PROBLEM TO BE SOLVED: To provide a seal in which, even when a roll body is stopped in a place other than the starting point of a printing surface, the printing surface is automatically returned to the starting point position when the printing surface is separated from a sealing surface (automatic heading of the printing surface). SOLUTION: The seal has the roll body 1 on the both sides of which a shaft part 11 is arranged and on the surface of which a printing element 2 is provided. In the seal, the shaft part 11 is pivotally supported rotatably by the bearing part 31 of a supporting frame 3. At least a part of a connection part connecting the shaft part 11 and the roll body 1 is bent at the eccentric position of the shaft part 11 to form a crank arm 13. At a position facing the crank arm 13, a protrusion that is extended from the supporting frame 3 is provided, and a reset spring 4 is stretched between the crank arm 13 and the protrusion.
