  "textContent": "In a structure in which loss of threaded engagement of a pinion gear and a sector gear is prevented by maintaining the pinion gear and the sector gear in a state of threaded engagement using a bracket, an increase in structural complexity is unavoidable. Thus, an oblong hole (36a) of an arc shape is formed about a stabilizer (34) in a sector gear (36), an inner edge of the oblong hole is provided with teeth, and a pinion gear (38b) is inserted in the oblong hole and engaged with the teeth on the edge of the oblong hole. As the left and right ends of the oblong hole of the sector gear abut on the pinion gear (38b) inserted in the oblong hole, swinging of the sector gear is limited. Further, an end (38b') of the pinion gear protruding from the oblong hole (36a) of the sector gear is provided with a stepped reduced-diameter portion, with a nut (38e) threadedly mounted to a male screw formed on the reduced-diameter portion, and a stopper is held between the nut and the step at the end of the pinion gear to prevent movement of the sector gear in a direction away from the pinion gear.",
