PROBLEM TO BE SOLVED: To easily press-fit a pile into the ground with high precision by clamping an existing pile so as not to be shifted. SOLUTION: This pile press-fitting device 1 is provided with a clamp 20 for clamping the existing pile P, and a pile press-fitting part 10 for pressing another pile P into the ground G with the reaction from the pile P clamped by the clamp 20. The clamp 20 has clamping surfaces 25 and 26 mutually opposed and to interpose the existing pile P between them. The clamping surfaces 25 and 26 have a plurality of protruding parts 30 and 31, the tip surfaces of which abut on the side surface of the pile P. The tip end surfaces of the protruding parts 30 and 31 are formed so that the vertical width is longer than the lateral width. In such a pile press-fitting device 1, the shifting of the clamp 20 to the existing pile P can be prevented by the vertical and lateral edges of the protruding parts 30 and 31 of the clamp.
