  The present invention relates to an electronic device attachment method for attaching an electronic device related to measurement or transmission of a state of a pneumatic tire to a rim wheel provided with a drop portion.

  Conventionally, a housing that houses an electronic device such as a sensor that measures the air pressure (internal pressure) of compressed air filled in a pneumatic tire, a transmitter that transmits information output from the sensor, and the like, and There is known an electronic device integrated valve in which an air valve for filling a pneumatic tire with compressed air is integrated (for example, Patent Document 1).

  By mounting the electronic device integrated valve on the rim wheel, the housing for housing the electronic device described above is disposed outside the rim wheel in the radial direction of the wheel (that is, the space defined by the pneumatic tire and the rim wheel). It is possible to measure the air pressure (internal pressure) of the compressed air filled in the pneumatic tire.

  Here, in general, a drop portion that is recessed inward in the wheel radial direction is provided at the approximate center in the wheel width direction in the cross section in the wheel width direction. That is, the drop portion of the rim wheel has a drop parallel surface that is substantially parallel to the wheel width direction in a cross section in the wheel width direction, and a drop that is inclined outward from the both ends of the drop parallel surface in the wheel radial direction. It is composed of slopes. A rim side valve insertion hole through which an air valve constituting an electronic device integrated valve is inserted is provided on one drop slope constituting the drop portion.

  By the way, the housing (electronic device) constituting the electronic device integrated valve is disposed on the drop parallel surface constituting the drop portion of the rim wheel. In addition, an air valve is fixed to the side surface of the housing constituting the electronic device integrated valve at an angle inclined inward in the radial direction of the rim wheel in order to insert the air valve into the rim side valve insertion hole.

That is, when the electronic device integrated valve is attached to the rim wheel, the casing that constitutes the electronic device integrated valve is disposed on the drop parallel surface, and the air valve that constitutes the electronic device integrated valve is removed from the side surface of the casing. The wheel is inclined inward in the wheel radial direction and is inserted through the rim side valve insertion hole.
