PROBLEM TO BE SOLVED: To provide a terminal cover which can be surely locked and fixed without protruding from the outline of a circuit breaker case, as a terminal cover used for a circuit breaker equipped with a terminal part having a stepped structure used incorporated mainly in a distribution board or the like. SOLUTION: A terminal cover 14 attached onto a terminal part 4 of a circuit breaker isolating phase terminals in a stepped structure with interphase and left/right barrier walls 6, 7, and 8 is formed in a box-type structure having inspection holes 14a opened thereon corresponding to respective phase terminals. Right and left sidewalls of the cover 14 striding over the upper edge of the interpahse barrier wall 6 are fitted by insertion to the insides of the right and left barrier walls 7, 8. A snap-fit engaging claw 14b formed in the sidewall of the terminal cover 14 is locked to an engaging hole 7a in the barrier wall 7. A groove part 14c formed in the center of the cover 14 is fitted to the upper edge of the interpahse barrier wall 6, and a screw seat 14d protruding from the rear edge of the cover upper part is overlapped on a recessed seat surface 2a formed on the upper surface of the circuit breaker case 2 and is tightened with a screw 15.
