Abstract
A tube expansion tool for expanding an end of a synthetic resin fluid pipe has a motor shaft rotated by an electric motor, a feed screw mechanism for converting rotation of the motor shaft into front-and-rear movement of an output shaft, a wedge provided on a front portion of the output shaft for pushing a plurality of jaws. The plurality of jaws mutually opens radially outward. The tube expansion tool further has a jaw rotation mechanism and a shaft. The shaft rotates around an axis in conjunction with the rotation of the motor shaft. The shaft rotates the plurality of jaws around its axis. The output shaft, the motor shaft, and the shaft of the jaw rotation mechanism are arranged in parallel with each other and overlap in the front-rear direction.
