The invention relates to the field of experimental medicine, and more particularly to devices designed to conduct experiments on animals. The problem to be solved by the utility model is to provide a device for the immobilization of laboratory animals, providing the establishment of the adaptive structure for animals of various sizes, in the implementation of object is achieved technical result consisting in improvement of animal contact with the walls of the device, with the exception risk of animal bites and irradiation experimenter, reducing the time of service equipment, expanding the range of therapeutic physical factors. To achieve said technical result, according to the utility model for immobilization of laboratory animals apparatus comprising a container for accommodation of an animal, made in the form of a truncated hollow cone comprising an upper, a front, a rear panel and a base. The outer surface of the container is covered with the rigid packaging, and the inside - a cushioning foam. The upper and front panels of the container have a number of through holes manipulation. The rear panel of the container represented in the form of a flip-up lid half-oval hole in the middle. The front panel and the base, top and rear panels, the top panel and the container base are interconnected locks, for example by a screw mechanism, or the hinge spring. Container base is further provided with two supports and handle. Rigid packaging provides a structural barrier to impact and other aggressive mechanical impacts, and cushioning foam is an effective component providing cost effective protection against vibration and impact of moderate severity. Multifunctional materials provide good aesthetic properties, transparency, impermeability and insulating properties. The inclusion in the claimed device, in comparison with the prototype, a polypropylene container in the form of a truncated hollow cone improves the conditions of its operation, provides a stable contact of the ani
