Problems solved by technology

[0004] However, in the conventional rotary electric components as described above, if they are exposed to high temperature in a reflow soldering process, etc., local thermal deformation of the rotary component due to the biasing force of the leaf spring may occur.
In this case, there is a problem that unevenness occurs in the torque due to the difference in the rotational position of the rotating shaft, and operability is impaired.

Abstract

The invention provides a rotating electric component that prevents disproportion of a torquemoment with favorable operability, wherein the rotating electric component characterized in that the invention comprises the following components: a bearing component (1) provided with a through hole (101) that made of metal; a rotational axis (2) that can insert into the through hole (101) rotatablely; a sliding part bearing part (4) that can hold a sliding part (3) and rotates with the rotational axis (2); an insulation component (6) provided with conductive pattern (501) that connected with the sliding part (3) in a sliding way; a plate spring (7) that exerts load to rotation of the rotational axis (2). In the rotating electric component, the plate spring (7) is mounted on the sliding part bearing part (4) and a spring connection part locally set on the plate spring (7) connects with interior surface of the sliding part bearing part (4).

Description

technical field [0001] The present invention relates to a rotary electric component, and particularly to a rotary electric component used for various controls of electronic equipment and the like. Background technique [0002] Conventionally, there is known a rotary electric component that obtains the torque of the rotary shaft by pressing a leaf spring against the rotary member that rotates together with the rotary shaft for the rotary operation (for example, refer to Patent Document 1). In this rotary electric component, a leaf spring made of a metal material is pressed against a rotating member made of synthetic resin, thereby obtaining a torque of the rotating shaft. [0003] [Patent Document 1] Japanese Patent Laid-Open No. 2006-260826 [0004] However, in the conventional rotary electric component as described above, when exposed to high temperature in a reflow soldering process or the like, local thermal deformation of the rotary component to which the biasing force ...
