Provided is a sterilizing apparatus for retorted products, which can transferthe retorted products unidirectionally to and from a retort and which can heatand sterilize the retorted products homogeneously for a short time, while slidinga carriage carrying the retorted products reciprocally in the retort. The rotatingmotions of a rotating drive source (16) disposed on the outside portion of theretort (3) are transmitted through a shaft sealing mechanism (13) to a cam mechanismin the retort, and are converted into reciprocal motions by the cam mechanismand transmitted to the carriage (7) carrying the retorted products (4), so thatthe retorted products can be heated and sterilized while the carriage (7) beingslid forward and backward or rightward and leftward of the retort.
