And The decoration plate 1 has anti-vibration fixing parts 12 respectively fitted to the left and right brackets 3, and the lower half of the anti-vibration fixing parts 12 is provided between the bracket 3 and the instrument fixing member 5. Part is pinched. The edge 14 of the decoration plate 1 covers the outer edge of each bracket 3 and engages with the edge of the bracket 3.
The material of the decoration plate 1 is rubber for vibration isolation, and the decoration plate 1 is integrally formed.

[0015] Both anti-vibration fixing portions 1 of the decoration plate 1
2, a through hole 12 a is formed in the thickness direction in the central portion. A hexagon socket head bolt 6 is inserted into each through hole 12a from above in FIG. 2, and the bolt 6 is screwed into a screw hole 5a formed in the metal instrument fixing member 5. That is, the left and right brackets 3 are fixedly held on the instrument fixing member 5 via the vibration-proof fixing parts 12 by the bolts 6 penetrating through the through holes 12a of the left and right vibration-proof fixing parts 12, respectively.

At the center 13 of the cover 11 of the decoration plate 1, a ring-shaped groove 13a is formed on the back surface. The central portion 13 forms a positive quadratic surface slightly convex upward in FIG. 2, but can be deformed downwardly convex with the groove 13 a as a fulcrum when a pressing force is applied from the surface. . On the back side of the central part 13 of the cover part 11, a pressing switch 8 which is operated by a pressing operation due to this deformation is provided, and is fixed on the circuit board 9 by soldering. Here, when the pressing force from the surface is lost, the central portion 13 of the decoration plate 1 is naturally inverted again to return to the original shape.

As shown in FIG. 1 again, the meter assembly 4 includes a speedometer 4a, an engine tachometer 4b, and an electronic odometer and trip meter 4c having a display unit incorporated in the speedometer 4a.

Designed.

(Effects of the First Embodiment) The instrument mounting device of the present embodiment is constructed as described above, and exhibits the following two effects. First, the first effect is
This is a cost reduction effect. That is, in the instrument mounting device of the present embodiment, the decoration plate 1 has the anti-vibration fixing portions 12 fitted to the left and right brackets 3 holding the instrument assembly 4. Through hole 12a of anti-vibration fixing part 12
Since the bolt 6 is inserted and screwed into the instrument fixing member 5, the bracket 3 is held in a state where the anti-vibration fixing portion 12 is sandwiched between the instrument fixing member 5 and the bolt 6.
It is held by the instrument fixing member 5 and the bolt 6. Therefore, the rubber anti-vibration fixing part 12 sandwiched between the instrument fixing member 5 and the bolt 6 and the bracket 3 is used.
Due to the elastic deformation of the bracket 3, the bracket 3 is supported on the instrument fixing member 5 in a vibration-proof manner.

That is, when the bracket 3 supporting the instrument assembly 4 is fixed to the instrument fixing member 5, the anti-vibration fixing portion 12 of the decoration plate 1 is replaced with the conventional anti-vibration rubber 2.
(See FIG. 6). Therefore, the bracket 3 is firmly held by the instrument fixing member 5 via the anti-vibration fixing part 12 by the bolt 6 without the anti-vibration rubber 2, and there is no possibility of falling off.

Further, since the decoration plate 1 including the anti-vibration fixing portion 12 is integrally formed of rubber, the decoration plate 1 can be manufactured relatively inexpensively. Therefore, according to the instrument mounting apparatus of the present embodiment, the number of parts and the number of assembling steps are reduced without the need for the vibration isolating rubber, and the cost can be further reduced without impairing the vibration isolating support function. .

The second effect is an improvement in the appearance and reliability associated with the mounting of the switch. That is, in the instrument mounting device of the present embodiment, the cover 1
The central portion 13 of the device 1 can be deformed by a pressing force from the front surface, and a switch 8 that is operated by a pressing operation due to the deformation is provided on the back surface side of the central portion 13. Therefore, the switch 8 can be operated by pressing the central part 13 of the cover part 11 of the decoration plate 1 with the driver's finger or the like. The switch operation switches between the odometer display (total mileage) and the trip meter display with a short press, and the trip meter is reset to zero if it is kept pressed for more than a predetermined time in the state of the trip meter. I have.

Therefore, in arranging the switch 8,
There is no need to form a switch hole in the cover portion 11 of the decoration plate 1 or attach a waterproof cover to the switch 8. Further, since the switch buttons and the like are not exposed, the reliability of the switch 8 is high, the surface of the decoration plate 1 is kept smooth, and a favorable appearance can be obtained. Therefore, according to the instrument mounting device of the present embodiment, the switch 8 can be provided with high reliability without increasing the cost of the decoration plate 1 and without deteriorating the appearance.

Further, a modified embodiment in which the decoration plate 1 is integrally formed of soft plastic by injection molding or the like is also possible. According to this modification, the decoration plate 1
Can be selected in a variety of colors, so that the aesthetic appearance can be further improved. [Embodiment 2] (Main part configuration of Embodiment 2) An instrument mounting device as Embodiment 2 of the present invention includes an instrument assembly 4 'and a decoration plate 1' for a motorcycle as shown in FIG. Vibration-proof support for a top bridge (not shown), which is a fixing member on the side.

That is, the instrument mounting device of this embodiment is
A case 4k that holds the instrument assembly 4 'with the bracket portion 3' bolted to the left and right two bolt holes (not shown) of the top bridge with hexagon socket head bolts (not shown).
(See FIG. 4). Further, the instrument mounting device of this embodiment has a rubber decoration plate 1 'having a cover portion 11' covering most of the bracket portion 3 'of the case 4k.
It also has The material of the decoration plate 1 'is black rubber for vibration isolation, and the decoration plate 1' is a rubber cover integrally formed in a flat shape similar to a bat with wings spread. The surface of the decoration plate 1 'is formed with fine leather-like irregularities, and exhibits a unique aesthetic appearance together with a matte effect.

As in the first embodiment, the decoration plate 1 '
Are formed with two anti-vibration fixing portions 12 'fitted respectively to the left and right bracket portions 3'. The lower half (not shown) of the vibration-proof fixing part 12 ′ is sandwiched between the bracket part 3 ′ (see FIG. 4) of the case 4 k and the top bridge (instrument fixing member) on the vehicle side. I have. The left and right edges 14 'of the decoration plate 1' cover the outer edges of the left and right bracket portions 3 ', respectively, and the front side of the decoration plate 1' is the front half of a top bridge (not shown) on the vehicle side. Is covered.

The gap between the top bridge (not shown) on the vehicle side and the decoration plate 1 'is about 2 mm.
Therefore, the front side of the decoration plate 1 ′ comes into contact with the top bridge due to the impact the motorcycle receives while traveling,
Since the decoration plate 1 'has rubber elasticity, the decoration plate 1' is not damaged. Conversely, since the decoration plate 1 'has rubber elasticity, the gap with the top bridge can be suppressed to only 2 mm, and the appearance can be improved.

Through holes 12a 'are formed in the thickness direction at the center of the vibration isolating fixing portions 12', two on each of the right and left sides of the decoration plate 1 '. As in the first embodiment, a hexagon socket head bolt (not shown) is inserted into each through hole 12a 'from above, and the bolt is screwed into a screw hole formed in a steel top bridge (not shown). Fixed. That is, in the case of the present embodiment, the meter assembly 4 ′ and the decoration plate 1 1 'is supported for vibration isolation.

In the center of the cover portion 11 'of the decoration plate 1', a key cylinder hole 15 to which the top of an ignition key key cylinder (not shown) fixed to the vehicle top bridge should project slightly. Is open. The gap between the inner peripheral surface of the key cylinder hole 15 and the outer peripheral surface of the key cylinder is about 1 mm. However, even if the key cylinder hole 15 and the key cylinder come into contact with each other due to impact, the decoration plate 1 ′ has rubber elasticity. No damage. Conversely, since the decoration plate 1 'has rubber elasticity, the gap with the key cylinder is only 1 mm.
And the appearance can be improved.

At the upper central portion 13 'of the cover portion 11 of the decoration plate 1, a groove 13a' is formed in an inverted triangular shape on the surface, and when a pressing force is applied from the surface, the groove 13a 'is formed.
Is deformed, and the central upper portion 13 'can be displaced downward. As shown in FIG. 4, the central portion 1 of the cover portion 11 '
On the back side of 3 ', a pressing switch 8' that is operated via the pressing members 81 and 82 by the pressing operation due to this deformation is provided, and is fixed on the circuit board 9 'by soldering. Here, the central portion 13 'of the decoration plate 1'
When the pressing force from the surface is removed, the shape naturally returns to the original shape.

Note that turn signal lamps 16 are provided on the left and right of the key cylinder hole 15 of the decoration plate 1 '. (Instrument Aggregation of Second Embodiment)
As shown in FIG. 2, the speedometer 4a and the engine speed meter 4b are roughly divided. Speedometer 4a and engine tachometer 4
b is connected to and fixed to each other by a hood 4d also serving as a center connecting member.

The display unit of the electronic odometer and trip meter 4c is incorporated in the speedometer 4a on the front side. The control circuit of the electronic odometer and trip meter 4c is formed on a circuit board 9 '(see FIG. 4), and the display of the odometer and the display of the trip meter are switched by operating the push switch 8' (see FIG. 5). It is designed to be.
If the push switch 8 'is pressed for about 3 seconds while the trip meter remains displayed, the trip meter is reset to zero.

On the front side of the engine tachometer 4b, there is provided a warning light plate 4e made of a transparent synthetic resin having a chrome-plated surface and a metallic luster. Warning light plate 4e
Is formed integrally with the indicator plate of the tachometer 4b, and the back surface is painted black except for three circular warning light portions 4f which are half mirrors. As shown in FIG.
Behind the three circular warning light portions, LEDs 4p fixed to the circuit board 9 'are arranged.
Therefore, the warning light plate 4e normally has a metallic luster and looks as if it were made of metal.
At the time of p lighting, the lighting of the warning light 4p is visually recognized through the half mirror 4f, so that it is possible to appeal to the driver's sensitivity with a surprising effect.

Here, an LED is used for the warning light 4p, but the LED generally has much better responsiveness than a light bulb. Therefore, when a signal is input momentarily (for example, when shifting the transmission of the motorcycle from the first to the second, it passes through the neutral position for a moment), the LED may be lit only momentarily, which may be annoying. Therefore, it is preferable to provide a delay circuit for the LED for the neutral warning light so that the LED is not turned on by an instantaneous signal. In the present embodiment, the same LE is used to form a delay circuit.
A capacitor is connected in parallel to D.

The circuit board 9 'is provided with a lamp 4n for illuminating the instrument, in addition to the warning light 4p, so that illumination can be performed from behind the indicating board. A movement 4m for rotating the pointer is fixed to the center of the circuit board 9 '. The plurality of screws 91 fixing the movement 4m to the circuit board 9 'also have the function of connecting the printed wiring of the circuit board 9' and the circuit of the movement 4m.

The circuit board 9 'is fixed to a case 4k including a bracket 3', as shown in FIGS. The outer periphery of the case 4k is covered with a hood 4d also serving as a connecting portion. As shown in FIG. 4, the front side of the instrument indicator is covered with a cover glass 4g made of plexiglass (transparent acrylic resin) to be waterproof. The cover glass 4g has its entire periphery sandwiched by a case 4k, and is covered with a ring member 4h made of chromium-plated synthetic resin having a metallic luster on the outside thereof. 4g does not come off. The cover glass 4g is attached to the vehicle 30 ° upward from the vertical.

It is to be noted that the circuit on the vehicle side and the circuit of the instrument assembly 4 'are, as shown in FIG.
The connector C from the vehicle side is inserted into the socket 10 protruding from k and connected. (Lower Cover of Embodiment 2) As shown in FIG.
The circuit board 9 'and the like are covered with a semi-spindle-shaped lower cover 41 that is joined to the circuit board k.
Drainage holes 4i and 4j whose shapes are devised so that water does not enter from the outside are formed at the lowermost part of the lower cover 4l. Although FIG. 4 is a sectional view of the tachometer 4b, the drain holes 4i and 4j are the same on the speedometer 4a side.

The drain hole 4i is provided with a boss 4ib at the center of the hole. Even when water enters from the periphery of the boss 4ib during car washing or the like, the back of the drain direction is sealed. Therefore, even when water can be written directly into the drain hole 4i with a hose or the like, the water droplets do not scatter in the direct intrusion direction, and the water droplets whose momentum has been reduced leak out in the left and right directions. . In addition, since the scattering prevention walls 4ia each having a shape obtained by halving the pipe are provided on the left and right sides of the drain hole 4i, the water droplets that have entered completely lose their momentum on the inner wall surfaces of the scattering prevention walls 4ia, and the lower cover 4l Does not scatter.

The drain hole 4j has an outer wall surface formed of a small flat surface so that water does not easily enter the drain hole 4j, and a boss 4jb is provided at the center of the hole. , The back of the hole in the intrusion direction is sealed, and the opening is only in the left-right direction. Therefore, even when water can be written directly into the drain hole 4j with a hose or the like, water droplets do not scatter in the direct intrusion direction, and the water droplets whose momentum has been reduced only slightly leak in the left and right directions. . Of course, the water slightly entering the inside is immediately discharged from the drain holes 4i and 4j.

Further, as shown in FIG.
The embankment 4q is formed in the shape of an eight on the left and right from the center of the inner wall surface. Due to the action of the embankment 4q, even when dew is formed inside the lower cover 4l, the water drops do not wet the circuit board 9 'and the drain holes 4 of the speedometer 4a and the tachometer 4b.
i, 4j. Therefore,
Not only during rainfall but also when water is intense, such as when washing a car, or when dew condensation occurs, there is almost no infiltration of water into the lower cover 4l. Is discharged. therefore,
The circuit board 9 'is completely protected from flooding, and its reliability is not impaired by flooding except in extreme cases such as submersion.

(Effects of the Second Embodiment) Since the instrument mounting device of the second embodiment is configured as described above, the same cost reduction and high reliability as those of the first embodiment can be obtained. Can be. In the present embodiment, the warning light plate 4e of metallic luster shines, and an unexpected aesthetic effect is obtained. In addition, the intrusion of water is prevented by devising the shape of the drain holes 4i and 4j of the lower cover 4l. The effect of high reliability is also exhibited. Further, in the present embodiment, since the gap between the key cylinder and the top bridge on the vehicle side and the decoration plate 1 'is small, an effect of further improving the aesthetic appearance also occurs.
