があった。In the prior art described above, since the weight 21 is attached to the output shaft 20 of the motor, it is necessary to widen the gap so as not to come into contact with other parts by rotation. In addition, the weight 21 needs to be increased in order to obtain strong vibration, which is a serious obstacle for a pager or the like that needs to be downsized.

ットである。The embodiments of the present invention shown in the drawings will be described in detail below. The magnets 2 and 3 having the inner surface of the arc are fixed to the case 1 of the magnetic body so as to face each other to form a fixed body. Reference numeral 4 denotes a rotating body around which coils 5a, 5b and 5c are wound, and a through hole 8 is formed along an axis 7 at an eccentric position of the rotating body 4. Among the three coils of the rotating body 4, the wire diameter of the coil 3c in the vicinity of the through hole 8 is made extremely smaller than the wire diameters of the other coils 3a and 3b, and the rotational weight balance of the coil itself is unbalanced. 1
Brushes 1a and 11b are connected to the terminals 12a and 12b. Reference numeral 9 is a bearing, and 13 is a bracket of the terminals 12a and 12b.
