Abstract
In a rack and pinion mechanism, a driving-side pinion gearand a driven-side pinion gearare provided to be coaxially rotatable relative to each other within a predetermined angle range. Because of this construction, in a case where a time when a driverreaches an advancing end position and contacts an advancing end damperdeviates from a time when a weight devicereaches a retracting end position and contacts a moving end damper, an excessive external force is not applied to engaging teethandby relative rotation of the pinion gearsand. Thus, due to this construction, durability of the rack and pinion mechanism, where end impacts are absorbed through elastic deformation, is improved.
