PURPOSE:To eliminate the need to attach and detach a screw which stops the inflow of resin by forming a groove at the periphery of the female screw of a magnetic head core support. CONSTITUTION:The groove 15 is formed at the overall periphery of the female screw 9. When resin is injected into a case 7, the resin which is expected to flow in the female screw 9 is led into the groove 15, so resin entering the screw 9 is cut off. |
