動により運転者に警告するものである。 To explain a general speed warning device with reference to FIG. 7, reference numeral 1 indicates an eddy current type speedometer installed in a vehicle, and a rotating shaft that is driven to rotate in proportion to the vehicle speed is attached to a conductive frame 2 of the speedometer 1. 3 is pivotally mounted, and this rotating shaft 3
A magnet 4 is fixed to the upper end, and a guide plate 6 is arranged fixed to the pointer shaft 5 with a small gap between the magnet 4 and the pointer shaft 5. A pointer 7 is fixed to the upper end of the pointer shaft 5. Further, one end of a hair spring 8 is fixed to the pointer shaft 5, and the other end is fixed to the machine frame 2 side. When the rotary shaft 3 is driven to rotate in proportion to the vehicle speed, the rotation of the magnet 4 causes the guide plate 6 to vortex. A current is generated, and a rotational torque proportional to the rotation speed of the rotating shaft 3 is obtained on the guide plate 6, and the pointer shaft 5 rotates together with the guide plate 6 to a position where the rotational torque and the elasticity of the hair spring 8 are balanced, and the pointer rotates. The running speed of the vehicle is measured by reading the indicated value 7 in comparison with the indicated scale (not shown) on the dial plate 9. Further, an alarm speed setting plate 10 having an arcuate protrusion 10a centered on the pointer shaft 5 is disposed on the side of the pointer shaft which is angularly displaced in proportion to the rotational speed of the rotating shaft 3. Contact elastic piece 1 that comes into contact with the arcuate protrusion 10a of
1 is fixed to the conductive machine frame 2 via an insulating member 12. A warning speed range is set by the angular width of the arcuate protrusion 10a. Further, an alarm circuit is formed by the battery 13, the elastic contact piece 11, the machine frame 2, and an alarm indicator 14 such as a buzzer or lamp. When the rotating shaft 3 rotates in proportion to the vehicle speed, the rotation of the magnet 4 causes the pointer 7 to follow along with the guide plate 6 to a position commensurate with the vehicle speed, thereby indicating the traveling speed. At this time, when the vehicle speed reaches a predetermined alarm speed or higher, the contact elastic piece 11 contacts the arcuate protrusion 10a of the alarm speed setting plate 10 and becomes electrically conductive, closing the alarm circuit and activating the alarm indicator 14. This is to warn the driver.

The three parts are stacked one on top of the other and fixed to the machine frame 2 with screws 15. Therefore, it is troublesome to overlay one insulating piece 12a, the contact elastic piece 11, and the other insulating piece 12b and fasten them with screws, and the assembling process is time-consuming and requires a pair of insulating pieces 12a and 12b. There was also a problem in terms of cost.

When the rotary shaft 23 is driven to rotate in proportion to the vehicle speed, an eddy current is generated in the guide plate 26 due to the rotation of the magnet 24, and a rotational torque proportional to the rotation speed of the rotary shaft 23 is obtained in the guide plate 26. 26, the pointer shaft 25 rotates to a position where the rotational torque and the elasticity of the hair spring 28 are balanced, and the running speed of the vehicle is measured by comparing and reading the indicated value of the pointer 27 with the indicated scale of the dial 29.

A cam 37 is formed on the transmission shaft 36, and a swinging piece 38 formed integrally with the contact elastic piece 31 is in resilient contact with the cam 37. When the rotating shaft 23 rotates in proportion to the vehicle speed, the rotation of the magnet 24 causes the pointer 27 to follow along with the guide plate 26 to a position commensurate with the vehicle speed, thereby indicating the traveling speed. At this time, when the vehicle speed reaches a predetermined alarm speed or higher, the contact elastic piece 31 contacts the arcuate protrusion 30a of the alarm speed setting plate 30 and conducts, closing the alarm circuit and activating the alarm indicator 34. In this case, the first and second transmission shafts 35 and 36, which are sequentially branched and transmitted from the rotating shaft 23, are also rotated, and the cam 37 formed on the second transmission shaft 36 is also rotated. Rocking piece 38 in elastic contact with 37
The cam 37 swings corresponding to the difference in height between the top dead center and the bottom dead center, and the contact elastic piece 31 formed integrally with the swing piece 38 also moves toward the arcuate protrusion 30a. It swings and comes into contact with the arcuate protrusion 30a intermittently. Therefore, the alarm display 34 will issue an alarm intermittently.

枠22との当接部43が突出形成している。 Therefore, the contact elastic piece 31 and the terminal piece 31a are positioned on the clamping piece 32a by the positioning part 39, and the clamping piece 32c, which is integrally formed with the clamping piece 32a, is bent from the hinge part 32b and overlapped. By engaging the engaging portion 32d of the clamping piece 32a and the clamping piece 32c, the contact elastic piece 31 and the terminal piece 31a are clamped, and in this state, the contact elastic piece 31 and the terminal piece are held together via the insulating member 32. 31a are fixed with screws 42. In this case, a clamping piece 32c is arranged on the machine frame 22 side, and a contact portion 43 with the machine frame 22 is formed protruding from the surface of the clamping piece 32c on the machine frame 22 side.

果は大きい。 As described above, the present invention pivots the rotating shaft that transmits the rotational driving force of the vehicle to the conductive frame of the instrument, and the pointer shaft is attached to the pointer shaft side that angularly displaces in proportion to the rotational speed of the rotating shaft. A conductive alarm speed setting plate having an arc-shaped protrusion at the center is provided, and an elastic contact piece that contacts the alarm speed setting plate is fixed to the conductive machine frame side via an insulating member. The insulating member is formed of a pair of clamping pieces connected by a hinge part, a positioning part is formed on at least one of the clamping pieces, the contact elastic piece is interposed between the pair of clamping pieces, and Since the contact elastic piece is positioned and regulated by the positioning part, the work of clamping the contact elastic piece and assembling it to the machine frame is simple, and the cost can be reduced, which is highly effective.
