    • PURPOSE:To stably convey small animals by supporting an animal holder to each of circulating animal retainers in such a manner as to be freely oscillating, and providing the animal holder with an engagement rod which is held immobile by engagement with an engagement piece, and disengaging the rod by the action of a guide member. CONSTITUTION:In an anesthetizing device X which anesthetizes a small animal M such as pig with carbon dioxide for slaughtering, the small animal M is put in each animal retainer Y from an entrance 1 and held therein, each animal retainer Y being provided on a ropelike member 4 guided by a rotating member 5. When moving inside a gas chamber 3, each retainer Y holds an animal holder 15 in an immobile state by engagement of an L-shaped engagement piece 22 with the engagement rod of the animal holder 15 pivotally supported to the inside of each retainer Y. As each retainer Y rises to an exit 2, the engagement piece 22 makes sliding contact with a lower guide member 6 and thereby rotates clockwise and disengages, and then the engagement rod is engaged with an upper guide member 7 so that the animal holder 15 oscillates, dropping the small animal M onto a receiving table T.

    • PURPOSE:To obtain the subject device comprising a specific simple constitution, capable of preventing small animals which advanced once from returning every time the animals want to come back and of smoothly sending the small animals to a transportation passageway, having improved operation efficiency. CONSTITUTION:First, small animals A are sent from a driving passageway 12 through an entry 4 to a transportation device 3. Then, a first divided plate 8 among plural divided plates radiately supported on a central shaft 7 of circular enclosing plates 6 is revolved from the side of a sending outlet 5 to the side of the entry 4 and fixed through an engaging material 14 of the divided plate 8 and a stopper part 16 of the enclosing plate to the end of an entry of a left enclosing plate 6b. On the other hand, a second divided plate 9 is pushed by the small animal A, moved in one direction, a third divided plate 10 revolved to the sending outlet 5 is fixed to a sending outlet end of the left enclosing plate 6b and the small animal A is forcedly sent from the entry 4 through the sending outlet 5 to a sending outlet passageway 11. Further, divided plates 8-10 are made not to move in the opposite direction by ratchet teeth 13 of the enclosing plates 6.
