Abstract
The present invention relates to a self-locking device the self-locking of which can be released. The device may comprise: a locking lever that rotates around a first hinge shaft and has an engaging portion formed at one part thereof to be engaged with a power transfer device, and a catching portion formed at another part thereof; a release lever that rotates around a second hinge shaft and has a stopper portion formed at one part thereof to be caught by and coupled to the catching portion of the locking lever, and an application portion which is formed at another part thereof and to which an operating force is applied; and an elastic member for applying an elastic restoring force in an advancing direction in which the engaging portion of the locking lever moves forward to be engaged with the power transfer device and the stopper portion of the release lever moves forward to be caught by and coupled to the catching portion of the locking lever.
