Claims

[Claims for Utility Model Registration] (1) When the webbing is suddenly pulled out, a delay is caused in the locking wheel to which the rotation of the take-up shaft is transmitted via the biasing means, and the delay in the locking wheel causes the locking means to be locked. The lock mechanism is used in a lock mechanism for a webbing retractor that can stop the rotation of the take-up shaft in the webbing pull-out direction by activating the first gear. The gear is a second gear that rotates with variable speed, and a second gear that rotates with a changed speed.
contact means, comprising contact portions provided corresponding to the gear and the lock wheel, and these contact portions contact each other near when the webbing is fully wound to prevent rotation delay of the lock wheel; A lock mechanism for a webbing retractor. (2) The above-mentioned device characterized in that the movement trajectories of the respective abutting portions of the abutting means partially intersect, and a phase difference is set by the gear ratio of the first and second gears. A lock mechanism for a webbing retractor as set forth in claim (1) of the utility model registration.
