UNDERWATER IMITATION LIVING THING AND SWIMMING WATER TANK FOR UNDERWATER IMITATION LIVING THING

摘要

PROBLEM TO BE SOLVED: To provide an underwater imitation living thing and a swimming water tank device for the underwater imitation living thing for swimming the underwater imitation living thing such as a clione, a jellyfish, a sea horse while ascending/descending it.;SOLUTION: In the clione 10 as an underwater imitation living thing as shown in Fig. 2, a buoyancy body 11 is embedded in a red viscera 12 and the viscera 12 is packed by a floating body 13 having a clione shape. In the floating state, the floating body 13 is constituted such that it retains a just standing attitude and a volume of the buoyancy body 10 determines a raising speed with an own weight of the clione 10. The clione 10 and the viscera 12 are used by clamping and molding a plastic material such as a silicone rubber, an elastomer, soft vinyl chloride, nylon to a sandwich shape. As the buoyancy body 11, a foamed body such as foamed styrol grain, polypropylene grain, sponge, or a hollow body made of plastic and subjected to hollow molding, is used.;COPYRIGHT: (C)2002,JPO
