る。DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS FIG. 1 is a sectional view showing an essential part of an embodiment of the present invention. A rotary weight 2 is mounted with a gap between the train wheel bridge 1 and a screw 3 fixed to the train wheel bridge 1, and a rotary weight gear 5 is attached to the rotary weight 2 and the rotary weight 2 as described above. It is attached with any frictional force between. An intermediate gear 7 is fixed to the intermediate wheel pinion 6. Therefore, the rotary weight 1 freely rotates due to the movement of the arm or gravity, and this rotation is transmitted to the rotary weight gear 5 by the frictional force between the rotary weight 2 and the rotary weight gear 5, and the intermediate wheel The speed is increased by the pinion 6 and the intermediate wheel gear 7 and transmitted to the rotor 8. A stator 9 is arranged around the rotor 8 to guide a change in magnetic flux generated by the rotation of the rotor 8 to a coil 10 shown in FIG. 2, and the electric power generated in the coil 10 is passed through a charging control circuit 11 to a primary power source 12 Store in. Reference numeral 13 is a timepiece mechanism including an electronic circuit.
【0009】図3は、回転重錘歯車5の平面図である。
前記回転重錘歯車5は5aの部分が径方向にバネ性を持
つているため回転重錘2に取り付けられたとき、前記5
aのバネによって回転重錘2との間に摩擦力を発生させ
ることになる。FIG. 3 is a plan view of the rotary weight gear 5.
Since the rotary weight gear 5 has a spring property in the radial direction at 5a, when it is attached to the rotary weight 2,
A frictional force is generated between the rotary weight 2 and the spring a.
【0010】この摩擦力は、次の関係から設定されてい
る。This frictional force is set according to the following relationship.
【0011】まず、通常時を考えるとスリップせずに伝

負荷より大きな摩擦力になっている。次に衝撃時を考え
ると、磁力による負荷はロータ8の回転速度が速くなる
と電磁誘導作用から大きくなるので、摩擦力はこの負荷
及び先程の機械的な負荷より小さくなっている。First, considering the normal time, since it must be transmitted without slipping, the frictional force becomes larger than the mechanical load such as the load due to the magnetic force generated in the rotor 8 and the stator 9 and the friction in the train wheel. ing. Next, considering the time of impact, since the load due to the magnetic force increases due to the electromagnetic induction effect as the rotation speed of the rotor 8 increases, the frictional force is smaller than this load and the mechanical load described above.
【0012】これらの値は、簡易的に次の考え方で求め
れば実使用を満足する。These values satisfy practical use if simply calculated by the following concept.
【0013】摩擦力の下限値は回転重錘のアンバランス

にIGの加速度が加わるので、これ以上にすれば、負荷
が多少変化してもスリップしてしまうことはない。摩擦
力の上限値は、車のほぞ、歯部等機械的な強度限界より
も小さな値とすれば良い。The lower limit of the frictional force is set to be equal to or more than the unbalance amount of the rotary weight. When carrying the watch gently, use the rotating weight 2
Since the acceleration of the IG is added to the above, if it is more than this, it will not slip even if the load changes a little. The upper limit of the frictional force may be set to a value smaller than the mechanical strength limit such as the tenon or the tooth of the car.
【0014】以上の構成によれば、通常携帯時は、腕の

錘2のトルクが摩擦力を上まわるので、回転重錘歯車5
がスリップし、回転重錘2の回転は回転重錘歯車5以降
の車に伝えられない。According to the above construction, the frictional force is greater than the torque of the rotary weight 2 generated by the movement of the arm or the like during normal carrying, so that the rotary weight gear 5 rotates the rotary weight 2. The torque of the rotary weight 2 exceeds the frictional force when a strong impact such as a drop is applied to the rotary weight 2, but the torque of the rotary weight gear 5 is increased.
Slips, and the rotation of the rotary weight 2 is not transmitted to the vehicles after the rotary weight gear 5.

輪列の増速比分だけ小さくすることができるので、弱い
バネで構成することができる。In the above embodiment, the portion for transmitting power with frictional force is provided between the rotary weight 2 and the rotary weight gear 5, but the invention is not limited to this. There is no problem even if it is provided between the intermediate gear 7. The frictional force in this case is
Since it can be reduced by the speed increasing ratio of the train wheel, it can be configured with a weak spring.
【0016】又、前述実施例では、回転重錘とロータの

ない。In the above embodiment, only one vehicle is placed between the rotary weight and the rotor to increase the speed. However, the present invention is not limited to this, and two or more vehicles are placed. It doesn't matter if you speed up. The portion for transmitting power by frictional force may be provided in any of these vehicles, or may be provided in two or more places.
【0017】又、摩擦力を発生させる構造については、

ど、様々な構造が考えられる。Regarding the structure for generating the frictional force,
The structure is not limited to the above, and various structures such as a well-known method of crushing a cylindrical pinion used as a slip mechanism of a minute wheel and a method of setting a magnetic force of a magnet can be considered.
【0018】磁石を用いた構造の一例を図4に示し、図
に沿つて説明する。15は磁性体よりなる中間車のか
な、16は磁石、17は中間車の歯車を示す。An example of a structure using a magnet is shown in FIG. 4 and will be described with reference to the drawing. Reference numeral 15 is a pinion of an intermediate wheel made of a magnetic material, 16 is a magnet, and 17 is a gear wheel of the intermediate wheel.
【0019】磁石16は歯車17と固着され、歯車17

なる。The magnet 16 is fixed to the gear 17 and
It is engaged with Nokana 15 by looseness. The gear 17 is the magnet 1
It is fixed to the pinion 15 by the suction force of the pinion 6. When the force from the rotary weight is weaker than the suction force, the rotation is transmitted, and when the force is stronger than the suction force, the pinion 15 idles.

トも安くなる。As described above, according to the present invention, the shock resistance performance of the power transmission portion of the rotary weight is dramatically improved as compared with the conventional one. The structure is simple, yet small and thin. Therefore, the electronic wrist watch with a power generator can be made smaller and thinner, and the cost can be reduced.
【0021】また、落下等による衝撃力によりロータが

することができる。Further, since it is possible to prevent the rotor from rotating at a high speed due to an impact force caused by a drop or the like to induce a high voltage in the coil and destroy the charging control circuit, it is possible to ensure the reliability of the circuit.
