PROBLEM TO BE SOLVED: To provide an extraction device capable of extracting a coupling automatically from a motor.SOLUTION: A pallet 15 is mounted on a carriage 14 to be able to be lifted and lowered, and lifted up and down by a hand lift. A hydraulic jack 1 is fixed on a pallet 15a of a mounting stand 15, and a claw holder 3 is journaled openably/closably on the hydraulic jack 1. A rod support stand is mounted under the pallet to be taken in and out, a V-shaped pedestal is mounted on the rod support stand through a spacer, and a rod 8 is mounted on the pedestal. When a coupling 9 of a motor 6 mounted on a fixed stand 31 is extracted from a rotor 7, the carriage 14 is moved, and by lifting the pallet 15 up and down, centering is performed through the rod 8 sandwiched between a ram 5 of the hydraulic jack 1 and the rotor 7 of the motor 6. After centering, the claw holder 3 is closed and a claw 3a is engaged with a periphery of the coupling 9. Then, the coupling 9 is extracted by the hydraulic jack 1. |
