However, a restriction projection is provided on the cylinder head 21 and the head cover 22 of the engine body 18. You may do it.

  Further, a stay 70 is fixed to the longitudinal intermediate portion of the front half inclined portion 15 a of the left seat rail 15 of the pair of seat rails 15, 15, and a third bolt fastened to the stay 70 with a fourth bolt 71. At the tip of the fuel hose support stay 72, a holder 73 is inserted for holding and inserting a portion of the fuel hose 53 that passes through the left side of the intake device 33 in plan view.

  By the way, the fuel hose 53 is connected to the fuel injection valve 51 from the rear side in order to secure a swinging amount of the fuel hose 53 accompanying the swinging of the engine body 18, that is, a vehicle frame F side fixing portion of the fuel hose 53, This is because it is necessary to ensure a large length between the support portion by the third fuel hose support stay 72 and the support portion by the engine E side fixing portion, that is, the first fuel hose support stay 56, and the fuel hose 53. Is connected to the fuel injection valve 51 from the front side, it becomes impossible to ensure a sufficient swinging amount of the fuel hose 53.

  Next, the operation of the first embodiment will be described. The intake pipe 35 having a mounting hole 54 for fitting a part of the fuel injection valve 51 and a fuel injection valve fastening boss 35c for fastening the fuel injection valve 51. Is connected to the cylinder head 21 so as to extend from the cylinder head 21 of the engine body 18 to the rear side in the vehicle longitudinal direction, and at least a part of the fuel hose 53 connected to the fuel injection valve 51 (this embodiment). Is partly routed so as to pass through the front side of the fuel injection valve 51 along the vehicle front-rear direction, and is supported by the first fuel hose support stay 56 attached to the intake pipe 35. However, the fuel injection valve fastening boss 35c is formed in the intake pipe 35 so as to be located on the left side in the vehicle width direction of the mounting hole 54, and the first fuel hose support stay is formed. 6 is formed in the intake pipe 35 so as to protrude from the fuel injection valve fastening boss 35c toward the front side along the vehicle front-rear direction. Therefore, the stay fastening boss 35d is connected to the fuel injection valve 51. When the fuel hose 53 is routed so that at least a part of the fuel hose 53 passes through the front side of the fuel injection valve 51 along the vehicle longitudinal direction, the first fuel hose support stay 56 is interfered with the fuel injection valve 51. The fuel hose 53 can be supported by extending from the fuel injection valve fastening boss 35c toward the front side along the vehicle front-rear direction while preventing the generation of the first fuel hose support stay 56. Can be achieved and the weight can be reduced. Moreover, the first fuel hose support stay 56 can be shortened by the amount that the stay fastening boss 35d protrudes from the fuel injection valve fastening boss 35c toward the front side along the vehicle longitudinal direction. It is possible to support the fuel hose 53 while ensuring the rigidity.

  Further, since the pair of fuel injection valve fastening holes 58 and 58 provided in the fuel injection valve fastening boss 35c and the axis of the stay fastening hole 60 provided in the stay fastening boss 35d are set in parallel, the fuel injection valve 51 The fastening operation to the fuel injection valve fastening boss 35c and the fastening work to the stay fastening boss 35d of the first fuel hose support stay 56 are facilitated, and the processing of the fuel injection valve fastening holes 58 and 58 and the stay fastening hole 60 is facilitated. It becomes easy and productivity improves.

Since the mounting boss 35e and the fuel injection valve fastening boss 35c are integrally formed, the rigidity of the stay fastening boss 35d can be increased using the fuel injection valve mounting boss 35e and the fuel injection valve fastening boss 35c. The degree of freedom in setting the protrusion amount of the stay fastening boss 35d can be increased.

  Further, the engine body 18 having the cylinder axis C tilted forward in the vehicle front-rear direction is supported by the vehicle body frame F so as to be swingable while being disposed below the storage box 43, and the stay fastening boss 35d is Since the first fuel hose support stay 56 is fastened to the stay fastening boss 35d, the portion supporting the fuel hose 53 is formed. It is possible to effectively prevent the storage box 43 from interfering with the storage box 43 even when the engine body 18 that is swingably supported by the vehicle body frame F swings. The capacity of the box 43 can be increased.

  The intake pipe 35 is connected to the cylinder head 21 so as to extend rearward from the cylinder head 21 along the vehicle longitudinal direction, and the fuel injection valve fastening boss 35c and the stay fastening boss 35d are Since the intake pipe 35 is disposed in front of the intake pipe fastening portion 35b for fastening the intake pipe 35 to the cylinder head 21 along the vehicle front-rear direction in plan view, the intake pipe fastening of the fuel injection valve fastening boss 35c and the stay fastening boss 35d is performed. While avoiding interference with the portion 35b, the workability of attaching / detaching the fuel injection valve 51 to / from the fuel injection valve fastening boss 35c, the workability of attaching / detaching the first fuel hose support stay 56 to / from the stay fastening boss 35d, and the cylinder head 21 Fastening workability can be improved by attaching and detaching the intake pipe 35.

  Further, since the fuel hose 53 is connected to the rear portion of the fuel injection valve 51 along the longitudinal direction of the vehicle via the connection connector 64, the connection portion of the fuel hose 53 to the fuel injection valve 51 and the fuel injection valve 51 The distance between the front portion of the fuel hose 56 and the support portion of the fuel hose 56 to the first fuel hose support stay 56 can be set relatively large, and the curved portion of the fuel hose 53 extends from the front to the rear of the fuel injection valve 51. It is possible to set a large radius of curvature of the fuel hose and effectively prevent the fuel hose 53 from being broken or crushed. In particular, since the fuel hose 53 is made of resin in this embodiment, the above effect is more remarkable.

  Also, the stay fastening boss 35d is engaged with the first fuel hose support stay 56 so as to restrict the movement of the first fuel hose support stay 56 around the axis of the stay fastening hole 60 provided in the stay fastening boss 35d. Since the engaging portion 63 for engaging the joining portion 62 is provided, the first fuel hose support stay 56 can be easily positioned and attached to the projectingly formed stay fastening boss 35d.

  Further, the fuel injection valve fastening boss 35 c is formed in the intake pipe 35 on the left side in the vehicle width direction of the attachment hole 54, and a coupler 68 for obtaining an electrical connection with the fuel injection valve 51 is provided in the attachment hole 54. A harness 69 that is provided on the right side in the vehicle width direction of the fuel injection valve 51 that is partially inserted into the vehicle and that is connected to the coupler 68 passes below the stay fastening boss 35d and is connected to the vehicle of the fuel injection valve 51.
