PROBLEM TO BE SOLVED: To provide a connecting structure for piping members capable of easily and surely connecting piping members at high sealing performance.SOLUTION: A connecting structure for a pair of resin piping members includes: the pair of piping members having cylindrical portions capable of circulating a fluid, and flange portions arranged on outer peripheries of the cylindrical portions at one end side, in which end faces on one end sides of the flange portions come in contact with each other; a pair of circular contact members having center hole parts for inserting the cylindrical portions, contact parts come in contact with end faces on the other sides of the flanges, and diameter outward parts located in a diameter outward direction rather than the flange portion; and holding members capable of holding the diameter outward parts of the pair of contact members in order to reduce the distance between the pair of contact members. The contact surface between the end faces of the flange portions and the contact surface between the flange portion and the contact member are approximately in parallel. |
