On the other hand, if the protective member 27 is rigidly mounted on the vehicle body frame 5, even if the down frame 9 and the pivot frame 10 are separated from each other, the rigidity of the vehicle body frame 5 is secured by the protective member 27 connecting these together. The improvement is achieved. Thus, the additional function of the protective member 27 can be made different by selecting the site to which the protective member 27 is attached.

  As described above, in the motorcycle 1 according to the above-described embodiment, the second coupling portion 26 of the first coupling portion 25 and the second coupling portion 26 supporting the both ends of the protection member 27 is the protection member 27. Since the exhaust pipe support hanger 37 is a support portion of another different vehicle component (exhaust pipe 23), the necessity for separately providing a place and a structure for fixing the protective member 27 is reduced, and the protective member 27 can be used. It can be attached easily. Further, even when the down frame 9 and the pivot frame 10 are separated from each other, the space between them can be included in the protection area by the protection member 27, and the protection area can be expanded.

  Further, in the motorcycle 1 according to the above-described embodiment, the exhaust pipe support hanger 37 provided on the pivot frame 10 is used as the second coupling portion 26 for fixing the other end of the protection member 27. The protective member 27 can be supported on the pivot frame 10 without any processing.

  Further, in the motorcycle 1 according to the above-described embodiment, since the connecting member 39 for connecting the left and right main body portions 38 is disposed behind the lower extending portion 21 of the exhaust pipe 23, the forward space of the exhaust pipe 23 can be secured. In addition to suppressing the influence of the front wheel 2 on the movable range, the influence of the traveling air volume directly on the exhaust pipe 23 can be suppressed. Further, by bringing the connecting member 39 of the protective member 27 closer to the center of the vehicle body, it is possible to contribute to the concentration of the mass of the whole vehicle.

  Further, in the motorcycle 1 according to the above-described embodiment, the first region A1 of the protective member 27 is disposed in front of the engine 14, whereby the engine 14 can be protected from the front, and the second region of the protective member 27. By arranging A2 below the engine 14, the engine 14 can be protected from below.

  Further, in the motorcycle 1 in the above-described embodiment, the first area A1 of the protective member 27 is disposed so as to expand in the vehicle width direction, and the second area A2 of the protective member 27 is larger than the outermost end of step 28 Since the protection member 27 is disposed along the bank angle of the vehicle body of the motorcycle because it is disposed inside in the width direction, it is possible to achieve both of securing of the protection area by the protection member 27 and securing of the bank angle. .

  Further, in the motorcycle 1 according to the above-described embodiment, since the protective member 27 and the exhaust pipe 23 are fastened together to the exhaust pipe support hanger 37 by the fastening bolt 35 shared with each other, the number of parts involved in fixing both is reduced. And man-hours can be reduced.

  Further, in the motorcycle 1 according to the above-described embodiment, since the rear extension 22 of the exhaust pipe 23 is disposed on the inner side in the vehicle width direction than the protective member 27, the exhaust pipe 23 can be protected by the protective member 27. .

  Further, in the motorcycle 1 according to the above-described embodiment, since the protection member 27 is formed of the hollow cylindrical pipe member P, it is possible to achieve both of securing the strength and reducing the weight.
