光ダイオードが設置されている。符号１０は発光
ダイオード取付用のブラケツトである。 A scale member 8 made of a luminous fiber is disposed behind the liquid volume tube 5, and a light emitting diode serving as a light source 9 is disposed at a position opposing the upper end surface of the scale member 8. There is. Reference numeral 10 is a bracket for mounting a light emitting diode.

前記目盛部材８の背面には、目盛状切欠１１，
１１…が等間隔で形成されている。 On the back surface of the scale member 8, there are scale-shaped notches 11,
11... are formed at equal intervals.

つまり、この目盛部材８は光源９からの光を伝
