Claim:
1. A sloshing impact reducing device for a cargo hold of a vessel for a liquefied natural gas (LNG) to reduce sloshing impact caused by motion of the LNG, comprising: ascent and descent guides at proper places in the cargo hold and each including a floating body having buoyancy, which is capable of allowing the floating body to rise to a surface of the LNG; and an anti-sloshing member confined to the floating body at each corner thereof, maintained on the surface of the LNG by the floating body to suppress the sloshing impact of the LNG, wherein each of the ascent and descent guides further includes, a guide rail at a corner of the cargo hold, at which adjacent sidewalls of the cargo hold join each other, the guide rail configured to guide an ascent and descent movement of the floating body, the guide rail defining an ascent and descent space in association with the sidewalls of the cargo hold, and the guide rail provided with one pair of rail surfaces in a direction of the ascent and descent movement, the one pair of rail surfaces facing each other and defining a slit in the direction of the ascent and descent movement, and a connector connecting the floating body to a corner of the anti-sloshing member, the connector configured to move along the slit of the guide rail, and wherein the floating body is configured to ascend and descend in the ascent and descent space according to a buoyant force exerted by the LNG.
