  • Magnetic head arm, method of producing the same and apparatus for producing the same
    Patent number: 5657531
    Abstract: A mounting portion (protruding portion provided with a through hole) of a magnetic head assembly is fitted into an insertion hole formed at the forward end of a carriage arm, and a thus-produced inlay portion is disposed between adjacent first members having a V-shaped slit. A second member is pushed into the V-shaped slit of each first member and the magnetic head assembly is pressed against the carriage arm by the expanding force of the slit portions of each first member which is produced in proportion to the amount of insertion of the second member, and the magnetic head assembly is held in a fixed state. In this state, a caulking ball is press-fitted into the through hole of the protruding portion with a caulking pin so as to caulk the inlay portion. The magnetic head assembly is pressed against the carriage arm perpendicularly thereto.
