VIBRATION GENERATING MOTOR

摘要

PROBLEM TO BE SOLVED: To provide a vibration generating motor capable of solving the problem of shock resistance regarding a vibration generating motor, the problem of cost reduction of a vibrator and the theme for taking out large vibrations from a small motor. SOLUTION: The vibrator is constituted with a rotation shaft 2 provided with a recessed part 5, the vibrator impregnated with oil and the end surface of the vibrator in the axial direction thereof which is provided with a difference in level in the vicinity of the rotation shaft. The motor enables increasing holding force of the rotation shaft, eliminating surface treatment of the vibrator and increasing the mass of the vibrator and has a high shock resistant property and large vibration quantity. The vibrator and the motor are provided at a low cost.
