VIBRATION GENERATOR FOR SMALL-SIZED RADIO CALLING SET

摘要

PURPOSE:To obtain the vibration generator for the small-sized radio calling set in which the assembling is simplified and no residual stress or the like losing durability to a vibrator and a rotary shaft is caused with excellent strength of the vibrator. CONSTITUTION:This vibration generator is constituted motor and a vibrator 10 made of a high specific gravity metal eccentrically fixed to a drive shaft 2 of the motor, a mount hole is formed to the vibrator 10 at its eccentric position, the drive shaft 2 of the motor is inserted to the mount hole and fixed to the drive shaft 2 by being tightened front one point 14 and two points 15, 16 having the position 14 inbetween in a direction of an axial line C from the other side at a position deviated radially with respect to a plane including the axial line C at an outer circumferential part of the drive shaft 2.
