ABSTRACT:
In a webbing tension device adapted for use in a webbing retractor, winding means includes a worm rotated by an occupant and a worm wheel to which a rotative operation force to the worm is subjected to reduction to be transmitted, and a rotation force of the worm wheel is transmitted through clutch means to large resilient means biasing a webbing takeup shaft in a direction of a webbing retraction. Accordingly, after a vehicle is released from an emergency situation, the worm can be rotated against a biasing force of the large resilient means so that the large resilient means is wound up.
