RULER FOR CONFIRMING RAIL-GRINDING POSITION

PROBLEM TO BE SOLVED: To provide a ruler for confirming rail-grinding position that allows accurate confirmation of grinding position and improvement of working efficiency. SOLUTION: A ruler 1 for rail-grinding includes a frame 3 formed so as to encompass a rail head part 2A; a fixing means 10 for fixing the frame 3 to the rail 2; a moving reference ruler 21, having a reference surface 21a extending in a direction orthogonal to a direction of central axial line O of the rail 2, in a state where the frame 3 is fixed to the rail 2, abutting against a head top surface 2a of the rail 2, and provided to the frame 3 so as to be movable along the direction of center axial line O; and a determination unit 22 which is movable along the reference surface 21a and having a tip indication part 22a, at a position on the side of the rail 2 in the direction of central axial line O from the reference surface 21a.
