a mounting plate fixed to either one of an upper surface of the door and a lower surface of the frame using a first fastening member; and
a damper device fixed to the mounting plate using a second fastening member placed at a position different from the first fastening member in a thickness direction of the one of the door and the frame, the damper device including
a case,
a linear damper housed in the case,
an arm pivotable about an axis that is perpendicular to the linear damper and configured to operate the linear damper,
a slider disposed between the arm and the linear damper, the slider being configured to slide in conjunction with rotation of the arm, the slider including a slider hole defined therethrough, and
a coupling shaft inserted within the slider hole defined in the slider and on the arm, the coupling shaft configured to move within the slider hole defined in the slider.
2. The damper device set according to claim 1 , wherein at least part of the linear damper overlaps at least part of the first fastening member in plan view of the one of the door and the frame.
3. The damper device set according to claim 2 , wherein the case has a case body bent into U-shape to accommodate the linear damper, and a damper base inserted into the case body.
4. The damper device set according to claim 3 , wherein the arm is configured to rotate with a closing operation of the door, and
the slider is disposed between the case body and the damper base.
5. The damper device set according to claim 1 , wherein
the mounting plate has a base plate configured to be mounted to the door, and a bent piece that, together with the base plate, is bent into U-shape, and
a through-hole for the second fastening member is formed in the bent piece.
6. The damper device set according to claim 1 , wherein the door includes a frame member that is different from the frame, and
the frame member of the door is sandwiched between the mounting plate and a back plate configured to be threadedly engaged with the first fastening member.
