ABSTRACT:
In a webbing tension device adapted for use in a webbing retractor wherein clutch means is provided for putting a webbing takeup shaft and an operation wheel biased by resilient means in a connected situation in an emergency situation of an vehicle and for putting them in a disconnected situation in an ordinary running situation of the vehicle, the clutch means is provided with lever means opposed to a gear wheel fixed to the takeup shaft and the lever means is caused to abut on the operation wheel when the lever means is latched to the gear wheel in the emergency situation of the vehicle, whereby a compression force acting upon the lever means in the emergency situation is supplementally sustained.
Accordingly, the lever means is reinforced without using large-sized clutch means.
