A damper device includes: a cylinder having a vent hole and a valve seat; and a piston. An elastically deformable valve body abuts against the valve seat before and when the piston moves in a damper braking direction. The valve seat is formed with a vent groove. A protrusion amount of an inclined surface gradually decreases from a side of an outer periphery of the valve seat toward the vent hole. The vent groove includes a first groove that extends from an outer periphery of the inclined surface toward the vent hole such that a depth thereof with respect to the inclined surface gradually decreases. When the piston moves in the damper braking direction, the valve body comes into contact with the inclined surface and is elastically deformed, and a contact area with the inclined surface widens.
