機構である。FIG. 1 is a sectional view of an essential part showing an embodiment of the present invention. A rotary weight 2 is attached with a gap between a wheel train receiver 1 and a screw 3 fixed to the wheel train receiver 1, and a rotary weight gear 5 is attached to the rotary weight 2 with the rotary weight 2. It is attached with an arbitrary frictional force between them. An intermediate gear 7 is fixed to the intermediate wheel 6. Accordingly, the rotating weight 1 is freely rotated by the movement of the arm or the actual force, and this rotation is transmitted to the rotating weight gear 5 by the frictional force between the rotating weight 2 and the rotating weight gear 5, The speed is increased by the intermediate wheel pinion 6 and the intermediate wheel gear 7 and transmitted to the rotor 8. A stator 9 is arranged around the rotor 8, and guides a change in magnetic flux generated by the rotation of the rotor 8 to the coil 10 shown in FIG. 2, and transfers the electric power generated in the coil 10 to the secondary power supply via the charge control circuit 11. Store in 12. Reference numeral 13 denotes a clock mechanism including an electronic circuit.

When the rotary weight gear 5 is attached to the rotary weight 2 because the portion 5a has a spring property in the radial direction,
A friction force is generated between the rotary weight 2 and the spring by the spring a.

ば良い。The frictional force is set based on the following relationship. First, since transmission must be performed without slipping in a normal state, a frictional force greater than a mechanical load such as a load due to a magnetic force generated in the rotor 8 and the stator 9 and a friction in a wheel train portion is generated. Next, considering the time of impact, the load due to the magnetic force increases due to the electromagnetic induction when the rotation speed of the rotor 8 increases, so that the frictional force is smaller than this load and the mechanical load. These values are
If it is simply obtained by the following concept, actual use will be satisfied. The lower limit of the frictional force should be equal to or greater than the imbalance of the rotating weight. When the watch is carried quietly, an acceleration of 1 G is applied to the rotary weight 2, so if the load is increased beyond this, no slip will occur even if the load slightly changes. The upper limit of the frictional force may be set to a value smaller than the mechanical strength limit of a tenon, teeth, and the like of a vehicle.

箇所以上に設けてもかまわない。According to the above configuration, the frictional force is larger than the torque of the rotating weight 2 generated by the movement of the arm and the like during normal carrying, so that the rotating weight gear 5 rotates the rotating weight 2. Is transmitted to the intermediate wheel kana 6 and the rotor 8 as it is. For example, when a strong strike such as a drop is applied to the rotary weight 2, the torque of the rotary weight 2 exceeds the frictional force. 5
Slips, and the rotation of the rotary weight 2 is not transmitted to the vehicle after the rotary weight gear 5. In the case of the above-described embodiment, the portion that transmits power with frictional force is formed by the rotating weight 2 and the rotating weight gear 5.
However, the present invention is not limited to this, and there is no problem if it is provided between the intermediate pinion 6 and the intermediate gear 7, for example. Since the friction force in this case can be reduced by the speed increase ratio of the wheel train,
It can be composed of a weak spring. In the above-described embodiment, the speed is increased by disposing only one vehicle between the rotating weight and the rotor. However, the present invention is not limited to this, and the speed is increased by disposing two or more vehicles. It does not matter. A portion for transmitting power by frictional force may be provided in any of these vehicles.
It may be provided in more than places.

置の小型化，薄型化が可能となり、コストも安くなる。As described above, according to the present invention, there is provided a power generator comprising a rotating weight serving as a power source, a rotor, a stator, and a coil for converting mechanical energy into electric energy. In a power generating device having an intermediate wheel that transmits power from the weight to the power generating device, by providing a slip mechanism between the pinion and the gear of the intermediate wheel, the friction force of the slip mechanism is reduced by the speed increase ratio of the wheel train. Since it can be made smaller, a slip mechanism with weak frictional force is possible. Therefore, the impact resistance is dramatically improved as compared with the conventional one, so that the structure for supporting the power transmission unit, the gears and the pinion are simple, compact, and compact. Therefore, the size and thickness of the power generation device can be reduced, and the cost can be reduced.
