To provide a technique that can suppress so-called "galling", which may occur between a partial pinion gear and a rack gear teeth, without adding any structural elements.SOLUTION: A lock rotating plate 160 that rotates coaxially with a partial pinion gear 150 has: a large diameter part 162 that can be engaged with a lock fixing plate 180; and a small diameter part 164 that cannot be engaged with the lock fixing plate 180. In the lock rotating plate 160, a first boundary 166 between the large diameter part 162 and the small diameter part 164 is located at a tooth tip intermediate portion at one end of five gear teeth 151 of the partial pinion gear 150, and a second boundary 167 between the large diameter part 162 and the small diameter part 164 is located near the tooth tip intermediate portion of the gear tooth at the other end. When the partial pinion gear 150 is disengaged from a rack 170, the large diameter part 162 and the lock fixing plate 180 face each other with a gap g.SELECTED DRAWING: Figure 8
