Abstract
Disclosed herein is a wave generator for a reducer of a harmonic drive structure. The reducer of a harmonic drive structure includes: a circular spline of a ring shape; a flex spline mounted inside the circular spline and having teeth engaged with teeth formed at three or more positions of the inner circumferential surface of the circular spline to be rotated; and a wave generator mounted inside the flex spline, and including a cam plate of a circular shape, and three or more protrusions formed at three or more positions of the outer circumferential surface of the circular cam plate so that the protrusions formed on the outer circumferential surface of the cam plate elastically deform the three or more positions inside the flex spline.
