  • the protective member 20 described above has an elongated shape that follows the longitudinal direction of the delivery pipe 18, and multiple first fixing portions 21 are provided in the longitudinal direction at the rear of the protective member 20. In this way, multiple points at the rear of the protective member 20 are fixed to the engine block, so that the protective member 20 itself does not lift up or fall over when subjected to a load during a vehicle collision (i.e., displacement of the protective member 20 can be suppressed), and the protective performance of the delivery pipe 18 can be improved.

Therefore, when the throttle body 15 and adapter 17 move backward during a vehicle collision, the adapter 17 comes into contact with the protective member 20, facilitating separation (breakage) of the adapter 17 and the throttle body 15 and making it easier to guide the throttle body 15 above the protective member 20. This further improves the protective performance of the delivery pipe 18.
  • a connecting bracket 30 is provided that connects the rear of the flange portion 17C of the adapter 17 to the eaves portion 25 of the protective member 20. This makes it possible to control and stabilize the breaking position of the adapter 17 and the throttle body 15 in the event of a vehicle collision to the front portion of these parts. This makes it easier to guide the throttle body above the protective member, further improving the protective performance of the delivery pipe.
  • the throttle body 15, protective member 20, and connecting bracket 30 are all made of metal and the adapter 17 is made of resin, even if the metallic throttle body 15 retreats during a vehicle collision, it is the adapter 17 that directly hits the protective member 20, and the throttle body 15 can be made to ride up onto the eaves portion 25 of the protective member 20 to avoid a direct collision. Furthermore, since the connecting bracket 30 that connects the adapter 17 and the protective member 20 is also a highly rigid part, the connected state between them can be maintained even during a vehicle collision, and the breaking position can be stabilized, thereby further improving the protective performance of the delivery pipe 18.
