PROBLEM TO BE SOLVED: To provide a bushing guard of a switching device of which the number of parts is reduced and manufacturing cost is suppressed, capable of securing the protecting performance of the bushing. SOLUTION: A pair of side guard 23, an upper guard 24, and a fixing part are integrally molded and fixed to the bushing guard 21, and by the above, different from the case of separately fixing the upper guard 24 and the pair of side guard to a main body case, the number of parts is reduced, and the manufacturing cost of the switching device is suppressed because it is not necessary to separately fix a fixing member, fixing the guards 23, 24 to the main body case 12, to the upper guard 24 and to the side guard by soldering. Further, different from such a case that only the upper part or the side part is protected, as the upper part and the side part of a power source side bushing 13 and a load side bushing 14 are protected, the protecting performance of the power source side bushing 13 and a load side bushing 14 is secured.
