PROBLEM TO BE SOLVED: To provide a partial hitting adjusting device capable of preventing damage to a pile body, by preventing generation of excessive compressive strain in one side surface part of the pile body by partial hitting of a pile head. SOLUTION: This pile head partial hitting adjusting device is arranged on a pile head cap 20, and is characterized by having a lower side spherical surface member 1 fixed on the pile head cap 20 and having a spherical surface 4 on an upper surface, and an upper side spherical surface member 2 placed on this lower side spherical surface member 1 and having a spherical surface 6 fitted to the spherical surface 4 of the lower side spherical surface member 1 on an under surface.
