ABSTRACT:
A high-voltage variable resistor unit including a terminal connection structure capable of preventing upward movement or rotation of the terminal by simple construction. A terminal is provided with a connecting portion between a held portion and a lead wire connected portion. A terminal fixing portion of the insulating casing is provided adjacent to a terminal holding portion with a connecting portion receiving recess in which the connecting portion of the terminal is received. An insulating resin is charged in the connecting portion receiving recess and hardened. The walls surrounding the connecting portion receiving recess have a pair of grooves each formed on a pair of walls facing to a first linear connecting portion and a second linear connecting portion of the terminal.
