<p>A damper device includes a protruding portion located outside a closing portion of a cylinder body facing a piston body and forming a flow path communicating inside and outside of the cylinder body; a plug body including a shaft portion inserted into the flow path from an outside of the cylinder body; and an urging device of the plug body. An insertion length of the shaft portion of the plug-like body into the flow path against urging of the urging device increases by change in pressure due to a movement or a relative movement of the piston body in a direction separating from the closing portion of the cylinder body.</p> |
