Rebar coupler

A rebar coupler comprising:

• a housing which is a cylindrical hollow body having at one end a first opening for receiving a first rebar, at the other end a second opening for receiving a second rebar, to connect the first rebar and the second rebar, and a partition disposed at a center thereof to divide the ends having the first and second openings;
• a mounting member inserted in each end of the housing and receiving the corresponding first and second rebars therein;
• a plurality of coupling members slidably disposed on the corresponding mounting member and being brought into contact with an outer peripheral surface of the corresponding inserted first and second rebars to prevent the first and second rebars from moving out from the rebar coupler;
• a resilient member configured to apply a restoring force to the coupling members so that the coupling members slid by the first and second rebars inserted in the corresponding mounting member are returned to an original position;
• and
• a cover fastened to both ends of the housing to prevent the mounting member and the coupling members from moving out from the housing due to a tensile force of the first and second rebars,
• each mounting members having a plurality of guide portions for guiding sliding movement of the coupling members along an inserting direction of the corresponding first and second rebars, a flange connecting ends of the guide portions, and a contact portion protruding from the flange towards the coupling members.
