PROBLEM TO BE SOLVED: To provide an end structure of a prestressed concrete pile capable of solving problem of a conventional one wherein if an unexpected bending tension is applied to a place joined to a pile by a large earthquake, cracks occur in a concrete body at the rib of a reinforcement band, and a structure cannot be stably supported due to the shortage of a bearing force. SOLUTION: This end structure of the prestressed concrete pile includes an end plate 1, a tendon 2, and a concrete body 3. The end plate 1 is formed in a ring shape and radially comprises locking holes 11. The tendon 2 comprises a head part 21 at one end. The head part 21 is locked to the locking holes 11 of the end plate 1 so as to introduce a tension thereto. The concrete body 3 is fitted to the end plate 1 at one end, and extends to the other end while enclosing the tendon 2. The tendon 2 comprises at least one protrusion 22 in the concrete body 3 separately from the head part 21. COPYRIGHT: (C)2010,JPO&INPIT
