Abstract: 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.

Abstract: The present invention provides a terminal-equipped damper device with which it is possible to achieve a reduction in size in a direction intersecting the sliding direction of a rod and leading outward of a case. This terminal-equipped damper device 10 comprises a body case 20, a rod 40, and a damper structure. The rod 40 has a pressing portion 47 that, by means of the sliding position thereof, presses against a first terminal 60 and causes the first terminal 60 to make contact with a second terminal 70. The first terminal 60 is disposed on the outer side of the body case 20 and has a first extending portion 61 that extends in the sliding direction of the rod 40, a first contact portion, and a receiving portion 62 that is pressed by the pressing portion 47. The second terminal 70 is disposed on the outer side of the body case 20 in a position facing the first terminal 69 and has a second contact portion and a second extending portion 71 that extends in the sliding direction of the rod 40.
