PROBLEM TO BE SOLVED: To prevent the drop of the occlusion performance of hydrogen occluding alloy, by facilitating the handling of the hydrogen occluding alloy. SOLUTION: This absorptive freezer is provided with a plurality of hydrogen occluding alloy 83 in the shape of short rings, within a hydrogen occluding storage 80 provided on the main tank of a noncondensing gas storage to store noncondensing gas, and a ceramic heater 84 is inserted into the insertion hole of the center member at its center. When the ceramic heater 84 is supplied with a current, heat is conducted to it from inside the hydrogen occluding alloy 83, and the temperature goes up, and the oxide film at the surface is broken, and it is activated. Moreover, since the water does not condense, the moisture does not adhere to the surface, and it does not produce a water screen, so the occlusion performance of hydrogen gas is secured. Since a ceramic heater 84 is arranged at the center of the hydrogen storage 80, the heat conductivity to the hydrogen occluding alloy 84 is good, and it can suppress the power consumption. The quantity of heat insulating material provided outside the hydrogen storage 80 gets off small. The quantity of occlusion can be adjusted by the number of pieces of hydrogen occluding alloy 83.
