Abstract
This hinge device comprises: a hinge element 10 which, along with being made up from an axis body 14 and a hinge main body, is made so that the axis body 14 has a predetermined torque characteristic around an axis relative to said hinge main body; a lock mechanism 30 (a first lock member which has an engagement cutaway 31b, and a second lock member which is biased by a spring 32 in the forwards direction and has an engagement body 34b) which functions so as to lock rotational movement of the axis body 14 around the axis; and a lock release mechanism 40 (a push button 40 having a projection 43) for releasing the locking by the lock mechanism 30. Due to this, it is not necessary for a separate lock mechanism or the like to be provided to a portable electronic device, and it becomes possible to provide a hinge device which contributes to simplification and reduction of space of a portable electronic device.
