Abstract
A damper device includes a cylinder body and a piston body. At least one of the cylinder body and the piston body is attached to an article subject to damping so that the damping is applied to a movement or a relative movement of the article subject to the damping. The damper device has a run-through hole formed in an inner recess part of the cylinder body facing the piston body, and a stopper body having a shaft part, which is inserted into the run-through hole. A dimension of insertion of the shaft part of the stopper body into the run-through hole changes by a change of pressure caused by a movement of the piston body.
