A waterproof protective cover including an identifying portion which is capable of identifying a predetermined position in a chamber for receiving a connection part of electric wires in an insertion direction. The identifying portion is formed outside a side wall of either upper casing member or lower casing member. By taking advantage of the identifying portion, the connection part of electric wires can be positioned at a predetermined position in a chamber defined by the upper and lower casing members. Moreover, the chamber for receiving the connection part of electric wires has no change in a capacity thereof, so that a filling amount of the sealant is not reduced; therefore, sealing performance can be improved.
