certainly and firmly produced in a simple manufacturing process. A slider comprises a pair of wings ( 3, 4 ) are individually formed. In one wing ( 3 or 4 ), a joining protrusion ( 8 ) protrudes from a connecting post ( 5a ) and is provided with an engaging groove or plural engaging grooves ( 9 ). In the other wing ( 4 or 3 ), a joining hole ( 10 ) is bored in the other connecting post ( 5b ). Therefore, the joining protrusion ( 8 ) is interengaged with the joining hole ( 10 ). Then, a part of the material of the other wing ( 4 ) is plastic-deformed and flows into the joining grooves ( 9 ) to join the both wings ( 3, 4 ) integrally so as to provide a desired slider body ( 1 ). <IMAGE> |
