摘要： A detachable body includes an opening portion, an opening and closing member, a sealing member, a sealing member, and a protrusion portion. The opening and closing member is movable between an open position and a closed position. The opening and closing member includes a facing portion that faces the opening portion with a gap when the opening and closing member is located at the closed position. When the opening and closing member is moved to the open position, the sealing member has a thickness that is thicker than a gap between the opening portion and the facing portion. When the opening and closing member is moved to the closed position, the sealing member elastically deforms to seal the opening portion. The protrusion portion protrudes from one of a frame portion around the opening portion and the facing portion toward the other.
