Abstract: A solar power generator overlies a solar power generator when stowed. A plurality of solar cells of the solar power generator includes first solar cells each having a corner at one end of one side, and second solar cells disposed adjacent to the first solar cells. Each of the second solar cells has a chamfered part at an end, corresponding to the one end, of a side facing the one side. When viewed along thickness direction D3 of a support, a cushioning part of the solar power generator is disposed between the corner of the first solar cell and the chamfered part of the second solar cell and projects more outwardly along the thickness direction D3 of the support than the plurality of solar cells.

Abstract: A cooling device is made compact without impairing the desired cooling efficiency. A secondary cooling device (70) has a heat exchanging part (46) for condensing a vaporized coolant flowing in a condensation path (47) into a liquid coolant, and an evaporator (EP) arranged under the heat exchanging part (46) to vaporize the liquid coolant flowing in an evaporation pipe (52) into the vaporized coolant. The secondary cooling device (70) has a plurality of natural circulation circuits (72) independent of one another. In each natural circulation circuit (72), the liquid coolant flows down from the condensation path (47) of the heat exchanging part (46) to the evaporation pipe (52) of the evaporator (EP) through a liquid piping (48), and the vaporized coolant flows from the evaporation pipe (52) of the evaporator (EP) to the condensation path (47) of the heat exchanging part (46) through a gas piping (50).
