Abstract: A body protector comprises a plastic sheet provided with numerous air cells on one of its surfaces, and plane fastening members attached at least to the opposite end edge parts, respectively, of the plastic sheet. The plastic sheet is wound around a desired part of a human body in a tubular shape, and the plane fastening members are joined together to hold the plastic sheet on the desired part of the human body. A gap is formed between the opposite end edges of the plastic sheet when the body protector is put on the desired part.

Abstract: A small animal breeding apparatus has a frame structure in which a number of breeding spaces are defined. Each breeding space is provided with a pair of parallel guide rails fixed to the opposite inner sides of the breeding space and extending from the front side to the rear side. A breeding box provided in each breeding space has on opposite outer sides protrusions which are supported on the guide rails, respectively, for guided sliding movement. A breeding cage having an upper opening is placed on the bottom floor of the breeding box. An air supply pipe and an air exhaust pipe extend forward from the rear of the frame structure. When the breeding box is pushed rearward into the breeding space in guided movement along the guide rails, the air supply and exhaust pipes are caused to extend into the breeding box through insertion holes formed in a rear wall of the breeding box.
