a foam member, which is fixed to the support part such that the foam member is aligned with the upper area of the elastic body part of the elastic member to form a sealing surface for fitting the user's face in the sealing area,
wherein the elastic body part in contact with the user's face includes at least one thin area and at least one non-thin area, and a thickness of at least a part of the thin area is 7%-60% of a thickness of the non-thin area, and a width of the support part is between 2-40 mm.
