Shock mounting structure and magnetic disk apparatus

A shock-mounting structure comprising:

• first and second shock absorbing members each of which at least partially consists of an elastic material with a vibration damping function, which has a groove at the side, and which is separately fixed to a vibration-isolated object;
• a frame including a first elastic frame part one end of which is fixed and the other end of which is free, and a second elastic frame part oen end of which is fixed and the other end of which is free and separated from the other end of said first frame by a distance equal to that between said first and second shock absorbing members;
• first and second hooks provided on said first and second frame parst respectively so that said first and second hooks can be fitted into said grooves of said first and second shock absorbing members;
• and
• a board-like member mounted to said first frame part and to said second frame part to fix said frame to said shock absorbing member with said first and second hooks being fitted respectively into said grooves of said first and second shock absorbing members.

• a third shock absorbing member at least partially consisting of an elastic material with a vibration damping function, having a groove at the side, and being fixed to said vibration-isolated object with said third shock absorbing member being separated from said first shock absorbing member by the distance equal to the length of said first frame part;
• a fourth shock absorbing member at least partially consisting of an elastic material with a vibration damping function, having a groove at the side, and being fixed to said vibration-isolated object with said fourth shock absorbing member being separated from said second shock absorbing member by the distance equal to the length of said second frame part;
• and
• third and fourth hooks provided on one ends of said first and second frame parts respectively so that said third and fourth hooks can be fitted into said groove of said third and fourth shock absorbing members.

A shock-mounting structure comprising:

• a frame including an elastic frame part;
• a vibration-isolated object;
• a plurality of shock absorbing members, each with a groove at the side, mounted on one of said frame and said vibration-isolated object;
• a like plurality of generally U-shaped hook portions carried by the other of said frame and said vibration-isolated object and aligned with said shock absorbing members with the hook portions respectively received by the grooves of the aligned shock absorbing member;
• at least one of said shock absorbing member and cooperating hook combinations interconnecting said elastic frame part to said vibration-isolated object;
• and
• a circuit board mounted on said frame to fix said frame with respect to said shock absorbing members with said hooks respectively fitted into the grooves of said shock absorbing members.
