The invention is related to a seatbelt webbing lock preventing apparatus enables a flywheel constituted as an inertia mass means to prevent a rotating lock of a lock mechanism followed by the webbing acceleration and deceleration of a seatbelt in any case of withdrawing the seatbelt from a retractor and rewinding it therein. The webbing lock preventing apparatus comprises a webbing control portion 10 including a locking portion with a torsion bar mechanism for limiting a force applied to a seatbelt, a locking actuation mechanism provided with a flywheel for controlling the operating of the locking portion and stopping the rotating of a spool and the webbing of the seatbelt in accordance with the webbing acceleration and deceleration of the seatbelt caused by withdrawing the seatbelt from the retractor and rewinding it thereinto; and a flywheel rotating control portion including a friction spring mounted in a hub of the locking actuation mechanism, thereby preventing the flywheel from being rotated with its inertia force at the time of the acceleration or deceleration of the webbing.
