PROBLEM TO BE SOLVED: To provide a stopper structure which can absorb mechanical shock. SOLUTION: The stopper structure comprises a pillar shape shock buffering body 25 and a hole 23 which can accommodate the shock buffering body and includes a block body 24 from which a part of the tip portion of the shock buffering body is exposed from the hole when the shock buffering body is stored fixedly in the hole. The shock buffering body is made by the material which is accommodated fully in the hole of the block body when the load is acting on the tip of the shock buffering body, and the shock buffering body has elasticity which allows a part of the tip portion thereof to expose from the block body when the effect of the load disappeared.
