8f. The click arm 8
In FIG. 9A, as shown in FIG. 9, a bending line 8j is formed at a connection portion of the root portion with the connecting portion 8f, and the bending portion 8b is bent obliquely downward from the bending line 8j. A slit 8c is formed between the click arm 8a and the base 8d, and an oval shaft hole 8e is formed at the center of the base 8d at a position sandwiching the slit 8c. Shaft hole 8e
Is press-fitted and attached to a slot dropping portion 1d of the operation shaft 1. At the center of the arc-shaped tip of the click arm 8a, a convex portion 8b whose thickness is reduced by drawing is formed so as to protrude downward on the end side. The convex portion 8b engages with the valley portion 2d of the concave portion 2b of the bearing 2 so that a click feeling can be obtained on the operation shaft 1. As described above, the reason why the drawing process is performed by protruding the projection 8b is that the two portions between the projection 8b and the connecting portion 8f located on both sides of the projection 8b are twisted, deformed, etc. The protrusion 8b is normally engaged and disengaged from the protruding portion 2c and the valley portion 2d while maintaining the punched state without causing the occurrence of the protrusion. Also, the insulating substrate 4,
On one side of 4 ', there are arranged terminals 10 for leading out a resistance value or the like which changes by rotation of the slider 7 to the outside. In addition, the flange 1b of the operation shaft 1 and the boss 2e of the bearing 2
A wave-shaped spring washer 1 having a shaft hole 11a made of a phosphor bronze strip or the like as shown in FIG.
Holding one. Then, when the operation shaft 1 is rotated,
The wavy spring washer 11 is used for the flange 1 of the operation shaft 1.
Friction occurs between the shaft b and the bearing 2, and a predetermined rotational torque can be obtained on the operation shaft 1 by the frictional resistance.

[0005] In assembling the conventional rotary electronic component having the above-described configuration, the knob 1a of the operation shaft 1 is held by an assembly jig (not shown), and the operation shaft 1 is mounted upright. Then, a spring washer 11 is inserted from the tip of the slot dropping portion 1d of the operation shaft 1 and positioned on the flange portion 1b. next,
The shaft hole 2a of the bearing 2 is inserted from the tip of the slot 1d of the operating shaft 1 so that the bearing 2 is fitted to the fitting portion 1c of the operating shaft 1. Next, the oval-shaped shaft hole 8e of the leaf spring 8 is aligned with the slot drop portion 1d of the operation shaft 1, and the leaf spring 8 is press-fitted until the assembly jig hits the annular ridge 2f of the bearing 2. I do. Then, the projection 8b of the click arm 8a of the leaf spring 8 is engaged with the valley 2d of the recess 2b of the bearing 2 as shown in FIG.

Next, the lower substrate 10 in FIG.
Then, the sliders 7, 7 'prepared in a separate process in advance
The shaft hole 6c of the slider holder 6 to which is attached is positioned and inserted into the slot dropping portion 1d of the operation shaft 1. Then, one end of the slider receiver 6 comes into contact with the base 8d of the leaf spring 8 which is pressed into the slot dropping portion 1d of the operation shaft 1.

Next, the slider holder 6 is pressed downward by the assembling jig, and a caulking punch (not shown) of the assembling jig is pressed.
Then, the tip of the sliding portion 1d of the operation shaft 1 is crimped with a hand press or the like. Then, the lower mounting leg (not shown) of the cover 5 is placed so as to be inserted into the mounting hole (not shown) of the lower substrate 10 and the bearing 2.
The upper substrate 10 is placed on the upper mounting leg (not shown) of the above, and the lower mounting leg of the cover 5 is caulked to the bearing 2 with a caulking jig different from the assembling jig, and the upper mounting is performed. The legs are swaged to the upper substrate 10, and the assembly of the conventional rotary electric component is completed.

[0008] When the operating shaft 1 is rotated, the conventional rotary electric component assembled according to the above-described procedure has a leaf spring 8.
The click portion 8b of the click arm 8a elastically moves to the protruding portion 2c and the valley portion 2d in the concave portion 2b of the bearing 2, so that a click feeling can be obtained on the operation shaft 1. Further, frictional resistance is generated between the flange 1b of the operation shaft 1 and the bearing 2 by the elastic force of the wave-shaped spring washer 11, so that a rotational torque can be obtained on the operation shaft 1.

[0009]

However, in the conventional rotary electric component as described above, the click projection 8b provided on the leaf spring 8 is drawn by projection, so that a strong click feeling is obtained. There is a problem that it is difficult to have a large protruding shape to obtain, and there is a restriction to obtain a strong click feeling. In addition, the size of the click leaf spring 8 is limited due to the reduction in the size of the rotary electric component, and the leaf spring 8 cannot be enlarged from this point.
There is a problem that there is a restriction to obtain a strong click feeling.

In addition, since the convex portion 8b is made thin by drawing, there is a problem that the click life is short. In addition, since the leaf spring 8 for obtaining a click feeling and the spring washer 11 for obtaining a rotational torque are separately provided, the number of parts is large, so that it takes time to assemble the conventional rotary electric parts. Cost was up.

Further, when the leaf spring 8 of the conventional rotary electric component is press-fitted into the oval-shaped slip-off portion 1d of the operation shaft 1 and fitted thereto, the fitting between the leaf spring 8 and the slip-off portion 1d is performed. Is too short to fit the base 8
There has been a problem that d is deformed and the mounting position of the slider receiver 6 is changed. In addition, there is a problem in that if it is attached with a play, a click feeling cannot be generated at a predetermined position.
