接する移動体をステツプ送りする波動ステツプモ
ータにおいて、前記凸部の接触面の移動体進行方
向の幅を、隣合う凸部間の非接触幅よりも小さく
したことを特徴とする波動ステツプモータ。 In a wave step motor that steps a moving body in contact with a contact surface of the convex portion by intermittently moving nodes of vibration formed on a vibrating body provided with a convex portion, movement of the contact surface of the convex portion is provided. A wave step motor characterized in that the width in the body movement direction is smaller than the non-contact width between adjacent convex parts.
