PROBLEM TO BE SOLVED: To provide a damper in which viscous fluid is settled to charge at a time, it is possible to reduce a time for tuning up, or it does not need to take the time for tuning up separately. SOLUTION: The damper is comprised of a housing main body 2 and a cap 9. The damper is provided with a cylindrical housing 1 in which concentric walls 4, 5, 7I, 7O, 11, 12, 13I and 13O are formed inside the bottom and the roof in which the housing main body 2 and the cap 9 are opposed, a rotor 21 in which concentric cylindrical walls 25I, 25M and 25O fitted in the clearance of the concentric walls 4, 5, 7I, 7O, 11, 12, 13I and 13O are formed in both the sides of a disk-like part 22, and which is rotatably housed in the housing 1, the viscous fluid 31 charged in the housing 1, and O-rings 41 and 42 to protect the viscous fluid 31 from leaking from the clearance between the housing 1 and the rotor 21. A plurality of through holes 22i, 22m and 22o are circumferentially formed in the part of the disk-like part 22 sandwiched by a support shaft 24 and the cylindrical walls 25I, 25M, and 25O.
