Abstract
A device for maintaining a biasing state of a biasing force application means used in a seat belt retractor. The inner end (8a) of a power spring (8) of the biasing force application means (5) is retained by a bush (9), and the outer end (8b) of the power spring (8) is retained by a retaining portion (10d) of a spring casing (10). In a state where the biasing force application means (5) is formed as a subassembly and the power spring (8) has been wound up by a predetermined amount in a direction in which a webbing (3) is unwound, a spring pin (12) is attached to the subassembly so that a pair of rotation preventing arms (12a) and (12b) of the spring pin (12) pierce through small holes (11b and 11c) provided in a cover (11), either of grooves (9b and 9c) and either of grooves (9 d and 9e), which are provided in the bush (9), and small holes (10b and 10c) provided in the spring casing (10), thereby enabling the power spring (8) to be readily maintained in the wound-up state.
