ABSTRACT:
A rebounding phenomenon of an actuator assembly is to be prevented and device assembling work and maintenance work are to be carried out separately from stopper removing work. In one embodiment, a magnetic disk device includes a stopper50for restricting a turning range of an actuator assembly8having a coil support22in a magnetic disk device. In the stopper50, rubber51is cantilevered by a support rod261so as to undergo a moment of force and fulfill a shock absorbing function in order to restrict an excessive movement of the actuator assembly8to an inner or an outer side when the rubber51is abutted against a first arm22aor a second arm22bof a bifurcated shape of the coil support22, the support rod261is disposed outside a turning track of turning ends of the first and second arms22a,22bof the coil support22, and a permanent magnet52is embedded in the rubber51to attract the first and second arms22a,22b.
