Hinge

A hinge (10, 80) that supports a first member and a second member such that the first member (51) and the second member (52) are rotatable about a virtual rotation axis (A), the hinge (10, 80) comprising:

• a first hinge shaft (17) parallel to the virtual rotation axis (A);
• a second hinge shaft (19) parallel to the virtual rotation axis (A);
• A first link shaft (23) parallel to the virtual rotation axis (A);
• a second link shaft (25) parallel to the virtual rotation axis (A);
• a center shaft (27) parallel to the virtual rotation axis (A);
• a first case (11) attached with the first member (51), the first case including an insertion hole (11d) through which the first hinge shaft (17) is inserted, and a guide groove (11g) that guides the first link shaft (23);
• a second case (12) attached with the second member (52), the second case including an insertion hole (12d) through which the second hinge shaft (19) is inserted, and a guide groove (12h) that guides the second link shaft (25);
• and
• a first plate (14, 84) including an insertion hole (14a) through which the first hinge shaft (17) is inserted, an insertion hole (14c) through which the second link shaft (25) is inserted, and an insertion hole (14b) through which the center shaft (27) is inserted;
• and
• a second plate (15) including an insertion hole (15a) through which the second hinge shaft (19) is inserted, an insertion hole (15d) through which the first link shaft (23) is inserted, and an insertion hole (15c) through which the center shaft (27) is inserted.
