  However, in the conventional rotary electric parts as described above, since the light emitting element is attached to the rotating member using the holder, a process such as assembling the light emitting element into the rotating member is required. There is a problem that is bad. In addition, since a holder for holding the light emitting element is required, the number of parts increases, which makes it difficult to reduce the manufacturing cost.

  The present invention has been made in view of such problems, and an object of the present invention is to provide a rotating electrical component that is excellent in workability at the time of assembly and that can reduce the manufacturing cost.

The rotary electric component of the present invention can be inserted into a case having a cylindrical shaft serving as a bearing portion, an operation shaft having a hollow cylindrical portion rotatably held in the case, and a cylindrical portion of the operation shaft.

According to the rotating electrical component, the light emitting element is housed in the housing portion of the rotating member from the inner circumferential side of the rotating member, and the movement of the light emitting element is restricted on the outer circumferential surface of the cylindrical portion of the operation shaft. There is no need for a part corresponding to a holder for holding the light emitting element as in the prior art. For this reason, since the operation | work, such as incorporating a light emitting element in a holder, can be omitted, the workability | operativity at the time of an assembly can be improved. Further, since the parts corresponding to the holder can be omitted, the number of parts can be reduced, and the manufacturing cost can be reduced.

Can be done. Moreover, since the separated state of the pair of lead terminals included in the light emitting element can be maintained by the protruding piece formed in the housing portion without preparing a special member, the light emitting element can be easily handled. In addition, since the connection portion is formed by bending the tips of the pair of lead terminals included in the light emitting element into an L shape, a part of the conductive member is elastically contacted with the connection portion. In addition, since it is not necessary to insert into a predetermined through hole in order to fix the position of the pair of lead terminals, it is possible to further improve the workability when assembling.

In this case, since the elastic arm portion and the sliding contact piece protrude in different directions in the rotation axis direction of the rotating body, the conductive member is elastically contacted with the connection portion of the lead terminal with a simple configuration, and also for power supply. It is possible to make sliding contact with the pattern.

  Further, in the rotating electrical component, the attachment portions of the pair of conductive members are attached to positions facing each other across the pair of lead terminals, and the elastic arm portions are the pair of leads. It is preferable that the terminal is elastically contacted with the lead terminal disposed at a distant position. In this case, since the length of the arm portion in the elastic arm portion can be ensured, the reliability of connection with the lead terminal can be improved.

  Particularly, in the rotating electrical component, it is preferable that the pair of lead terminals are bent in a radial direction of the rotating body, and the elastic arm portion and the sliding contact piece extend in the same direction from each of the mounting portions. In this case, since the elastic arm portion and the sliding contact piece are provided in the same direction from the mounting portion, it is possible to improve the yield rate of the material at the time of manufacture and secure a wide rotation angle of the rotating body.

Thereby, for example, since it is not necessary to insert into a predetermined through-hole in order to fix the position of a pair of lead terminal conventionally, the workability | operativity at the time of an assembly can be improved. In addition, since a part of the first sliding member 6 is elastically contacted with the pair of lead terminals 5b, it is not necessary to make the first sliding member 6 in a complicated configuration. The manufacturing cost can be reduced.

  In the rotating electrical component according to the present embodiment, each of the pair of first sliding members 6 is attached to the rotating member 4 and extends from the attaching portion 6a to elastically contact the lead terminal 5b. The elastic arm portion 6b includes a sliding contact piece 6c that extends from the attachment portion 6a and is in sliding contact with the power feeding patterns 2a and 2b. Since it protrudes in the direction, it is possible to make the first sliding member 6 elastically contact with the tip portion 5e of the lead terminal 5b and to contact the power feeding patterns 2a and 2b with a simple configuration.

  In particular, in the rotary electrical component according to the present embodiment, the mounting portions 6a of the pair of first sliding members 6 are mounted at positions facing each other across the pair of lead terminals 5b (tip portions 5e). Thus, each elastic arm portion 6b is in elastic contact with the tip portion 5e of the lead terminal 5b disposed at a distant position of the pair of lead terminals 5b. Thereby, since the length of the arm part in the elastic arm part 6b is securable, it becomes possible to improve the reliability of connection with the lead terminal 5b.

  In the rotating electrical component according to the present embodiment, when the pair of lead terminals 5b are bent in the radial direction (outer peripheral side) of the rotating member 4 and the first sliding member 6 is viewed in plan view, The elastic arm portion 6b and the sliding contact piece 6c extend from the respective attachment portions 6a in the same direction. Thus, since the elastic arm portion 6b and the sliding contact piece 6c are provided in the same direction from the mounting portion 6a, the yield rate of the material at the time of manufacture is improved, and the operation shaft 3 and the rotation member 4 are rotated. A wide angle can be secured.
