An infant incubator including: a bed of an infant a first supporting-shaft disposed at obliquely above the bed, extends substantially horizontally, and rotatable back and forth at a predetermined extent around an axis a rotation stay fixed to and rotated with the first supporting-shaft a second supporting-shaft provided with the rotation stay and parallel to the first supporting-shaft and a heater disposed at obliquely above the bed, supported to the rotation stay rotatably back and forth at a predetermined extent around the second supporting-shaft, and possible to emit heat ray obliquely to an upper surface of the bed, wherein a position of the heater can be varied between a heating position for emitting the heat ray and a folding position for moving away from above the bed and at the heating position, an emission angle of the heat ray from the heater is further varied.
