Apparatus incorporating a motion damper

[Subject] It is in offering the motion damper which can be manufactured cheaply compactly easily [a design] therefore. [Solution means] The motion damper of the present invention has a damper wall (16), and the damper stage (14) and a damper head (12). Size is small continuously and a damper wall and the damper stage have overlap relations. Each of a damper wall and the damper stage is flexibly attached to the contiguity damper stage or a damper wall so that the damper stage may operate in a nest type mode in the direction which separates from a damper wall. The damper wall is attached to the minimum damper stage. Thereby, the position and the relative position of damper stages to a damper wall change, and the damper stage absorbs the kinetic energy of the object attached to the damper head and the damper wall.
