  However, in the conventional rotary electric component described above, since the operation shaft and the push switch are arranged in the center, other components cannot be arranged in the central portion of the rotary electric component. When an LED or other electronic component is disposed, it must be disposed outside the rotating electrical component, and there is a problem in the illumination performance of the knob portion and the degree of freedom in mounting the electronic component.

  The present invention has been made in view of such problems, and can be rotated and pressed by the same operation shaft, and other components can be arranged at the center of the rotating electrical component. An object is to provide a rotating electrical component.

  A rotary electric component according to the present invention includes a housing having a hollow bearing portion, a hollow operation shaft rotatably held by the bearing portion, and a rotation that is housed in the housing and detects rotation of the operation shaft. A detection unit; and a push switch that is housed in the housing and driven by a pressing operation of the operation shaft in an axial direction. The operation shaft is rotatably held on an outer peripheral portion of the bearing portion. A housing portion is provided in an annular shape on the outer peripheral side of the bearing portion, and the rotation detecting means and the push switch are arranged in the annular housing portion.

  According to this configuration, since the rotation detecting means and the push switch are disposed in the annular storage portion provided on the outer peripheral side of the bearing portion of the housing, the inner peripheral side of the hollow bearing portion of the housing is free space. Therefore, for example, a light emitting diode for illumination and other electronic components can be arranged, and the degree of freedom of mounting the electronic components can be improved. In addition, since the rotation detecting means for detecting the rotation of the operation shaft and the push switch driven by the pressing operation in the axial direction of the operation shaft are provided, the rotation operation and the pressing operation can be received by the same operation shaft.

  In particular, in the rotating electrical component, it is preferable that the receiving member is constituted by a wall portion of the first case. In this case, since the receiving member is constituted by the wall portion of the first case, it is possible to reduce the number of parts and to restrict the movement of the pressing member with a simple structure.

  For example, in the rotary electrical component, the push switch is composed of a fixed contact provided in the second case and a movable contact plate made of a metal plate facing the fixed contact so as to be able to contact and separate. The urging member is preferably constituted by the movable contact plate. In this case, since the urging member can also serve as the movable contact plate of the push switch, the number of parts can be reduced and the assembling workability can be improved.

In this case, since a plurality of push switches are provided at intervals in the circumferential direction, any push switch can be driven even when the operation shaft is pushed in an inclined state. It is possible to improve the reliability of the mold electrical component. For example, by providing three or more push switches at intervals in the circumferential direction of the operation shaft, the push switch can be reliably driven while ensuring the balance of the pressing member.

  Further, in the rotating electrical component, the pressing member is provided with a pressing protrusion facing the movable contact plate and a restricting portion whose position is restricted, and the restricting portion causes the pressing member to be It is preferable that the pressing protrusions are arranged at positions corresponding to the plurality of push switches in a state where the pressing protrusions are positioned in the second case. In this case, since the pressing protrusion is provided on the position-controlled pressing member, for example, the central portion of the movable contact plate can be pressed by the pressing protrusion, and the end of the movable contact plate is pressed. The undesired deformation of the accompanying movable contact plate can be made difficult to occur, so that the life of the push switch can be extended. In addition, when the movable contact plate is reversed to cause a click feeling, a good click feeling can be obtained.

  In the rotary electric component, the biasing member is formed of a coil spring having a larger winding diameter than the bearing portion, and the coil spring is disposed between the pressing member and the bottom surface of the second case, The pressing member may be biased toward the first case by the coil spring. In this case, the operating shaft and push switch can be reliably restored, and the load at which the push switch is turned on can be easily changed, and can easily meet the specifications of various rotating electrical components. It becomes possible to do.

  In the rotating electrical component, the biasing member is formed of an elastic molded body made of rubber or elastomer having a deformable skirt, and the elastic molded body is formed on the bottom surface of the pressing member and the second case. The pressing member may be urged toward the first case by the elastic molded body. In this case, the operating shaft and push switch can be reliably restored, and the load at which the push switch is turned on can be easily changed, and can easily meet the specifications of various rotating electrical components. It becomes possible to do. Further, it is possible to easily obtain a good click feeling during the pressing operation by the reversing operation of the skirt portion of the elastic molded body.

  For example, in the rotary electric component, the rotation detecting means includes a conductive pattern provided in the first case and a slider that slides on the conductive pattern, and the slider is operated by the operation unit. The rotating body is provided with an annular rotating body housed in the first case that rotates together with the shaft and allows movement of the operating shaft in the axial direction. In this case, since the rotation detection means is configured by the conductive pattern and the slider that is in sliding contact with the conductive pattern, it is possible to reliably detect the rotation of the operation shaft with a simple configuration. In this case, since the push switch is provided in the second case, the pressing operation with respect to the operation shaft does not affect the rotation detection.

  Further, in the rotary electric component, a plurality of uneven portions are formed on a surface of the rotating body opposite to the surface on which the slider is provided, and a roller that engages and disengages the uneven portions is a leaf spring. You may make it hold | maintain and elastically urge to the said uneven | corrugated | grooved part side of the said rotary body.
