<p>PURPOSE:To enable each of the first body being provided with an airflow sensor and the second body being provided with a throttle valve to be connected on the same axis, by providing projected parts and recessed parts for positioning on the contacting surfaces of both bodies. CONSTITUTION:A body 7 contains a hot-wire type airflow sensor 3 in the vicinity of a bypass passage 2. A body 8 has an intake passage through which the intake air from the body 7 is introduced to the side of an internal combustion engine, and in this intake passage a throttle valve 9 is arranged. On the contacting surface of the body 7 pins are press-fitted, and on the contacting surface of the body 8 circular holes and oval holes are bored. Thus, respective bodies can be connected nearly on the same axis, and further the enhancement in the accuracy of detecting output of the airflow sensor can be achieved.</p> |
