Abstract
A magnetic device is provided. The magnetic device includes a bobbin including a hollow portion extending in a longitudinal direction, coils wound around the outside of the bobbin, a core coupled to the bobbin outside the bobbin. The bobbin includes a first winding portion around which the coil is wound, a second winding portion which is disposed at one side of the first winding portion in the longitudinal direction, and around which the coil is wound, a tolerance relief part disposed between the first and second winding portions, coupling parts symmetrically disposed to each other on the outsides of the first and second winding portions, respectively. The tolerance relief part is elastically deformable in the longitudinal direction.
