Next, we will explain how to assemble this lever-equipped variable resistor.

As shown in FIG. 1, first, the first shaft member 13 is inserted into the box-shaped case 11 from the bottom side. At this time, the shaft portion 137 of the first shaft member 13 is inserted into the shaft support holes 115, 115 formed in the opposite side walls of the box-shaped case 11.

Next, the flat plate portion 123 of the operating lever 12 is inserted into the long hole 143 of the second shaft member 14, and the pin 148 is inserted into the small hole 149 of the second shaft member 14 and the hole 125 of the operating lever 12. As a result, the operating lever 12 is rotatably supported on the second shaft member 14. The upper side of the operating lever 12 is connected to the elongated hole 133 of the first shaft member 13 and the hole 111 of the box-shaped case 11.
At the same time, the shaft portion 145 of the second shaft member 14 is inserted into the shaft support hole 115 formed in the opposite side walls on the side where the first shaft member 13 is not attached.

Then, the push-up member 16 and the coil spring 17 are pushed into the box-shaped case 11 from the back side of the second shaft member 14.
After that, insert the bottom plate 18 into the box-shaped case 11.
It is fixed to the back surface of the holder with an engaging claw 18a. At this time, the upper side of the coil spring 17 is fixed by the spring receiving part 167 (see FIG. 3) of the push-up member 16, and the lower side thereof is fixed by the spring receiving part 18c of the bottom plate 18.

On the other hand, the substrate 151 is attached to one side wall 11a of the box-shaped case 11 by a guide protrusion 113 formed on the side wall 11a. At this time, the first
The locking pawl 139 of the shaft member 13 protrudes from the circular hole 151c. Then, this locking claw 139 is attached to the sliding body 1.
53 into the hole 153c. As a result, the slider 153b of the slider 153 is pressed onto the resistor pattern 151a of the substrate 151, and the first shaft member 1
3 rotates, the slider 153 also rotates, the slider 153b slides on the resistor pattern 151a, and the resistance value between the metal terminals 151b changes.

Next, the operation of this lever-equipped variable resistor will be explained.

FIG. 6 is a diagram showing the internal structure of this lever-equipped variable resistor when operated.

Figure a is a diagram showing the internal structure when the operating lever 12 shown in Figure 4 is tilted in the direction A from the neutral position (a diagram when cut in the direction of line C-C shown in Figure 5).
It is. As shown in the figure, the operating lever 12 is
When the first shaft member 13 is tilted in this direction, the first shaft member 13 is tilted about the pin 148. As a result, the first shaft member 1
3 rotates, and the resistance value of the rotary electronic component 15 changes. Also, at this time, as the first shaft member 13 rotates, the tilted projection 136 of the projections 136, 136 attached to the first shaft member 13 pushes the abutment base 161 of the push-up member 16 against the coil spring. 17
Press downward against the elastic force of. As a result, the push-up member 16 is moved to the spring receiving portion 18 of the bottom plate 18.
It moves downward guided by the outer periphery of c.

When the user releases the operating lever 12, the push-up member 16 is pushed up by the elastic force of the coil spring 17, and the operating lever 12 remains stationary facing vertically upward.

Figure b is a view showing the internal structure when the operating lever 12 shown in Figure 4 is tilted from the neutral position in the direction B (a view taken when cut in the direction of line D-D shown in Figure 5).
It is. As shown in the figure, move the operating lever 12 to B.
When the second shaft member 14 is tilted in this direction, the second shaft member 14 is tilted around the center of the pin 148. As a result, the sliding body 153' of the rotary electronic component 15' attached to the second shaft member 14 rotates, and the resistance value of the rotary electronic component 15' changes. Also, at this time, among the protrusions 146, 146 attached to the second shaft member 14 by the rotation of the second shaft member 14, the protrusion 1 on the inclined side
46 presses the abutment base 163 of the push-up member 16 downward against the elastic force of the coil spring 17. As a result, the push-up member 16 is guided by the outer periphery of the spring receiving portion 18c of the bottom plate 18 and moves downward.

When the user releases the operating lever 12, the push-up member 16 is pushed up by the elastic force of the coil spring 17, and the operating lever 12 remains stationary facing vertically upward.

In addition, in the above operation explanation, in order to make the explanation easier to understand, the case where the operation lever 12 is tilted in the A direction and the B direction is explained as an example, but the operation lever 1
2 may be tilted in any direction other than the A direction and the B direction. In this case, the first shaft member 13 and the second shaft member 14 will both rotate, but the push-up member 16 will be moved by the protrusion 13 on the side that rotates to a greater extent.
6 or the protrusion 146.

Although one embodiment of the electronic component with a lever according to the present invention has been described in detail above, the present invention is not limited to this and various modifications are possible. For example, the rotary electronic components 15, 15' 1st each
It may be attached to both ends of the shaft member 13 and the second shaft member 14. It goes without saying that the present invention is not limited to rotary variable resistors, but can be applied to other rotary electronic components such as rotary switches.

That is, the point is that the first shaft member 13 and the second shaft member 1
4 are perpendicular to each other and rotatably supported in the case, and when either or both of the first shaft member 13 and the second shaft member 14 are rotated by an operating lever, the first shaft A push-up member 16 that is pushed down by the member 13 or the second shaft member 14 is arranged below both shaft members, and a resilient member that pushes up the push-up member 16 upward is arranged below the push-up member 16. Any electronic component with a lever configured to do so may be used.
