A rotating body 35 to which a slider 34 is attached is attached to the non-circular portion 33a of the operation shaft 33. The rotation of the operation shaft 33 causes the slider 34 to slide on a resistor 37 attached to an insulating substrate 36. The rotary electric component D is operated by changing the resistance value.

As shown in FIG. 29, a click spring plate 38 made of a metal plate includes a base 38b having a non-circular hole 38a and an arm 3 extending from the base 38b in a semicircular shape.
8c and one convex portion 3 provided at the center of the arm portion 38c.
The spring plate 38 is attached to the operation shaft 33 by inserting the non-circular portion 33a of the operation shaft 33 into the non-circular hole 38a, and when the operation shaft 33 rotates, the convex portion 38d has a bearing. The click mechanism K is configured to be disengaged from the concave / convex portion 31 of the portion 32 and give a click feeling to the rotation operation. At this time,
Since only the convex portion 38 d of the spring plate 38 is pressed against the bearing portion 32, the rotation center axis is inclined when the operation shaft 33 rotates, so that smooth rotation cannot be performed.

In general, a rotary electric component with a click includes various operating forces for rotating the rotary electric component D, various click forces in the click mechanism K, and a predetermined rotational position of the operation shaft 33. Various click angles are required. Therefore, in the above-mentioned rotary electric component with a click, various operating forces are obtained by changing the thickness of the spring plate 38. Convex part 38 to 31
The degree of drop of d, that is, the size of the convex portion 38d is changed, and further, various click angles are obtained by changing the interval between the concave and convex portions 31 of the bearing portion 32. .

In this case, only the bearings 32 having different intervals between the concave and convex portions 31 need to be prepared without changing the spring plate 38. On the other hand, in response to various operating forces and various click forces, a large number of springs are required. A plate 38 needs to be prepared. For example, in order to respond to the first to third actuation forces and the first to third click forces, the size of each of the protrusions 38d in the spring plate 38 having the plate thickness of the first actuation force is set. Three click spring plates 3 having different first to third click forces

The click member 47 is spline-coupled by inserting the non-circular portion 43a of the operation shaft 43 into the non-circular hole 47a. While being rotated by the operation shaft 43, a coil spring 48 interposed between the click member 47 and the rotating body 45 and inserted and attached to the operation shaft 43 presses the click member 47 against the bearing portion 42, and the uneven portion 47 b Is engaged with and disengaged from the uneven portion 41 of the bearing portion 42.

When the operating shaft 43 is rotated, the click member 47 is also rotated.
Moves in the axial direction against the resilience of the coil spring 48, and at the same time, the uneven portion 47b is disengaged from the uneven portion 41 of the bearing portion 42, thereby giving a click feeling to the rotation operation to constitute the click mechanism K. ing.

[0009] In such a conventional click-type rotary electric component, in response to various operating forces and various click forces, for example, the first to third operating forces and the first to third operating forces are used. In order to respond to the click force, the first to third
A total of six parts are prepared, including three coil springs 48 having individual operating forces and three click members 47 serving as first to third click forces having different sizes of the concave and convex portions 47b. What is necessary is just to prepare the latter rotary electric component with a click in comparison with the former rotary electric component with a click.

However, in the latter case, in order to obtain various click angles, the uneven portion 41 of the bearing portion 42 is required.
In addition, it is necessary to prepare both the concave and convex portions 47b of the click member 47 at different intervals. Therefore, in order to obtain various click angles, various types of the bearing portions 42 and the click members 47 are required. is there. In addition, since the click member 47 is spline-coupled to the non-circular hole 43a of the operation shaft 43, the spline coupling portion is located at the center of the rotary electric component D. There is a problem that the rotation area in which the click member 47 cannot be driven even if the 43 is rotated becomes large.

[0011]

That is, the rotary electric component with a click requires a large number of spring plates 38 in correspondence with various operating forces and various click forces. The rotary electric component has a problem that various types of bearings 42 and click members 47 are required to obtain various click angles.

Accordingly, an object of the present invention is to provide a click-type rotary electric component having a small number of components in correspondence with various operating forces, various click forces, and various click angles.

In addition, since the elastic force of the spring member 3 does not apply to the operation shaft 2 and presses the rotating body 9 against the housing 7, the rotation axis of the operation shaft 2 is inclined by the spring force of the spring member 3. And smooth rotation can be performed.

The driving member 4 is provided with a supporting portion 4c on the side where the holding portion 4d is formed, and the supporting portion 4c is held by the supporting member 1 in a cantilever state, and the projecting portion 4e side of the driving member 4 is supported. Since the movement is made in the axial direction with the portion 4c as a fulcrum, it is also possible to easily increase the movement of the driving body 4 on the side of the protrusion 4e, and it is easy to make a heavy click force, and to drive smoothly. The body 4 can be moved, and a smooth operation feeling can be maintained.

The supporting member 1 has a pair of holding portions 1f spaced from each other across a line Y perpendicular to the line in the axial direction W, and the holding portion 1f supports the supporting portion 4c.
Is held, the holding of the driving body 4 can be ensured, and the holding can be reduced in the radial direction, so that a small-sized one can be obtained. In addition, since the driving body 4 is formed of a synthetic resin molded product and the spring member 3 is formed of a metal plate, it is possible to provide a click mechanism capable of obtaining a smooth click feeling.
