ABSTRACT:
A bracket angle adjustment mechanism has two wedge members (16A,16B) fit in an eccentric space between a large-diameter hole (14c) of an external-tooth gear (14) and a small-diameter shank (15c) of an internal-tooth gear (15), and a wedged-state release member (19) is held by the external-tooth gear (14) so that an outer peripheral surface of the wedged-state release member (19) is fit rotatably into the large-diameter hole (14c). The wedged-state release member (19) has a clearance groove (19a) for avoiding interference with the wedge members (16A,16B), a wedged-state release portion (19e), and a noncircular mounting hole (19d) non-rotatably fit with a attaching portion of a control shaft (20) penetrating through the small-diameter shank (15c) in a non-fitting manner. The bracket angle adjustment mechanism achieves enhanced strength and lower production cost, based on the improved mounting position of the wedged-state release member.
