A webbing retractor for webbing belt retraction and restraint of a vehicle occupant during sudden deceleration. In a preferred embodiment, the webbing retractor includes a spring, and is for connection to an axially rotatable shaft having a locking device. The locking device includes a rotator coaxially rotatable with the shaft and a locking mechanism. The spring resiliently urges the shaft to retract the webbing belt, which can be ordinarily unwound against the spring tension. During sudden deceleration, the locking mechanism is activated and limits or prevents unwinding of the webbing belt. The retractor includes wall portions provided at the rotator and the shaft, with the spring disposed between these portions. A hole for insertion of the spring is provided between the wall portions. The hole is sized such that the spring must be at least partially compressed for insertion therethrough. The arrangement facilitates insertion of the spring, and stable connection of the spring in the assembly.
