PROBLEM TO BE SOLVED: To provide a bobbin structure where rattling is prevented without adding a work process at the time of assembling. SOLUTION: A core 1 is stored in a bobbin 20 so that it is sandwiched with a base 3 constituting a core storage body 2 in a core storage 21 and a ceiling 11 constituting a cover body 10. Parts to be engaged 7a and 7b and engagement parts 15a and 15b are formed so that they are not mutually restrained and fixed. A polymerization part 31 can freely slide in accordance with the height of the core 1. Thus, the tolerance of the core 1 is absorbed and the core 1 is prevented from being exposed from the gap 30 of the bobbin 20. A creeping distance of the polymerization part 31 at the time of holding the core 1 is made to become not shorter than a distance obtained by adding the tolerance of the core 1 to an arbitrary creeping distance providing necessary insulating withstand pressure. Thus, a sufficient insulating distance considering the tolerance of the core is secured. COPYRIGHT: (C)2006,JPO&NCIPI
