PROBLEM TO BE SOLVED: To provide the vibration generator of a small-sized radio apparatus which can be integrally formed with a rotary shaft with a sufficiently large drawing force, without causing breakage in the boss, even in the case where a vibrator is made in a small diameter, and in which this additional fastening work can be performed extremely easily. SOLUTION: This is vibration generator, where a vibrator is mounted integrally by additional fastening to a rotary shaft 2 of a motor, and here a vibrator 4 is composed of a boss 42 which has a mounting hole 51 to fit the rotary shaft 2 and an eccentric load 43 made in a body with this boss 42. Furthermore, the rotary shaft 2 and the vibrator 4 are integrally formed with each other by the periphery on both sides of the section, which catches the rotary shaft 2 of a mounting hole 41 in the boss 42 which is additionally fastened toward the side of the eccentric load 43. |
