Abstract

PURPOSE:To hold magnetic cores at a specific track interval by pressing core holding parts with the internal wall of a case and pressing the magnetic cores against a reference surface when a core support is fitted in the case. CONSTITUTION:When the core support 8 having the core holding parts 8b and 8b is fitted in the case 6, the magnetic cores 1 and 2 are pressed against the reference surface of the core support with the holding parts 8b and 8b. Therefore, when the support 8 is fitted in the case 6, the cores 1 and 2 are held at the specific track interval simultaneously.

Effects As explained below, according to the present invention, when the core support is fitted into the case, the core holding portion of the core support 1 is pressed by the inner wall of the shield case, and the magnetic core is held in the core support.
Since it is pressed against the reference surface of 1, the magnetic core can be held at the same time when the case and core support 1 are mated, making it unnecessary to glue the magnetic core and core support 1. Furthermore, since the magnetic core is mechanically pressed against the core support 1, the magnetic core has the advantage that the degree of fixation does not change easily even in response to changes in the external environment.
