PROBLEM TO BE SOLVED: To provide a connecting fixture of a pile head reinforcing rod capable of improving the mounting work of the pile head reinforcing rod to an existing pile without reducing a connecting force between the existing pile such as a steel pipe pile and a structure, being applicable to a pile head part cut at a high level, and facilitating the reduction of a size. SOLUTION: The cylindrical connecting fixture 2 of the pile head reinforcing rod comprising a combination of a pair of semi-circular arc plates 21, 21 is put to the upper end of the existing pile 1 and the arc plates are tightened in a diameter-shrinking direction by a suitable tightening member such as a bolt and a nut. Accordingly, the inner circumferential surface of the connecting fixture 2 of the pile head reinforcing rod 2 is firmly fixed to the outer circumferential surface of the existing pile 1 in a pressure contact state. The pile head reinforcing rod 3 is supported in an erected state by reinforcing rod supporting members such as a coupler fixed to the outer circumferential surface of the arc plate 21.
