Reference numeral 20 is a speedometer using a crossed coil type movable magnet type instrument, and this speedometer 20 has a movable magnet 20B disposed inside a bobbin body 20A which is divided into two halves made of upper and lower synthetic resin materials. A pointer shaft, which will be described later, is press-fitted into 20B, and a coil 20C is wound around the outer periphery of the bobbin body 20A in a crossing manner. Further, a mounting base 21 is provided at the lower end of the bobbin body 20A to protrude outward, and a metal magnetic shielding cover 23 for the speedometer 20 is provided in an opening 22 bored in the center of the base portion 11A of the frame body 11. while inserting and arranging the upper part of the mounting base 2.
A frame body 11 is placed on the frame body 1, and the mounting base 21 is fixed to the mounting portion 24 of the frame body 11 with screws 25, so that the speedometer 20 is fixed to the frame body 11.

A frame-shaped connecting part 26 is formed in the frame body 11 between the counters 12 and 13 at the upper part of the opening 22, and the lower part thereof is curved and expanded in accordance with the outer periphery of the counters 1213. However, this lower end is connected to the base portion 11A.

A mounting seat 29 on which a display board 28 is mounted is protruded from the upper surface 27 of the connecting part 26, and the mounting seat 29 is inserted through a through hole 30 that is not drilled in the display board 28. The display board 28 is fixed to the frame body 11 by screwing screws 32 into the holes 31. Further, a hole 34 through which the pointer shaft 33 of the speedometer 20 is inserted is bored in the upper surface 27 of the connecting portion 26, and the pointer shaft 33 is inserted through this hole 34 and the hole 35 of the display plate 28.
A pointer 36 is fixed to the tip of the pointer 36, and the amount to be measured is indicated and displayed by comparing the pointer 36 with a display section (not shown) of the display board 28.

Further, a gear box 37 located in the center of both the counters 12 and 13 and housing a step motor (not shown) is attached and fixed to one side of the frame body 11 with screws 38. 39
The rotation is transmitted to each of the counters 12 and 13.

Further, a mounting leg portion 40 is provided on the frame body 11 so as to protrude downward from the lower surface of the base portion 11A. The frame body 11 is fixed onto the circuit board 41 by screwing the frame body 11 onto the circuit board 41.
