Claims

[Scope of utility model registration request]

In a magnetic head in which the front part of a head core having a wire-wound bobbin is attached to the front opening of a metal case,
forming a spring fixing convex portion on the rear end surface of the collar portion of the bobbin;
A substantially U-shaped spring having a pair of legs, a mounting part that is bent almost perpendicularly to the legs and has a mounting hole, and a press-fitting locking piece that extends from the mounting part in a direction opposite to the legs. is fitted into the mounting hole into the convex part so that its foot enters inside the bobbin, and is fixed so that the press-fitting locking piece comes into pressure contact with the surface of the bobbin perpendicular to the rear end surface of the collar part, and the bobbin is A magnetic head characterized in that a head core inserted into the magnetic head comes into pressure contact with the spring.
