PROBLEM TO BE SOLVED: To provide a crowbar mainly used for joint adjustment in mounting a PC plate in position to prevent damage to the angle of the PC plate. SOLUTION: A crowbar 11 has an end member 13 provided at one end of a rod member 12, the end member 13 being formed with a taper portion 15 and provided with an angle member 14. In joint adjustment of a PC plate, the angle member 14 is put in close contact with the angle of the PC plate while inserting the end member 12 of the crowbar 11 between joints, thus preventing scoop-out at the angle of the PC plate and damage to the angle when the crowbar 11 is moved in the joints.
