Patent ID: 8159789

Claim:
A magnetic head suspension comprising: a supporting part having a boss portion fixed to a carriage arm by swaging, the carriage arm being connected to an actuator, a load bending part that is supported by the supporting part and generates a load for pressing a magnetic head slider toward a disk surface, a load beam part that is supported by the supporting part through the load bending part and transmits the load to the magnetic head slider, and a flexure part that is supported by the load beam part while supporting the magnetic head slider, wherein the supporting part includes a first supporting member with which the load bending part is connected, and a second supporting member that is provided separately from the first supporting member and includes the boss portion and a main body region extended radially outward from an outer periphery of the boss portion, wherein the first supporting member is provided with a mount hole that has a shape corresponding to the outer periphery of the main body region in the second supporting member and has a diameter larger than that of the main body region, wherein at least one of the inner periphery of the mount hole and the outer periphery of the main body region is integrally provided with a rib region, and wherein the first and second supporting members are connected to each other by a restoring force of the rib region that has been elastically and/or plastically deformed by the other one of the inner periphery of the mount hole and the outer periphery of the main body region with the main body region being located at least partially in the mount hole in a through-thickness direction.
