Since the portion comes into contact with the stopper 14 and stops, the rail fastening clip 4a can be surely stopped at a position displaced by a predetermined amount without removing the rail fastening clip 4a without using the intuition or visual observation when changing the rail setting.

  As a result, when it is not necessary to remove the rail fastening clip 4a from the clip presser 4b when changing the rail setting, etc., if the stopper 4 is attached to the clip presser contact part 12 and used, only a predetermined amount is obtained. While the rail fastening clip 4a can be prevented from being lost after it has been securely moved at the shifted position, the rail fastening clip 4a itself is deteriorated or has a limited service life. Therefore, it is possible to improve work efficiency of track maintenance work such as rail replacement work, rail setting change, and rail fastening clip replacement work.

  In particular, in the rail fastening clip remover 1 of the present embodiment, the stopper 14 is constituted by the stopper bolt 14a and the stopper nut 14b which are longer than the distance between the left and right side surfaces of the clip presser contact portion 12, and thus the stopper. 14 can be easily attached and detached. Also in this respect, the work efficiency of the track maintenance work such as the rail setting change and the rail fastening clip change work can be improved.

  In particular, in the rail fastening clip remover 1 according to the present embodiment, when the operating rod 11 is tilted to the rail 3 side, the rotatable supporting portion 11b is clipped to the rotatable supporting portion 11b at the tip of the operating rod 11. The notch portion 11b3 is provided so as not to interfere (contact) the relay portion 12a2 of the tool abutting portion 12, while the operating rod 11 is tilted toward the hook portion main body 13a of the clip hook portion 13 so that the tip portion is pulled out.
