THREADED REINFORCING BAR COUPLING FOR DEFORMED REINFORCING BAR, AND THREADED DEFORMED REINFORCING BAR
A threaded reinforcing bar coupling for a deformed reinforcing bar according to the present invention connects a pair of reinforcing bars (1, 1), which are deformed reinforcing bars, with male threaded portions (1c) provided at end portions of the reinforcing bars and a threaded cylinder (2). In each reinforcing bar (1), by roll forming on an iron wire rod which is a raw material, a projection (1b) on an outer peripheral surface is formed and a diameter enlarged portion which is larger in diameter than another portion is formed in a portion in a longitudinal direction. An outer diameter of the diameter enlarged portion is not larger than a reinforcing bar outermost diameter (D1) including the projection (1a) of the reinforcing bar (1). The male threaded portion (1c) is formed in the diameter enlarged portion by rolling.
