PROBLEM TO BE SOLVED: To provide a pile chuck device that is configured to fix a pile to a construction machine such as a pile press-in machine and that facilitates replacement of teeth formed on surfaces, abutting on the pile, of claws holding the pile. ! SOLUTION: A pair of claws 101, 102 holding a pile has teeth 21 formed on surfaces abutting on the pile respectively, and guide surfaces 31, 32 and 51, 52 formed above and below abutting surfaces while retracted from the abutting surfaces obliquely in a leaving direction (X) so as to guide a plate-like part of the pile to the gap where the abutting surfaces face each other. At least one claw 101 between the pair of claws is a movable claw 101. The movable claw 101 comprises a tooth part 20 having teeth, and a claw body 30 which has a fitting part 40 fitted with the tooth part and the guide surfaces 31, 32, and is fixed to a movable end of an actuation cylinder. The fixed claw 102 comprises a tooth part 20 having teeth, and a claw body part 50 which has a |
