PROBLEM TO BE SOLVED: To provide a slide type binder without breaking a binder itself even by erroneously opening or closing a binding ring by a user and having excellent operability. SOLUTION: First and second locking means provided at both ends of first and second base plates 2, 3 respectively have operating pieces 55, 58 formed by being projected upward from plate members 53, 55. In this case, when forces are applied to the pieces 55, 58 toward one another to disengage the locking pawl 4 of the first locking means from the first locking projection 57 of the second locking means. Thus, the first and second plates 2, 3 are relatively moved from the closed state to the open state.
