A wall portion of a dental handpiece accommodates a cam pinwith a cam holeor a cam groovedesigned so that the size of the cam holeor the cam grooveis larger than the size of the cam pinin each of the axial direction and the circumferential direction of a vibration cylinder. Therefore, a rotating memberis rotationally driven, and a vibrating force acts on the vibration cylinderin the axial direction through the cam pin. In this manner, the vibration cylindervibrates or reciprocates in the axial direction with respect to a second cylindrical member, and vibrates or reciprocates in the circumferential direction. In addition, a needle portionprotruding from a through-holeof the vibration cylindervibrates while being bent.
