Abstract
A gear reducer for reciprocal rotation wherein the rotation of a motor 1 is transmitted to a worm pinion 4 integrated with an input shaft 2, and is further transmitted to a helical worm wheel 10. The helical worm wheel 10 and an eccentric member 11 are spline coupled to each other, and a pin flange 13 is rotated by a planetary gear structure of a trochoid-tooth-profile inscribing type. Consequently, a pinion shaft (output shaft) 14 integrated with the pin flange 13 rotates, and an outside gear 19 rotates.
