Abstract: A damper includes a cylinder, a rod including a first engaging portion at a tip end thereof, and a piston formed of an elastic resin material. The piston includes a convex portion provided so as to protrude at a base end portion located on a rod base end side and always in pressure contact with an inner circumference of the cylinder. During damper braking, the first engaging portion of the rod abuts against the other end portion of the piston, and an axial compression force acts on the piston between the first engaging portion and the convex portion in pressure contact with the inner circumference of the cylinder.

Abstract: A damper device provided between a fixed body having an opening portion and an openable and closable body mounted on the opening portion and configured to apply a braking force to the openable and closable body. An elastic resin member is mounted on a projecting portion provided on the openable and closable body. A receiving recess portion is provided on the fixed body to receive the elastic resin member. The elastic resin member has a base portion; a pair of arm portions; a bridge portion; and a stopper, which are formed integrally. The receiving recess portion has: an introducing portion configured to abut with the arm portions to bend them diametrically towards each other; and a restricting portion configured to abut with the stopper to restrict the openable and closable body from opening, when the openable and closable body opens to cause the elastic resin member to move.

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.
