The tip end side protruding to the inner surface of the container 24 contacts the lower surface of the insulating member 60 and pushes the other end of the adjusting plate 48 upward through the insulating member 60. By adjusting the screwing amount of the adjusting screw 64 into the container 24, the distance between the other end of the adjusting plate 48 and the container 24 can be varied, and the distance B between the upper surface of the leaf spring 54 and the lower end surface of the armature 42 can be changed. Can be changed. When the distance B between the leaf spring 54 and the lower end surface of the armature 42 is changed, the electromagnetic coil 12 is excited and the armature 42 is attracted, and then the armature 42 contacts the leaf spring 54 and pushes the leaf spring 54 downward. Since the time required to move the movable contact 52 and disconnect the movable contact 52 from the fixed contact 50 is changed, the amount of current flowing through the electromagnetic coil 12 changes and the sound pressure level of the electric horn 10 can be changed.

The adjusting screw 64 is required to prevent it from easily turning even if an external force is applied after the electric horn is assembled and the sound pressure level thereof is adjusted. For this reason, a screwing agent made of synthetic resin is applied between the female screw hole 62 and the adjusting screw 64, or a nut for preventing rotation is screwed into the adjusting screw 64 to adjust the sound pressure level. It is necessary to tighten the nut so that it comes into contact with the container 24 and suppress the rotation of the adjusting screw 64, which is troublesome.

を鳴動させる。In the operation of the interrupter 22, when the fixed contact 50 and the movable contact 52 are in contact with each other and are electrically connected, a current is passed through the electromagnetic coil 12 to excite the electromagnetic coil 12. Next, the armature 42 attracted inside the bobbin 18 by the excited electromagnetic coil 12.
The lower surface of the large-diameter column portion 46 of the
Is moved toward the electromagnetic coil 12 side to separate the movable contact 52 from the fixed contact 50, the power supply to the electromagnetic coil 12 is stopped. Next, when the excitation of the electromagnetic coil 12 is released,
The armature 42 returns to its original position again due to the elastic force of the vibration plate 36, and the pushing motion of the plate spring 54 is released, so that the fixed contact 50 and the movable contact 52 contact again and the electromagnetic coil 1

できるのである。The sound pressure level of the electric horn 10 can be varied as described in the conventional example by adjusting the screwing amount of the adjusting screw 64 into the container 24. That is, as shown in FIG. 3, when the distance between the other end of the adjusting plate 48 and the container 24 is changed by the adjusting screw 64, the distance B between the upper surface of the leaf spring 54 and the lower end surface of the large diameter column portion 46 of the armature 42 is changed. Yes, this leaf spring 54 and armature 4
When the distance B from the lower end surface of 2 is varied, the electromagnetic coil 12 is excited and the armature 42 is attracted, and then the armature 42 contacts the leaf spring 54 and pushes the leaf spring 54 downward to move the movable contact 52. Since the time required to disconnect from the fixed contact 50 is changed, the amount of current flowing through the electromagnetic coil 12 changes, and the sound pressure level of the electric horn 10 can be changed.

されるのである。After adjusting the screwing amount of the adjusting screw 64, in order to prevent the sound pressure level from changing as described in the conventional example, the adjusting screw 64 is prevented from easily turning even if an external force is applied. Although necessary, in the present invention, an insulating member 60 extending between the other end of the adjusting plate 48 and the container 24 as shown in FIG. 4 is used without using a conventional resin screw fastening agent or nut. A through hole 74 having a diameter smaller than that of the adjusting screw 64 is formed in a portion corresponding to the other end of the adjusting plate 48 at the other end, and the female screw hole 62 provided in the container 24 is provided at a position corresponding to the through hole 74. It's different. With this configuration, the adjustment screw 6
When 4 is screwed into the female screw hole 62 from the outer surface of the container 24, the distal end side of the adjusting screw 64 protruding to the inner surface of the container 24 is inserted into the through hole 74 and the through hole 74 is formed against the elastic force of the insulating member 60. It is screwed while expanding the diameter, penetrates the insulating member 60, contacts the other end of the adjusting plate 48, and pushes the adjusting plate 48. The adjusting screw 64, which has been screwed into the through hole 74 of the insulating member 60, is subjected to a tightening force by the elastic force of the insulating member 60 from the inner peripheral surface of the through hole 74, so that the rotation is suppressed. .

しても良い。In the above-described embodiment, since the insulating plate 58 is arranged at the contact portion of the plate spring 54 with the armature 42, the gap between the armature 42 and the plate spring 54 pushed by the armature 42 is provided. The current path between the power source, the electromagnetic coil 12 and the interrupter 22 is insulated, and the electrode from one electrode of the power source is from the container 24 to the rivet 56 (or the adjusting screw 64) to the adjusting plate 48 to the fixed contact 50, and to the power source. The other electrode is connected from the electromagnetic coil 12 to the leaf spring 54 to the movable contact 52. Therefore, when the fixed contact 50 and the movable contact 52 come into contact with each other, a current flows through the electromagnetic coil 12,
Excited. In addition, instead of this structure, the armature 42
An insulating plate may be arranged on the lower end surface of the large-diameter column portion 46. Further, the adjusting screw 64 directly contacts the adjusting plate 48 and pushes the other end of the adjusting plate 48. However, when it is desired to ensure insulation between the adjusting screw 64 and the adjusting plate 48, for example, When the power source, the electromagnetic coil 12, and the interrupter 22 are insulated from the container 24, a tongue piece portion 76 is extended to the other end of the insulating member 60 as shown in FIGS. Bend the tongue piece 76 as shown in FIG.
It may be inserted between the tip of the and the lower surface of the other end of the adjusting plate 48.

効を奏する。When the electric horn according to the present invention is used,
Since the adjusting screw is screwed into the through hole provided in the insulating member made of synthetic resin, rotation is prevented by the tightening force from the inner peripheral surface of the through hole which is about to be reduced in diameter. Therefore, unlike the conventional case, it is not necessary to use a screwing agent or a fixing nut, the number of parts can be reduced and the fixing work can be simplified, and the cost and the working time can be shortened.
