Claim 4:
5. A single-axis hinge comprising:
a first member attached to a main body;
a second member which is attached to a door and can rotate with respect to the first member around a shaft facing a vertical direction;
a catch mechanism having a spring and giving rotational force in a closing direction to the door in the vicinity of a closed position; and
a damper mechanism having a linear damper and damping rotation of the door when the door is closed,
wherein the catch mechanism and the damper mechanism are disposed on either one of the first member and the second member,
an other of the first member and the second member has a cylindrical portion through which the shaft is inserted,
a cylinder portion and a concave portion are formed on an outer surface of the cylindrical portion,
a protrusion for operating a slider of the damper mechanism is further formed on an outer surface of the cylindrical portion,
wherein when the first member and the second member transition from a folded state to an unfolded state, the catch mechanism generates rotational force so as to unfold the first member and the second member in the vicinity of the unfolded state,
wherein a curved concave portion complementary to a cylinder portion of the outer surface of the cylindrical portion is formed on the slider of the damper mechanism, and wherein a slider of the catch mechanism is biased onto the outer surface of the cylindrical portion by the spring.
