<p>PROBLEM TO BE SOLVED: To actualize a box body for protecting electronic components which has a metallic wire hardly deteriorating owing to thermal strain even in environment wherein the ambient temperature of an internal combustion engine, etc., easily change and can precisely be assembled even when composed of plural components. SOLUTION: A press-in pin 11 is formed on the side of a housing member 7 and a press-in hole 12 into which the press-in pin 11 is inserted is formed on the side of a base member 8. In general, when the temperature varies, expansion and contraction are caused almost around the center of a component, so the press-in pin 11 and press-in hole 12 are formed nearby an aluminum wire 4 at a distance from the center of the housing member 7. Namely, the positions where the press-in pin 11 and press-in hole 12 are formed are positions where the deterioration of the aluminum wire 4 is a problem. This constitution suppress the thermal displacement between the housing member 7 and base member 8 and also suppresses variation in the interval between a circuit board 5 and a terminal member 3 to suppress the deterioration of the aluminum wire 4.</p> |
