Abstract
In order to improve efficiency of core rubbing operation and also to facilitate reduction in thickness of a coil device, a core-combining member includes substantially U-shaped topside and backside cover members, and a pair of core members are clamped and combined together from top and backsides by fitting the topside and backside cover members to each other. Legs of the topside cover member are provided with leg-openings formed therein while legs of the backside cover member are provided with convex parts for retaining to edges of the leg-openings so as to prevent detachment. A play clearance in the front and rear direction is provided between the convex part and an edge of the leg opening. Core rubbing is performed by relatively moving the cover members in the front and rear direction so as to integrally move the core members while maintaining the core members to be clamped. Stopper means is provided for restricting the relative displacement in the front and rear direction.
