Abstract
In a mounting structure for mounting a conductive shielding case, accommadating therein an audio magnetic head, to a chassis via of an adjusting plate, columnar protrusions formed on both side surfaces of the shielding case are engaged with groove portions formed on cut and raised pieces of the adjusting plate. With this arrangement, it is possible to fix the shielding case and the adjusting plate. Thus it is possible to fix the shielding case to the adjusting plate without using screws, and thereby be decrease the cost of parts and manufacture.

A structure for mounting a head such that a head main body with an audio head for magnetic tapes is mounted to a chassis to be adjustable in height and angle, comprising:
- a shielding case made of conductive material for accommodating said head main body in its interior;
- and
- an adjusting plate made of conductive material for supporting said shielding case with respect to the chassis to be adjustable in height and angle in an electrically conductive condition, wherein
- conductive protrusions are formed on right and left side surfaces of said shielding case,
- a pair of cut and raised pieces are formed on the adjusting plate through cutting and raising which oppose each other while leaving a clearance for pinching the shielding case between the pieces,
- groove portions for engaging with the protrusions of the shielding case are formed on the cut and raised pieces;
- wherein
- the shielding case is fixed to the adjusting plate by engaging the protrusions of the shielding case with the groove portions.
