Abstract
A first abutment surfacefor restricting an initial position of a hinge main body, and a second abutment surfacefor restricting a terminal position of the hinge main bodyare formed on the transmission case. A third abutment surfacefor restricting an intermediate position of a reception caseis formed on the reception case. Between the transmission caseand the hinge main body, there are provided a first turn biasing means (not shown) adapted to turn bias the hinge main bodyto the initial position, and a second turn biasing means (not shown) adapted to turn bias the hinge main bodyto the terminal position. Between the reception caseand the hinge main body, there are provided a third turn biasing means (not shown) adapted to turn bias the reception caseto a folded position, and a fourth turn biasing means (not shown) adapted to turn bias the reception caseto 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.
