Abstract
A retractor shaft-rotating type seat belt pretensioner for imparting pretension to a seat belt by rotating the take-up shaft of a belt retractor comprises a driving member engageable with a driven member on the take-up shaft and a power source coupled to the driving member and adapted to rotate the driving member by applying an operating force to it at an operating point. A guide surface supports the driving member at a reaction support point against the reaction force due to a rotary moment applied to the driving member at an engaging point where the driving member engages the take-up reel, the reaction support point being on the opposite side of the engaging point from the operating point where the operating force of the power source acts on the driving member.
