Abstract:
A video image display apparatus is configured such that a monitor case includes a first gear unit that rotates according to a screen angle of the monitor case, and a clutch mechanism includes: a first torsion coil spring; a second gear unit that is meshed with the first gear unit, wherein a cylindrical portion is fitted to one end of the first torsion coil spring so as to rotate; a cam unit that rotates with a cylindrical portion being fitted to the other end of the first torsion coil spring; and an engagement unit that restricts the rotation of the cam unit, wherein when the screen angle of the monitor case is changed in a near direction, the restriction for the rotation of the cam unit by the engagement unit is removed, and the second gear unit, the first torsion coil spring, and the cam unit are rotated as being interlocked with one another, and when the screen angle of the monitor case is changed in a push-in direction, the restriction for the rotation of the cam unit by the engagement unit is not removed, and only the second gear unit is rotated through the first torsion coil spring.
