A fastener for insertion into pierced openings of a tissue wound has a body formed of a generally bioabsorbable polymer defining an initial capture area internal to the body. The body includes a pair of arms, each with an inwardly projecting cleat operably joined at an elbow portion defining an internal elbow angle. The arms are operably joined to a backspan at a shoulder portion defining an internal shoulder angle. A durable tissue retention zone is defined between the cleat and the arm. The elbow portion and the internal elbow angle define an insertion width greater than a width of the pierced openings resulting in the pierced openings stretching over the cleat and being elastically retained within the durable tissue retention zone. The fastener initially captures wound tissue in the initial capture area and then dynamically reforms in response to lateral stresses applied by the wound tissue without a fracture failure of the fastener until a minimum degradation period.

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).
