PROBLEM TO BE SOLVED: To provide a wind pressure resistance reducing structure for a ship capable of certainly reducing wind pressure resistance to the front surface of a multilevel accommodation space when the accommodation space includes a configuration for adjusting the separation of an airflow against the accommodation space. SOLUTION: The wind pressure resistance reducing structure for a ship includes a multilevel accommodation space 10 formed on the front of a deck of a ship 1 in a stepped shape. A bow windscreen 20 is formed forward of the accommodation space. The bow windscreen 20 reduces wind pressure resistance to the front surface of the accommodation space 10. The bow windscreen 20 is formed in a position lower than the top edge of the accommodation space. In the upper portion of the front side of a middle-accommodation space 11 positioned in a middle floor of the accommodation space 10, a middle-windscreen 21 is formed for increasing the width of a separated shear layer of an airflow separated upward of the middle-accommodation space 11. More preferably, in the front surface of a top-accommodation space 12 positioned in the top floor of the accommodation space 10, a top wind pressure reducing means is formed for reducing the width of a separated shear layer of an airflow separated upward of the top-accommodation space.
