PURPOSE: A one-touch type steel reinforcement coupler is provided to join steel reinforcements by a one-touch type in the construction site without processing the end parts of a steel reinforcement and without any additional equipment. CONSTITUTION: A one-touch type steel reinforcement coupler includes a coupler cap(10), an insertion fixture(20), a support ring, a tightening piece(40), an elastic unit(50), a separation blocker(60) and a packing member(70). The insertion fixture is mounted inside the coupler cap. The support ring is connected to a ring connection groove of the insertion fixture. The fastening piece is slipped with a steel reinforcement along a moving direction of the steel reinforcement, composed of restricting the steel reinforcement, and arranged with the support ring as a center in a radial symmetry shape. The elastic unit pressurizes the fastening piece for the front end of the fastening piece to rotate in the opposite direction of the insertion direction of the steel reinforcement with a ring insertion hole as a rotation center. The separation blocker prevents the insertion fixture from breaking away in the direction of the outer end part of the coupler cap. The packing member is formed to wrap around the circumferential surface of a steel reinforcement.
