PROBLEM TO BE SOLVED: To provide a solar heat driven freezing machine capable of Increasing a yearly heat output amount than in the prior art. SOLUTION: A solar heat driven freezing machine is adapted such that there are switchably coupled first high temperature side section containers 11, 13 in which there is filled first high temperature hydrogen adsorption alloy MH1 having lower equilibrium hydrogen pressure than that of low temperature hydrogen adsorption alloy MH2, and second high temperature side reaction containers 81, 82 in which there is filled second high temperature hydrogen adsorption alloy MH3 having higher equilibrium hydrogen pressure than those of the low temperature hydrogen adsorption alloy MH2 and the first high temperature hydrogen adsorption alloy MH1, with respect to low temperature side reaction containers 12, 14 in which there is filled the low temperature hydrogen adsorption alloy MH2 having higher equilibrium hydrogen pressure. As a result, there is ensured migration of hydrogen gas between the low temperature side reaction containers 12, 14 and the one high temperature wide reaction containers 11, 13.
