Summary:PROBLEM TO BE SOLVED: To provide a high rigidity, a high strength, a reduced weight, and a reduced power requirement by employing an FRP sheet having a specific value of vibration damping coefficient ratio as a component of a cage. SOLUTION: A cage 2 comprises as components; side panels 5, 6, a ceiling panel 7, a back panel 8, a floor panel 9, and a door 10. At least some of the components are made of materials including an FRP sheet. Vibration damping coefficient ratios of the components including the FRP sheet is made to be at least 0.002, or the vibration damping coefficient ratio of the entire cage 2 is made to be at least 0.005. While the higher the vibration damping coefficient ratio, the better the vibration damping property, too high a damping coefficient ratio causes a steep increase in manufacturing cost. Therefore, the abovevalues are appropriate.
