Abstract

PURPOSE:To prevent a shield plate from falling even when a sticking part between the shield plate and an elastic plate comes off, by fitting a projecting part provided at the side plane of a slider which sandwiches a magnetic core, with the aperture part of the shield plate which encloses a slider. CONSTITUTION:Aperture parts 13a are provided at a pair of sides facing oppositely of a shield plate 13 which encloses sliders, facing with projecting parts 5a and 4a provided on the side planes of sliders 4 and 5 of a magnetic head 1. By inserting the magnetic head 1 to the shield plate 13, its side is deformed elastically to the outside, and the projecting parts 5a and 4a are fitted in the aperture part 13a. Keeping such a state, the shield plate 13 is stuck and fixed on an elastic plate 9. Therefore, the shield plate is prevented from falling even when the sticking part between the shield plate and the elastic plate comes off.
