A cover ( ) for preventing water from entering a junction block ( ) is rotatably held on a bracket ( ) used to mount the junction block on a vehicle body. A connector ( ) is fitted into a connector holder ( ) in an upper surface ( ) of the junction block ( ). However, a connector ( ) cannot be fitted into a connector holder ( ) provided in a side surface ( ) unless the cover ( ) is rotated counterclockwise. This enables the upper surface ( ) of the junction block ( ) to be covered for a water-entrance preventing purpose, and can prevent such an operation from being forgotten.
