Abstract
According to one embodiment, a ramp of a magnetic disk device, includes a ramp main body and a support bracket molded to be integrated as one body from resin and a metal reinforcement plate embedded in the ramp main body and opposing the support bracket. The reinforcement plate includes an opening filled with the resin and opposing a border portion between the ramp main body and the support bracket.
Claims8
A ramp of a magnetic disk device, comprising:
- a ramp main body and a support bracket molded to be integrated as one body from resin;
- and
- a metal reinforcement plate embedded in the ramp main body and opposing the support bracket, the reinforcement plate including a pair of side edges each extending in a first direction and opposing each other;
- wherein
- the support bracket extends in a second direction intersecting the first direction,
- the reinforcement plate includes an opening filled with the resin and opposing a border portion between the ramp main body and the support bracket,
- the border portion extends in the first direction by an amount equivalent to the thickness of the support bracket, and
- in plan view, an interval between a periphery of the opening and the border portion is greater than zero and less than a thickness of the support bracket in the first direction.
