(PURPOSE) To suppress the falling of a mooring chain and prevent the generation of slackening and entanglement during its falling by fitting falling resistors at the mooring chain before dropping it into water. (CONSTITUTION) An anchor main body 2 made of concrete and a mooring chain 3 are thrown into water from a working craft 1 so as to be settled at the bottom of the water. Prior to be dropped, the mooring chain 3 is provided, at fixed spaces apart, with falling resistors formed of resistance plates 4 made of metal, wood, synthetic resin or the like. The resistance plate 4 is previously selected in its size and buoyancy so that the falling speed of the mooring chain 3 is slower than that of the anchor main body 2. The mooring chain, dropped into water with resistance plates 4 fitted thereto following the anchor main body 2, is suppressed in its falling by water resistance generated by the resistance plates 4, caught by the falling force of the anchor main body 2 and reaches the bottom of the water being brought to the vertically rectilinear stretch.
