る接着あるいはカシメにより固着していた。[Prior Art] A conventional pager is a system in which an alarm device carried by a specific receiver emits an alarm sound in response to a call signal from a caller, and the alarm sound is also emitted to the surroundings. Therefore, there is a drawback that it causes discomfort to persons near the person other than the person himself.Therefore, a device that vibrates the device itself without emitting the alarm sound and directly notifies the wearer of the alarm by vibrating action is available. It is provided. A vibration motor is mainly housed therein, a weight having an eccentric center of gravity is attached to the motor shaft, and vibration generated by rotation unbalance of the motor itself due to rotation of the motor is transmitted to vibrate the entire device. As shown in FIG. 2, the weight having such a structure is formed of a super-polymerized metal having a specific gravity of about 18 g / cm 3 of a W-Mo-Ni-Fe alloy in the shape of a fan plate. No. 2, it was fixed by adhesion through a bush or caulking.

た。[Problems to be solved by the invention] However, since such a structure uses expensive tungsten and molybdenum, the material cost as a weight becomes high, and loosening, omission, or super-polymerized gold due to poor adhesion of the adhesive or deterioration over time. Due to cracking of the weight at the time of crimping due to deterioration of ductility and disconnection from the motor shaft, there were problems with the generation of defects and durability of the vibration motor.

The vibration motor is provided with a weight having an eccentric center of gravity attached to a motor shaft, and the motor is rotated by rotation of the motor. In the weight that generates vibration due to its own rotational unbalance, the motor shaft peripheral part is made of resin, and the motor shaft remote part is made of super heavy metal,
It is to press the weight bodies integrated with each other into the motor shaft. The moment of inertia due to rotation is the product of the square of the distance from the center and the mass, and even if the center portion is made of a lightweight material, it does not substantially contribute to the moment of inertia. Resins include ABS, nylon, PBT, and PPS resins, and super-polymerized gold includes W-Mo-Ni-Fe-based as well as W-Ni-
Examples include Fe-based and W-Ni-Cu-based sintered alloys.
