摘要： A microactuator mounting section is disposed between a base section and a load beam. A microactuator element formed of a piezoelectric element is contained in an element accommodation portion in a plate portion. The plate portion has a stationary part secured to the base section and a movable part secured to the load beam. The stationary part and the movable part are connected to each other by a pair of arm portions. Each arm portion comprises a first extending portion and a second extending portion. The first extending portion extends longitudinally relative to the load beam from a front end of the stationary part toward the movable part. The second extending portion extends transversely inward relative to the plate portion from the first extending portion so as to be continuous with the movable part.
