  The front cover 33 has a pair of hanging portions 33a, 33a extending downward on both sides so as to be disposed on both sides of the head pipe 12, and is formed in a substantially U shape that opens downward in front view. In other words, the lower end of the front cover 33, that is, the lower ends of both hanging portions 33 a and 33 a are arranged in front of and below the air cleaner 25. A pair of left and right direction indicators 40, 41 are disposed above both hanging parts 33a, 33a, and the direction indicators 40, 41 are provided at three locations spaced in the circumferential direction of the outer periphery thereof. The portions 40a, 40b, 40c; 41a, 41b, 41c are fastened to the front cover 33.

  Referring also to FIG. 6, a coupling portion 42 for coupling to the leg shield 35 is provided so as to extend vertically in the lower rear edge of the front cover 33, that is, the rear edge of both hanging portions 33a. The coupling portion 42 is coupled to the leg shield 35 in a state of being superimposed on the front portion of the leg shield 35. That is, the coupling portion 42 is disposed inside the overlapping plate portion 42a so as to form a groove portion 42c between the overlapping plate portion 42a continuous with the surface of the hanging portion 33a and the overlapping plate portion 42a. And a protrusion 42b protruding from the inner surface of the hanging portion 33a. The front portion of the leg shield 35 is fitted into the groove 42c so as to overlap the overlap plate portion 42a from the inside. The fitting projection 35a is projected. Thus, the surface of the overlapping plate portion 42 a is flush with the front surface of the leg shield 35 in a state where the overlapping plate portion 42 a and the fitting protrusion 35 a are overlapped.

  In order to fasten the coupling part 42 to the front part of the leg shield 35, a pair of bosses 43, 44 projecting toward the leg shield 35 are vertically spaced on the inner surface of the hanging part 33 a in the vicinity of the coupling part 42. The mounting portions 45, 46 corresponding to the bosses 43, 44 are integrally provided on the upper part of the leg shield 35. Thus, the bolts 47 and 48 are inserted from the leg shield 35 side into the bosses 43 and 44 and the mounting portions 45 and 46 that correspond to each other, and nuts (not shown) that are held non-rotatably by the bosses 43 and 44. ) And the bolts 47 and 48 are screwed and tightened to fasten the coupling portion 42 to the front portion of the leg shield 35.

  Further, the left and right sides of the front cover 33 above the hanging portion 33a are fastened to the main frame top cover 36 with the same structure as the fastening structure of the coupling portions 42 to the leg shield 35. A pair of mounting portions 51 and 52 through which bolts 49 and 50 for fastening the left and right sides of the front cover 33 are inserted are provided on both sides of the top cover 36, and the mounting portions 51 are provided on the inner surfaces of the left and right sides of the front cover 33. , 52 are individually provided in pairs.

  An engaging portion 57 that is detachably engaged with a locking member 56 provided on the vehicle body frame F side is integrally provided inside the front cover 33, and the engaging portion 57 is provided on the left and right sides of the front cover 33. Is integrally projected on the inner side of the front cover 33 at the center between the direction indicators 40 and 41 provided in the front.

  On the other hand, as shown in FIG. 2, the locking member 56 is provided in a battery case 60 that houses and holds a battery 59. The battery case 60 has lower attachment portions 60a provided on the left and right sides of the battery case 60. In addition, it is attached to the head pipe 12 by fastening an upper attachment portion 60b provided on the upper portion. The engaging portion 57 is engaged with the locking member 56 through a grommet 58 that is an elastic member. That is, when the engaging portion 57 is inserted into the grommet 58 held by the locking member 56, the engaging portion 57 is engaged with the locking member 56 via the grommet 58.

  A grid-like rib 61 for increasing the rigidity of the front cover 33 is integrally provided on the inner surface of the center portion of the front cover 33 below the engaging portion 57.

  1, the pair of rear side covers 37 are coupled to the rear body cover 38, and the rear side covers 37 and the rear body cover 38 are attached to the rear portion of the vehicle body frame F in a small assembled state. The rear side covers 37 and the rear body cover 38 can be easily assembled to the vehicle body frame F.

  In addition, the surface of the rear body cover 38 is painted as shown in FIG. 1 with a fine lattice pattern, whereas the two rear side covers 37 are made of a colored resin on the surface. Even if the driver's foot hits the surface of the rear side cover 37 that is easy for the driver's foot to sit on the riding seat 29 to be damaged, the pattern is formed. Scratches can be made inconspicuous.

  That is, it is possible to reduce the cost by omitting the coating, and to make the surface of the rear side covers 37 inconspicuous, and the rear side covers 37 and the rear body cover 38 have a two-tone color, A design effect that modernizes the parting lines of the cover 37... And the rear body cover 38 can also be obtained.

  Next, the operation of this embodiment will be described. The coupling portions 42 formed at the lower rear edge of the front cover 33 are fastened while being overlapped with the front portions of the leg shields 35, and the vehicle body frame is placed inside the front cover 33. An engaging portion 57 is provided that is detachably engaged with a locking member 56 provided on the F side. That is, the front cover 33 is not only fastened to the leg shields 35 by the coupling portions 42 formed on the lower rear edge thereof, but also the engaging portions 57 provided on the front cover 33 are locked on the vehicle body frame F side. Since the member 56 is detachably engaged with the member 56, the front cover 33 is not necessary for the operator to hold the front cover 33 only by engaging the engaging portion 57 with the locking member 56. It is possible to perform fastening and unfastening operations of the connecting portions 42 to the leg shields 35, and it is possible to easily perform the attachment and removal of the front cover 33 while reducing the number of work steps.

  Further, direction indicators 40 and 41 are provided on the left and right sides of the front cover 33, and an engaging portion 57 is provided on the inner side of the front cover 33 at the center between the direction indicators 40 and 41. Since the portion 57 is engaged with the locking member 56 via the grommet 58, the front cover 33 is elastically supported on the vehicle body frame F side at the center between the left and right direction supporters 40 and 41. 33 can be obtained, and in particular, the vibrations of the bidirectional indicators 40 and 41 can be effectively suppressed.

  Further, since the locking member 56 is provided in the battery case 60 attached to the head pipe 12 of the vehicle body frame F, it is unnecessary to attach a dedicated member other than the battery case 60 to the vehicle body frame F side, and the number of parts is reduced. Reduction can be achieved.

  An air cleaner 25 that constitutes a part of the intake system 26 of the engine E mounted on the vehicle body frame F is disposed above the cylinder head 23 of the engine E, and the lower end of the front cover 33 is located at the front lower side of the air cleaner 25. Since it is arranged, the waterproof effect of the air cleaner 25 can be obtained by arranging the lower part of the front cover 33 in front of the air cleaner 25.

  Further, since the coupling portions 42 of the front cover 33 are formed to extend in the vertical direction, the coupling portions 42 of the front cover 33 are made relatively long in the vertical direction, and the rigidity of the fastening portions of the front cover 33 and the leg shield 35. Improvements can be made.

  Although the embodiments of the present invention have been described above, the present invention is not limited to the above-described embodiments, and various design changes can be made without departing from the present invention described in the claims. It is.

  For example, in the above embodiment, the case where the front side covers 34, the leg shields 35, and the main frame top cover 36 are integrally formed has been described. However, the front cover is connected to the front portions of the left and right leg shields which are separate members. The present invention can also be applied to a motorcycle.
