PROBLEM TO BE SOLVED: To provide a small-sized motor for vibration generation which is capable of surely fixing a vibrator to a revolving shaft in a non-rotating state relative to the revolving shaft with large holding force so as not to move in a thrust direction. SOLUTION: The small-sized motor 1 for vibration generation fixes the vibrator 5 to the revolving shaft 3 by forming an output section 4 of the revolving shaft 3 to a cross-sectionally irregular shape other than a cross-sectionally circular shape, forming an engaging hole 15 having a prescribed cross-sectional shape which corresponds to the cross-sectionally irregular shape of the output section 4 and puts the vibrator 5 into the non-rotating state relative to the revolving shaft 3, engaging the output section 4 with the engaging hole 15 and positioning and holding the vibrator 5 in the thrust direction with respect to the output section 4. |
