PROBLEM TO BE SOLVED: To provide a screw-less terminal block making it possible to determine from the exterior whether an operation lever is at a pressing releasing position or at a position pressing a contact-pressure spring by viewing the operation lever, and making it possible to check that a wire is firmly fastened. SOLUTION: This screw-less terminal device is made up by incorporating, in a case 1, a terminal board 2 mounted with contact-pressure springs 3 for wire fixation and operation levers 8 for pressing and loosening the contact- pressure springs 3. Lock parts 11 for holding the operation levers 8 at pressing releasing positions are provided on the operation levers 8, and locked parts 12 on which the lock parts 11 are locked are provided in the case 1. The operation levers 8 can precisely take up the fixed pressing releasing position, and therefore, by viewing the operation levers 8, it can be checked that a wire 21 is firmly fastened.
