A bidirectional push-pull door lock body including a driving circulation unit is provided to conveniently open a door together with a locking cancel of a mortise by pushing/pulling an operation lever having a bidirectional circulation function. An operation lever(60) is combined with door lock bodies(10a,10b,10c,10d) of an indoor and outdoor side closed by a cover member(15). One side of the door lock body of an indoor and outdoor side is coupled with a hinge. A connection circulation body is circulated into up/down direction by combining in a bottom of the operation lever. A slide member(30) is installed at an inner side of the door lock body, has a to-and-fro motion corresponding to the connection circulation. A driving circulation unit operates a driving part within a mortise for a locking cancel of the mortise. The driving circulation unit is installed at the inner side of the door lock body, and is connected to the mortise for a locking unit.
