An insulator bracket of an overhead electric power line is provided to enable the damaged insulator to be easily and conveniently exchanged for another one, thereby reducing the discomfort of an operator. A crossarm body(110) includes a plurality of insertion holes(111). An insertion portion(120) is protruded from the side of the crossarm body to the outside. A fastening portion(130) is extended from the insertion portion to the outside. An insulator assembly comprises a projection(211a), receiving parts(211b,211b'), openings(211c,211c'), a rotation member body(211), supporting portions(212a,212a'), a rotation member(210) with connecting part(212b,212b') and supporting members(212,212') and insulators(220,220') including holding parts(223,223').
