In addition, according to the inlet duct of the present embodiment, connecting piece 25 has the pipe portion 26 of bending, and above-mentioned pipe portion 26 links convex
Edge 27 and flange part 28 are equipped with inhaled air volume detection sensor 31, above-mentioned inhaled air volume detection sensing in pipe portion 26
Device 31 detects the state for the sucking air for flowing through air inlet pipe 14.
Moreover, inhaled air volume detection sensor 31 is arranged between imaginary line L1 and the outer wall 26c of pipe portion 26, above-mentioned vacation
Think the circumscribed circle P1 of line L1 attachment flange portion 27 and the circumscribed circle P2 of flange part 28 and the outer wall 26c along pipe portion 26.
Thus, it is possible to by inhaled air volume detection sensor 31 be arranged adjacent to flange part 27,28 circumscribed circle P1, P2 it
Between the high pipe portion 26 of rigidity.Therefore, it is possible to inhibit inhaled air volume detection sensor 31 to generate vibration, sucking can be prevented empty
The accuracy of detection of tolerance declines.
In addition, according to the inlet duct of the present embodiment, throttle body 19 has：Throttle body main body 20 has installation
In the flange part 20B of flange part 28；Motor 21 is installed on throttle body main body 20；And driving portion 22, it is installed on section
The driving force of motor 21 is transmitted to air throttle 20A by valve phosphor bodies 20, and motor 21 is contacted with flange part 20B.
Thus, it is possible to which motor 21 to be arranged adjacent to flange part 20B and the connection of the high throttle body main body 20 of rigidity
The flange part 28 of pipe 25 can inhibit motor 21 to generate vibration.Thus, it is possible to prevent air throttle 20A from generating vibration, Neng Gouwen
Surely inhaled air volume is adjusted.In addition it is also possible to instead of motor 21 is not contacted with flange part 20B, driving portion 22 and flange
Portion 20B is contacted, and can also be that motor 21 and driving portion 22 are contacted with flange part 20B.
In addition, according to the inlet duct of the present embodiment, the outer wall of pipe portion 26 is provided with installation inhaled air volume detection and passes
The 2nd boss portion 26C, the 1st boss portion 26B and the 2nd boss portion 26C of 1st boss portion 26B of sensor 31 and installation conduit 32 across
The central axis L of the extending direction of pipe portion 26 and mutually opposite.
Thus, it is possible to more effectively improve the rigidity of connecting piece 25, connecting piece 25 can more effectively be inhibited to generate vibration.
As a result, can more effectively inhibit throttle body 19, be vibrated as generations such as the air cleaners 15 of its circumferential component, energy
It is enough that throttle body 19 is arranged adjacent to front panel 8.
In addition it is also possible to install B/P EGR Back Pressure Transducer EGR in pipe portion 26 to replace inhaled air volume detection sensor 31.In addition, removing
Except B/P EGR Back Pressure Transducer EGR, other sensors can also be set, as long as the sucking air for flowing through air inlet pipe 14 can be detected
The sensor of state.
Although it is obvious that disclosing the embodiment of the present invention, those skilled in the art can not depart from the present invention's
It is changed in range.It is intended to all this modifications and equivalent include in detail in the claims.
