<P>PROBLEM TO BE SOLVED: To detect a risk of water infiltration in advance, by detecting a fit state between a portion to be fit and a fitting portion. <P>SOLUTION: A fit state detection structure includes: capacitance sensors 50a-50d disposed in a connector accommodation recess 45 for accommodating a connector 48; and a packing rubber 42 disposed on a connector cap 41 to fit with the connector accommodation recess 45, so as to seal a portion of fitting between the connector accommodation recess 45 and the connector cap 41, and to contact with the capacitance sensors 50a-50d. It is detected whether or not the connector accommodation recess 45 is fit with the connector cap 41, based on a comparison result between the measured value of the capacitance sensors 50a-50d to detect a contact state with the packing rubber 42 and a predetermined first criterion value. <P>COPYRIGHT: (C)2012,JPO&INPIT |
