A first leg 23 inserted into a first inclined groove 30 of a bed plate 3 is projected downward from an outer bottom face 22 of a body 2'. A second inclined groove 24 is recessed on the upper surface of the body 2' corresponding to the first leg 23. A first through hole 25 is inserted in the body 2' for loosely inserting a shaft 40 of a bolt 4. An abutting face 53 with the washer 2 is formed inside the bottom face of the rail brace 5. A second leg 50 to be inserted into the second inclined groove 24 is provided projecting downward. A second through hole 51 for inserting the shaft 40 of the bolt 4 into the rail brace 5 is formed.
