づらせて連結させた。E is a noggles motor that counts the number of pulses corresponding to the vehicle speed at regular time intervals, distinguishes the difference between the current count value and the previous count value as positive or negative, and rotates the clock in the positive or reverse direction using an output pulse equal to the difference. This shows the speed needle that is moved by the pulse motor (1), FiA roller (2), K worm (3), and a reduction mechanism (5) consisting of a worm gear (4).
The speed reduction mechanism (5) and the pointer shaft (7) of the pointer (6) are provided.
The skeleton pointer shaft (7) is connected via a spiral spring (the lower end of the force is - le aυ
It is supported upright via the outer periphery of the skeleton pointer shaft (7). and the worm gear (4)
is formed into a split gear (4m) (4b) that is split at the center of meshing with the worm (3), and the split gear (4aH4b)
) are supported on the outer peripheral surface of the cylindrical body 01, and are connected in a phase-shifted manner via a torsion spring I housed in a recess formed in the bearing surface.

ラッシュは消去される。Therefore, warm ear (4) is M3 for warm ear (3).
As shown in the figure, one split gear (4a) is a worm (3
) is always in elastic contact with the front surface of the tooth surface of the worm (3) by the elastic force of the spring (to), and the other split gear (4b) is always in elastic contact with the rear surface of the tooth surface of the worm (3) by the elastic force of the spring. The worm (3) and the worm gear (4) are brought into contact with each other, thus eliminating the notch clash between the worm (3) and the worm gear (4).

なる等の効果を有する。In this way, according to the present invention, the worm gear in the reduction mechanism consisting of the worm and the worm gear provided on the rotating shaft of the pulse motor is shaped into 1111 gears divided at the meshing center of the worm, and the crease division gear is Since they are connected through screw springs with their phases shifted, backlash between the worm and worm gear can be completely eliminated and accurate pointer display can be performed. Since it can be attached to a container, it has the effect that the instrument assembly becomes a container.
