To easily find a fixing state and prevent the coming off of an electric wire, even if bending force is applied.

A bowl-shaped cover main body 10 for covering a terminal metal fixture T is made of hard resin, and a locking piece 12 to be locked to a receiving part R on an appliance K side is formed in the cover main body 10. An electric wire cover 20 covering an electric wire W is connected, capable of relatively displacing to the cover main body 10 by the pivoting structure of a supporting shaft (a connecting means) and a bearing hole (a connecting means). Since the locking piece 12 is made of hard resin, engaging sense of click with the receiving part R is large, and the fixing state of a terminal cover A can be understood correctly. When the upward bending force is applied to the electric wire W in the fixed state, the electric wire cover 20 is relatively displaced upward, the bending of the electric wire W is allowed, the engaging part of the locking piece 12 and the receiving part R is not affected by the bending force, and the terminal cover A will not come off.
