Claims

[Scope of utility model registration request]

Throttle body, which forms part of the intake passage.
A valve shaft that passes through the intake passage and is supported by the throttle body, a throttle valve that is supported by the valve shaft and adjusts the amount of air flowing through the intake passage, and a drive shaft that has an end concentrically opposed to one end of the valve shaft. and a throttle valve opening detection sensor fixed to the throttle body to generate a detection output corresponding to the rotation angle of the shaft, and an engagement member for engaging opposing portions of the respective shafts. The mating member includes a first engaging piece having two grooves on one side of each shaft, and a U-shaped second engaging piece having two legs on the other side of each shaft that fit into the two grooves. The first engaging piece is formed by molding a metal plate integrally embedded therein, and a mounting hole is provided in the metal plate, and the mounting hole is fitted into the shaft end of the valve stem. 1. A throttle valve opening detection device for an engine, characterized in that:
