In a magnetic head suspension, a piezoelectric element is disposed within a supporting part's open section so that at least a part of its distal-side end surface faces a distal-side wall surface of the supporting part's distal end section forming a distal-side gap between the distal-side end surface and the distal-side wall surface and at least a part of its proximal-side end surface faces a proximal-side wall surface of the supporting part's proximal end section forming a proximal-side gap between the proximal-side end surface and the proximal-side wall surface in a state where the piezoelectric element's upper and lower electrode layers do not face the supporting part and any rigid members that are fixed to the supporting part. The piezoelectric element is fixed to the supporting part by a distal-side insulative adhesive agent and a proximal-side insulative adhesive agent.

A female terminal fitting (10) has a box-shaped main portion (11) with an open front end. A resilient contact piece (17) is formed in the main portion (11) for resiliently contacting a mating male tab (30). A protection wall (22) extends continuously from a bottom wall (11C) before a resilient contact piece (17) while leaving a clearance for entry of the male tab (30). Catches (23) are provided at the opposite side edges of the protection wall (22) and engage with catchable portions (24) at the side edges of the front end of the main portion (11) for resisting opening forces on the main portion (11).

A motor includes a bearing holder having a substantially cylindrical shape and a surrounding member fixed to a radial outer surface of the bearing holder. The bearing holder includes a plurality of holder protrusion portions each including a radial outer surface at least partially making contact with the surrounding member and a plurality of holder recess portions positioned radially inward of the plurality of holder protrusion portions. The plurality of holder protrusion portions and the plurality of holder recess portions are alternately arranged along a circumferential direction. A central angle of a portion of an inner circumferential surface of the surrounding member remaining out of contact with each of the plurality of holder protrusion portions is equal to or larger than a central angle of a portion of an outer circumferential surface of a bearing unit.

A cover window is provided. The cover window includes: a transparent base layer which comprises a speaker opening; a first print layer which is disposed on a surface of the transparent base layer; a protective member which is disposed on the first print layer; and a mesh structure which comprises a mesh pattern and a ground part connected to the mesh pattern, wherein the mesh pattern of the mesh structure is inserted into the speaker opening, the ground part of the mesh structure is disposed outside the speaker opening, and the protective member comprises a protective film part disposed between the first print layer and the ground part.
