PURPOSE: A pitch adjuster is provided to accurately adjust pitches without the deformation of fastening holes and deck plates by previously adjusting the pitches as much as pre-input values. CONSTITUTION: A pitch adjuster(1) is composed of a main body(100), an upper fixing part, a lower fixing part(400), an upper pitch adjusting part, and a lower pitch adjusting part(600). The upper fixing part is arranged on the upper side of the main body and elevates to fix a deck plate. The lower fixing part opposites the upper fixing part and grips and fixes the deck plate with the upper fixing part. The upper pitch adjusting part pressurizes the upper fixing part. The lower pitch adjusting part pressurizes both lateral sides of the deck plate to adjust pitches.
