A diving mask includes a mask portion and a pair of side buckles respectively extending rearwards from the left and right sides of the mask portion. A structure that permits an easy adjustment in the relative positions between the mask portion and the pair of the side buckles is adopted in the diving mask. Two coupling blocks made of flexible material are respectively defined between two lateral sides of the mask portion and the pair of the side buckles. The coupling blocks permit the pair of side buckles to move upwards/downwards or leftwards/rightwards relative to the mask portion.
