    Abstract: A hinge, for automatically-closing a door which opens in both directions, includes a cylinder (2); an operating rod (3) to be rotatable and restricted from moving in the longitudinal direction; two substantially V-shaped grooves (33) provided on an outer periphery of the operating rod (3) in the cylinder (2) to oppose to each other; two spheres (55) provided engage the substantially V-shaped grooves (33); an upper piston (5) engaged with the spheres (55); a compression coil spring (4) disposed between the upper piston (5) and an upper end portion of the cylinder (2) and configured to urge the upper piston (5) to the other end side of the cylinder (2), and a fluid pressure shock absorbing mechanism configured to absorb a shock caused by the movement of the upper piston 5 to the other end side with a liquid pressure.
