Abstract

A first abutment surface 24 for restricting an initial position of a hinge main body 5, and a second abutment surface 25 for restricting a terminal position of the hinge main body 5 are formed on the transmission case 2. A third abutment surface 34 for restricting an intermediate position of a reception case 3 is formed on the reception case 3. Between the transmission case 2 and the hinge main body 5, there are provided a first turn biasing means (not shown) adapted to turn bias the hinge main body 5 to the initial position, and a second turn biasing means (not shown) adapted to turn bias the hinge main body 5 to the terminal position. Between the reception case 3 and the hinge main body 5, there are provided a third turn biasing means (not shown) adapted to turn bias the reception case 3 to a folded position, and a fourth turn biasing means (not shown) adapted to turn bias the reception case 3 to a transmission position. The turn biasing force of the first turn biasing means is larger than that of the third turn biasing means. The turn biasing force of the fourth turn biasing means is larger than that of the second turn biasing means.
