  Further, as shown in FIG. 2, in the motorcycle according to the present embodiment, an ABS (Anti-Lock Brake System) is configured as a braking component in addition to the above-described disc brake 45 for front wheel and disc cake 48 for rear wheel. An ABS modulator 51 and a reservoir tank 52 are provided.

  The ABS modulator 51 is used to prevent the front wheel 23 and the rear wheel 28 from locking when sliding on the front wheel brake disk 45 and the rear wheel brake disk 48 to prevent the sliding of the road surface. The hydraulic pressure of the brake oil supplied to the brake caliper 46 and the brake caliper 49 of the rear wheel disc brake 48 is controlled so as to repeat depressurization, holding and pressurization. The reservoir tank 52 functions as a relief for brake oil when the ABS modulator 51 operates, that is, when the ABS modulator 51 reduces and holds the hydraulic pressure of the brake oil to the brake calipers 46 and 49. By the ABS, when the front wheel disc brake 45 and the rear wheel disc brake 48 are actuated, locking of the front wheel 23 and the rear wheel 28 is reliably avoided.

  Further, in the present embodiment, as shown in FIG. 1, the engine 30 (the cylinder head 31 and the cylinder 37), the throttle body 35, the suction pipe 36 and the air cleaner box 34 are sequentially arranged from the front of the vehicle in a side view of the vehicle. Further, as shown in FIGS. 1 and 2, at least a part of the suction pipe 36, the exhaust pipe 38, the ABS modulator 51, and the reservoir tank 52 are disposed so as to overlap with the rear cushion unit 29 in the upright state. It is done.

  Furthermore, in the present embodiment, as shown in FIG. 3, the suction pipe 36 and the exhaust pipe 38 are disposed on one side (for example, the left side) with the rear cushion unit 29 disposed in the upright state. And an ABS modulator 51 and a reservoir tank 52 are disposed. Thus, the ABS modulator 51 and the reservoir tank 52 are disposed at the rear of the engine 30 and at a position apart from the exhaust pipe 38 in the vehicle width direction with the rear cushion unit 29 separated.

  Further, the suction pipe 36 and the exhaust pipe 38 disposed on one side in the rear view of the vehicle (longitudinal sectional view including the rear cushion unit 29) have the suction pipe 36 upward and the exhaust pipe 38 downward. They are arranged side by side at substantially the same position. Further, the ABS modulator 51 and the reservoir tank 52 disposed on the other side in the rear view of the vehicle (the longitudinal view including the rear cushion unit 29) have the ABS modulator 51 upward and the reservoir tank 52 downward, and the vehicle vertical direction They are arranged side by side at substantially the same position.

Since it was comprised as mentioned above, according to this embodiment, there exist the following effects (1)-(3).
(1) As shown in FIG. 1, the rear cushion unit 29 is disposed at a position where at least a portion of the suction pipe 36 positioned behind the engine 30 in a side view of the vehicle overlaps. Furthermore, as shown in FIG. 2 and FIG. 3, the suction pipe 36 and the exhaust pipe 38 are on one side (left side) with the rear cushion unit 29 interposed in the vehicle rear view (longitudinal sectional view including the rear cushion unit 29). The ABS modulator 51 and the reservoir tank 52 are disposed on the other side (right side). As a result, the ABS modulator 51 and the reservoir tank 52, which are brake components, can suppress the heat damage received from the engine 30 and the exhaust pipe 38.

  Since the ABS modulator 51 has an electric substrate, heat from the engine 30 and the exhaust pipe 38 may cause heat damage such as easy detachment of the soldered portion. In the reservoir tank 52, the heat from the engine 30 and the exhaust pipe 38 causes the brake oil to expand excessively and can not sufficiently function as a relief, or the brake oil is exposed to high temperature and boils, Air bubbles may be generated in the oil to cause heat damage such as the generation of a vapor lock. In the present embodiment, the heat damage such as described above which the ABS modulator 51 and the reservoir tank 52 receive from the engine 30 and the exhaust pipe 38 can be reliably prevented.

  (2) As shown in FIG. 3, the suction pipe 36 and the exhaust pipe 38 disposed on one side (for example, the left side) in the rear view of the vehicle (longitudinal view including the rear cushion unit 29) are substantially the same in the vehicle vertical direction. The ABS modulator 51 and the reservoir tank 52 arranged side by side and arranged on the other side (for example, right side) are arranged side by side at substantially the same position in the vehicle vertical direction. As a result, the dimension in the vehicle width direction of the motorcycle 10 is suppressed, and the weight balance in the vehicle width direction is also improved, so that the steering stability of the motorcycle 10 can be improved.

  (3) As shown in FIGS. 1 and 2, the rear cushion unit 29 is disposed at a substantially central position in the longitudinal direction of the vehicle, in which a portion of the suction pipe 36 positioned behind the engine 30 in a vehicle side view overlaps . The ABS modulator 51 and the reservoir tank 52 are arranged such that a part of the rear cushion unit 29 overlaps the rear cushion unit 29 in a side view of the vehicle. That is, since the ABS modulator 51 and the reservoir tank 52 are disposed substantially at the center in the longitudinal direction of the vehicle, the ABS modulator 51 and the reservoir tank 52 do not separate from either the front wheel disc brake 45 or the rear wheel disc brake 48. As a result, it is possible to shorten the oil piping for flowing the brake oil.

  While the embodiments of the present invention have been described above, the embodiments are presented as examples and are not intended to limit the scope of the invention. This embodiment can be implemented in other various forms, and various omissions, replacements, changes can be made without departing from the scope of the invention, and those replacements or changes can be made. It is included in the scope and the gist of the invention, and is included in the invention described in the claims and the equivalent scope thereof.

  For example, the suction pipe 36 and the exhaust pipe 38 are disposed on the right side, and the ABS modulator 51 and the reservoir tank 52 are disposed on the left side, with the rear cushion unit 29 interposed therebetween in a vehicle rear view (longitudinal sectional view including the rear cushion unit 29) It may be done.
