Abstract
A vibration type motor includes a vibration plate configured to vibrate by a piezoelectric element, a friction member including a contact surface for the vibration plate, and configured to move relative to the vibration plate as the vibration plate vibrates, and an adhesive member provided on the contact surface of the friction member. The vibration plate includes a protrusion that protrudes toward a side opposite to the piezoelectric element. The protrusion includes a sidewall portion, at least one contact portion that contacts the contact surface, and a flat portion provided between the contact portion and the sidewall portion. The adhesive member has an opening that avoids a moving range of the contact portion. The opening in the adhesive member is located outside the sidewall portion. An end of the adhesive member is located outside the friction member.
