Abstract
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.
Claims5
A damper device including a cylinder body and a piston body, and applying a braking force to act on a movement or a relative movement of an object to be braked by attaching at least one of either the cylinder body or the piston body to the object to be braked, comprising:
- a protruding portion forming a flow path, communicating inside and outside of the cylinder body, outside a closing portion of the cylinder body facing the piston 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-like body,
- wherein an insertion length of the shaft portion of the plug body into the flow path against urging of the urging device increases by a 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.
