1 is a rotating body made of synthetic resin whose base 3 is pivotally supported 4 at a predetermined position on the base 2, and a bell puller 5 is attached to the outer end.
A fan-shaped gear 6 is provided at the front end, an arc-shaped synthetic resin return spring 7 whose base end is connected and integrally formed on the side edge of the base 3 is provided, and a locking ring 8 is integrally molded at the outer end of the spring. It is fitted and supported by the root of a central shaft 9 for attaching a bell bowl, which is erected at the center of the bell bowl. Reference numeral 10 denotes a hammer support frame made of synthetic resin having a support shaft 12 on which a metal hammer 11 is loosely supported at both ends, and a pinion 14 is integrally provided on the lower surface of the ring 13, and this pinion and the ring are used as a central axis. It is pivoted on 9. 15 integrally forms a gear meshed with the pinion 14 and a pinion meshed with the sector gear 6, and the base 2
This is an intermediate transmission gear that is pivotally supported on a support shaft 16 provided in the.

極めて大である。 The present invention has a bell puller 5 and a sector gear 6 as described above.
The rotating body 1 provided with the rotation body 1 and the return spring 7 are integrally molded from a suitable synthetic resin. Since both parts are integrally molded with synthetic resin, unlike conventional metal rotating bodies, manufacturing is significantly simplified, and the material cost is lower than that of metal. If it is made of top metal, it takes time to assemble, especially latching the return spring, resulting in poor productivity and a large impact on production costs, which has the disadvantage that it cannot be produced naturally at low cost.In contrast, in this proposal, the return spring This has the advantage of reducing the number of assembly steps, which reduces production costs considerably, and since almost all parts except the metal base and bell bowl are made of synthetic resin,
It is considerably lighter in weight than conventional metal bells,
This has the effect of greatly reducing transportation costs. In addition, since the return spring is made of resin, it does not apply unreasonable pressure, so there is no need to worry about breakage, and there is no inferiority in durability, action, and effect to conventional metal return springs, making it suitable for practical use. The effect is extremely large.
