PROBLEM TO BE SOLVED: To more efficiently perform a liner inserting work in the centering of a guide rail by providing extension parts extended upward from the contact position to the contact surface of a rail bracket, a connection part for connecting both upper ends of the extension parts to the back surface of the guide rail, and horizontal parts orthogonal to both lower ends of the extension parts. SOLUTION: A centering device 1 comprises a pair of extension parts 1b butted to the contact surface 3a of a rail bracket 3 on both sides of a guide rail 2 and extended upward from the contact position, a connection part 1a connecting both upper ends of the extension parts 1b, which is butted to the back surface 2a of the guide rail, and a pair of horizontal parts 1c extended from the both lower ends of the extension parts 1b orthogonally thereto. When the horizontal parts 1c are moved in a direction A to transmit a B-directional force to the connection part 1a with the lower ends of the extension parts 1b as fulcrums, and a clearance is formed between the back surface of the rail 2 and the contact surface 3a, a liner 8 can be inserted without adding a large force. Accordingly, the efficiency of the liner inserting work in the centering of the guide rail can be improved.
