CONSTITUTION: An explosive bolt includes bolt units(B1,B2), a detonator unit(D), and explosive units (F1,F2) for connecting the bolt units(B1,B2) to the detonator unit(D), respectively. That is, a plurality of bolt units are simultaneously cut by means of one detonator unit(D). Each of the bolt units(B1,B2) includes a bolt body, and an explosive unit mounted on the bolt body in order to cut the bolt body. The bolt body has a body section(11), a screw section(12) formed at a lower end of the body section(11), and a mounting hole.
