あつた。 1 to 3 are main part configuration diagrams for explaining an example of a conventional gas meter. In the figures, 10 is a gas meter main body, and 20 is an integrated display of the flow rate of gas passing through the gas meter main body. Counter section, 3
0 is the cover of the counter 20, as is well known,
Gas enters the gas meter body 10 through the inlet 11, exits the gas meter body 10 through the inlet 12,
During this time, the rotation of the valve in the gas meter 10 is transmitted to the pinion 13, and the rotation of the pinion 13 is transmitted to the counter section 20 via the reduction gear group 14, The counter section 20 displays the cumulative amount of gas used. Therefore, in the gas meter as described above,
It has been proposed to provide a pilot display device to determine whether or not the gas meter is operating, and in the illustrated example, a gear in the middle of a group of reduction gears is It is displayed externally so that the rotation of the gear can be visually observed. However, when the rotation of the reduction gear is visually observed as in the prior art described above, the movement of the outer peripheral part (part A) of the detection gear is determined by the gas flow rate 5.
/h, it is extremely small at around 2.5mm/min, and when used as a pilot light for gas appliances (4 to 5/h), it is difficult to quickly and accurately determine whether the gas meter is operating or not. I couldn't do it. Also,
There was a problem in that if the rotation of the detection gear serving as the pilot display device was inhibited, the rotation of the valve was also inhibited.

0 is a diagram for explaining an example, FIG. 7 is a plan view, FIG. 8 is a front view, and FIG. 9 is a cross-sectional view taken along the line -- in FIG. 42 is a transparent acrylic base, 43 is a polyacetal magnet stand, 44 is an amyl plate dial, 45 is a stainless steel plate protective cover, 46a,
46b indicates a magnet. This pilot indicator 40
After assembling the two magnets 46a, 46b and the dial 44 to the magnet stand 43, they are assembled into the base 42 and the cover 41 and welded (see part a), and the antifreeze 47 is sealed inside. , cover with the protective cover 45 and assemble. Therefore, as is clear from the figure, the dial, which is the second rotating body, is made visible from the outside and is sealed. On the other hand, the gas meter main body 10 is provided with an arm 19 above a worm 16 that rotates at the same rotation speed as the valve 15.
Two magnets 18a and 18b are bonded to 9. In the present invention, the gas meter main body 10 and the pilot indicator 40 are constructed as described above, and the pilot indicator 40 is attached to the upper part of the upper case of the gas meter main body 10 in alignment with the center of rotation of the worm 16. Therefore, the rotation of the worm 16 is transmitted to the magnet stand 43 of the pilot display 40 by the action of the magnets 18a, 18b, 46a, and 46b, and the dial 44 integrally attached to the magnet stand 43 rotates. Therefore, the rotation of the valve inside the gas meter can be confirmed from outside the meter. According to the present invention, the outer peripheral speed of the dial 44 is 10.2 when the gas flow rate is 5/h.
mm/min, which is approximately 4 times the movement of a conventional pilot display. Therefore, the operating status of the gas meter can be confirmed more quickly and reliably than with conventional gas meters. Furthermore, if the cover 41 is shaped like a lens as shown in the figure, the dial 44 can be enlarged and displayed, and the slight movement of the dial can therefore be confirmed in a shorter time.

る。 As is clear from the above description, according to the present invention, it is possible to quickly and reliably determine the operating state of the gas meter at the time of a minute flow rate, and the rotation of the second rotating body in the display device is inhibited. However, the influence on the rotation of the first rotating body is small. Furthermore, by sealing the antifreeze inside the display device, the rotation of the second rotating body is prevented from being inhibited, and the rotation of the first rotating body is transmitted to the second rotating body by magnetic force. Even if the rotation of the second rotating body is inhibited, the rotation of the first rotating body that converts the motion of the gas can be prevented from being inhibited.
