PURPOSE: A dowel bar used between precast structures is provided to efficiently connect adjacent precast structures to each other even if the weight and volume of the precast structures are high. CONSTITUTION: A dowel bar(100) used between precast structures comprises a cylindrical main body(110), a rod(130), a compression spring(120), and a latching pin(116). One end of the main body is closed, and the other end has through holes(114). The rod is slidably inserted into the main body. One end of the compression spring is fixed to the rod, and the other end is supported to one end of the main body. The latching pin is inserted into the through holes of the main body and prevents the rod from being separated from the main body.
