ABSTRACT:
A hinge supporting first and second portions such that they are open and closed relative to each other, including a rotation shaft fixed to the second portion and supported by the first portion so as to be rotatable around a rotation axis thereof relative to the first portion, first and second parts into which the rotation shaft is inserted, and an energizer for pushing the movable part towards the fixed part. The first part is fixed to the first portion so as to be rotatable around the rotation axis relative to the first part. The second part is axially movable relative to the rotation shaft and not rotatable around a rotation axis thereof, and rotates together with the rotation shaft. Each of the first and second parts has a projection projecting towards each other. The projections overlap each other axially of the rotation shaft when the first and second portions are open each other at a certain angle in the range of predetermined angles.
