Abstract

PURPOSE:To ensure return turning of a rotor to enhance durability by providing a connection lever with an engaging protrusion engageable by closing direction turning of a throttle body lever and an engaging surface engageable by opening direction turning thereof. CONSTITUTION:The throttle valve sensor 1 is fitted in such a manner that a fitting part 23 thereof fits with a fitting part 43 of a throttle valve body 40, and a throttle lever 45 in a closed position is interlockingly connected to a connection lever 15. When the lever 45 is turned in the opening direction, a pressing surface of an engaging part 46 is brought into surface contact with an engaging surface of the lever 15 to push it out, and the lever 15 is turned, while winding a return spring 30, in the open direction to turn a rotor 10. When the lever 45 is turned in the opening direction in this state, the lever 15 is turned in the opening direction by energizing force of the spring 30 to turn the rotor 10 in the returning direction. When turning resistance of the rotor 10 exceeds the energizing force of the spring 30, the engaging part 46 turns by a gap quantity, a return surface thereof abuts on an engaging protrusion 16 to push it out, and the lever 45 compensates energizing force to turn the lever 15 in the opening direction.

However, in the throttle valve opening sensor having such a conventional structure, the rotor shaft and the bearing are abraded by the rotational friction between the rotor shaft and the bearing, and the abrasion powder is generated. It entered the bearing clearance and increased the rotation resistance of the rotor shaft. As a result, even if the throttle body lever rotates in the closing direction, the rotor does not follow smoothly with only the rotational biasing force of the return spring, which makes it impossible to detect the accurate opening of the throttle valve.

1. A substrate having an opening detecting portion of a throttle valve, a rotor having a rotor shaft and having sliding contacts sliding on the opening detecting portion, and fixed to the rotor shaft. A connecting lever that is provided so as to be connectable to an engaging portion of a throttle body lever that interlocks with opening and closing of the throttle valve; a housing that includes a bearing that accommodates the substrate and rotatably supports the rotor shaft; A throttle valve opening sensor including a return spring interposed between a connecting lever and a housing for biasing the connecting lever to rotate in the closing direction of the throttle body lever, wherein the connecting lever comprises: An engaging protrusion that can be engaged with one surface of the engaging portion by rotating the throttle body lever in the closing direction, and the engaging protrusion that can be rotated by rotating the throttle body lever in the opening direction. Throttle valve opening sensor and characterized in that it comprises a passive portion having an engageable engaging surface on the other surface of the engagement portion.
