Claims

[Claims for Utility Model Registration] (1) The webbing pulled out from the layered winding portion of the take-up shaft is wound around the Rotsu roller, and when the take-up shaft stops rotating, the webbing tension increases and the Rotsu roller A webbing lock device that is pressed toward the outer periphery, and a guide means that guides the lock roller and the layered winding portion in a direction toward and away from each other by the webbing tension when the webbing is pulled out;
a webbing having a biasing means, a part of which is in contact with the lock roller, urges the lock roller in a direction away from the layered winding section, and this urging force increases as the lock roller moves toward the layered winding section; A webbing lock device characterized in that the winding force of the winding shaft and the biasing force of the biasing means are balanced in mutually opposite directions during installation, and the lock roller is held at an intermediate portion of the guide means. (2) Claim No. (1) of the above-mentioned utility model registration, characterized in that the guide means is capable of rapidly moving the rock roller toward the layered winding section against the urging force of the urging means when the tension of the webbing increases. The webbing lock device described in section.
