PROBLEM TO BE SOLVED: To prevent a malfunction of the overheat preventing device caused by the variation of electric resistance at a connector part. SOLUTION: The overheat preventing device 10 is so constructed that a partition wall 23 is installed in a connector 22 and respective terminals 20 are housed separately in terminal housings 24 of left side and right side. The malfunction caused by the variation of electric resistance is prevented because the terminals 20 are hardly short-circuited even if dew concentration occurs in the connector 22.
