At the same time, there will be such a negative pressure detecting device for throttling. Valve body mounting: When the vehicle is on the vehicle, the position of the connector with the terminal rib 1) of the sensor box, that is, the direction in which the connector is pulled out varies depending on the vehicle, and the right is the position of the rotation direction at intervals of 30 degrees. At the time of the selection, the degree of freedom of selection of the connector's lead-out direction is reduced, and it becomes difficult to adapt to the money vehicle. Here, the case of changing the interval of the apex recess of the positioning recess from 30 degrees to 15 degrees to form 24 apex recesses has been studied, so that the locking portion of the apex recess of the positioning recess is located (and The portion of the apex projection of the locating projection is shortened, and a sufficient locking force cannot be maintained with respect to the rotational force of the sensor box. That is, the portion where the apex recess is engaged with the apex projection is reduced. In addition, the locking portion of the apex recess can be enlarged as the diameter of the regular hexagon of the positioning recess is increased, but this causes an increase in the size of the sensor box and the pressing plate, which is not preferable. . Further, it is possible to arrange the direction in which the connector is led out at a desired position by manufacturing the throttle body and the pressing plate, but this causes an increase in the manufacturing cost, which is not preferable.
