PURPOSE: To prevent the relative position of a coil bobbin to an iron core from being changed by integraly attactching the coil bobbin around the iron core and providing the bobbin with a connection terminal for external lead connection.
CONSTITUTION: A coil bobbin 2 is integraly attached arround an iron core 1, and a connection terminal 5, used for connecting a coil 3 wound around the bobbin 2 to an external lead 4, is formed at one position on the bobbin 2. The iron core is secured to an instrument base 6. In this constitution since the bobbin 2 is integrally attached to the iron core its relative position to the core does not chance. Therefore, when connecting the external lead 4 to the terminal 5 there is no position change of the terminal since it is fixed to the bobbin.
