To provide a two axis hinge apparatus which can prevent the looseness between a first hinge member and a second hinge member in a predetermined first position even if a backlash exists between tooth flanks of a first gear and a second gear.
First and second hinge members 23A, 23B are rotatably provided on an aperture side end portion inside an outer case 11. The first and second hinge members 23A, 23B have first and second gears 24A, 24B respectively so as to engage with each other but so as not to turn. Inside the outer case 11, a movable member 25 is provided so as not to turn but so as to access to and separate from the first and second hinge members 23A, 23B. First rotary energizing means for rotationally energizing the first hinge member 23A in one direction are provided between the first and second hinge members 23A, 23B and the movable member 25 respectively.
