PROBLEM TO BE SOLVED: To provide a vibration reduction structure of a detachable unit by which vibrations occurring in a unit which is attached/detached as required can be effectively reduced by concurrent use of an elastic body and a damping body. SOLUTION: By the vibration reduction structure, vibrations caused in a detachable unit 30 which is freely inserted/drawn out in/of a device 40 are reduced. The device 40 includes a stopper 42 which is arranged almost parallel with the direction for insertion/drawing out of the detachable unit 30, and provided with a stopper 42 protruding toward the insertion side of the detachable unit 30. The detachable unit 30 includes a damping body 32 and a spring part 35. The damping body 32 is fixed to the detachable unit 30 in its one end, and is placed in a gap produced with respect to the device 40, when having been inserted. A spring part 35 is protruded in the direction of insertion of the detachable unit 30 into the device 40, and is fixed to the end on the side of the device 40 wherein the intermediate part is fixed to the end of the device 40 side of the damping body 32. When the detachable unit 30 has been inserted in the device 40, the tip end of the spring part 35 is inserted in the gap between the stopper 42 and the device 40, and the damping body 32 is placed in the gap without leaving a clearance between the device 40 and the detachable unit 30.
