To secure a sufficient space from an intake system component around a throttle body without increasing the size of a vehicle even when a canister is arranged behind an engine.SOLUTION: An evaporated fuel treatment device has an air cleaner arranged behind an engine (30) so that air is guided from the air cleaner through an intake passage (89) to the engine and evaporated fuel from a fuel tank is introduced into the intake passage. In the evaporated fuel treatment device, there are provided a throttle body (41) provided with the intake passage, and a canister (51) for recovering the evaporated fuel from the fuel tank. On one side in the vehicle width direction of the throttle body, there is provided a driving motor (44). On an end face on the other side in the vehicle width direction of the canister, there are provided a surge nipple connected via a surge hose (61) to the fuel tank, and a purge nipple connected via a purge hose (62) to the intake passage.SELECTED DRAWING: Figure 3

    【課題】エンジン後方にキャニスタが配置された場合でも、車両が大型化することなく、スロットルボディ周辺の吸気系部品との隙間を十分に確保する。【解決手段】蒸発燃料処理装置は、エンジン(30)の後方にエアクリーナが配置され、エアクリーナから吸気通路(89)を通じてエンジンに空気が導かれ、燃料タンクの蒸発燃料を吸気通路に導入する。蒸発燃料処理装置には、吸気通路が形成されたスロットルボディ(41)と、燃料タンクの蒸発燃料を回収するキャニスタ(51)と、が設けられている。スロットルボディの車幅方向の一方側に駆動モータ(44)が設けられている。キャニスタの車幅方向の他方側の端面には、サージホース(61)を介して燃料タンクに接続されるサージニップルと、パージホース(62)を介して吸気通路に接続されるパージニップルと、が設けられている。【選択図】図3
