A reinforcing pipe 254 is attached to the hook arm 260 on the opposite side of the shoulder portion 270, and the reinforcing pipe 254 is arranged below the rotary shafts 251 and 252. Therefore, it is possible to prevent the reinforcing pipe 254 from coming into contact with the tie plate screw nail 205.

  According to the fourth embodiment, the receiving plate member 244 has a narrow width. Therefore, the receiving plate member 244 can be prevented from coming into contact with the tie plate 8.

  According to the fourth embodiment, in the support plate portion 233 which is the upper surface of the main body base member 231, the reinforcing plate 284 which is formed in a rectangular flat plate shape in accordance with the size of the lower surface of the support plate portion 233 is a support plate. It is attached by welding to the lower surface of the portion 233 in advance. With this configuration, the strength of the main body base member 231 is improved. Therefore, in the attachment procedure of the sleeper fixing device 230, the main body base member 231 is not deformed, and the sleeper 4 can be firmly fixed to the body 1.

  The main body base member 531 in the case where the reinforcing plate 284 is not attached will be described with reference to the drawing. As shown in FIG. 36, the clamp bolt 535 is rotated in the procedure for attaching the sleeper fixing device 530 ( When the main body base member 531 is raised (see the arrow 114 in FIG. 36), the rotary shafts supported by the shaft receiving plate portion 550 of the main body base member 531 are moved along with the rise of the main body base member 531. 551 and 552 are pulled up, and each end side hook piece part 565,567 is locked by the outer side flange 2, while each base side hook piece part 566,568 is locked by the inner side flange 3. At that time, the main body base member 531 rises in a state where the arm hooks 561 to 564 are locked to the respective flanges 2 and 3, so that the center of the main body base 531 to which the clamp bolt 535 is attached deforms and rises (Fig. 36) (see arrow 115 in FIG. 36) and the shaft receiving plate 550 side is lowered (see arrow 116 in FIG. 36).

  Although the embodiment of the present invention has been described in detail above, the present invention is not limited to the above embodiment. The present invention can be modified in various ways without departing from the matters described in the claims.
