ABSTRACT:
A vibration member of a vibration motor and a method of machining the vibration member to form grooves therein. The bottom of each groove has the shape of an arc of a circle whose center is located on the side of a contact member, e.g., a rotor, so that burrs formed when the vibration member is machined are curved in a direction away from the base portion of the vibration member, i.e., toward the contact member side, and so that the burrs can be easily removed by barrel finishing.
