Abstract
In a webbing tension device adapted for use in a webbing retractor for a vehicle in which a takeup shaft retracting an occupant restraining webbing thereon is biased in a direction of a webbing retraction by small resilient means and in an emergency situation of the vehicle a biasing force of large resilient means is transmitted to the takeup shaft through one clutch means so that the takeup shaft is biased in the direction of the webbing retraction by the large resilient means, another clutch means is disposed between the takeup shaft and the large resilient means. Accordingly, when the webbing is fully retracted on the takeup shaft after the vehicle is released from the emergency situation, the another clutch means is put in its connected situation, and when the webbing is unwound from the takeup shaft after it is retracted fully on the takeup shaft, an unwinding rotation of the takeup shaft is transmitted to the large resilient means, so that the large resilient means is wound up.
