<;P>;PROBLEM TO BE SOLVED: To provide a structure not to be easily detached even when an animal moves a little. <;P>;SOLUTION: A metal in a long length shape is bent into a U shape, has a first clamp piece 10 on one distal end side and has a second clamp piece 20 on the other distal end side, and the clamp pieces 10 and 20 cooperate to clamp the body hair of the animal. The distal end 22 of the second clamp piece 20 is bent so as to be convex to comb teeth 15, and a space part 23 is formed between the second clamp piece 20 and the comb teeth 15. The longitudinal direction of the space part 23 and the longitudinal direction of the comb teeth 15 are made to cross roughly perpendicularly. <;P>;COPYRIGHT: (C)2008,JPO&INPIT
