A recessed portion 145 is formed.

The operational effects of the saddle riding type vehicle described above will be described next.
As shown in FIGS. 7 to 8, an auxiliary machine arrangement tray 62 made of a plate-like resin molded product having a plurality of surfaces is attached to the vehicle body frame 21. Since the auxiliary machine parts 153 and 154 are attached to the auxiliary machine arrangement tray 62 at a time, the number of dedicated members required for attaching the auxiliary machine parts 153 and 154 can be reduced. In addition, since the auxiliary equipment arrangement tray 62 supports the wiring and piping, the number of dedicated support members necessary for supporting the wiring and piping can be reduced. Since the number of attachment members and support members is reduced, the number of parts is reduced. Since the number of parts is reduced, the number of assembling steps can be reduced. Since the number of parts is reduced, the weight of the vehicle can be reduced.

  As shown in FIG. 4, a canister 70 is arranged between the storage box 61 and the sub cover 62 in front of the rear fender 38. That is, the canister 70 is disposed in a region surrounded by the storage box 61, the sub cover 62, and the rear fender 38. The rear fender 38 is disposed behind the canister 70, the storage box 61 is disposed above the canister 70, and the sub cover 62 is disposed below the canister 70. Therefore, the canister 70 can be disposed in a highly dustproof space. it can.

  As shown in FIG. 11, the canister 70 is arranged so that the left end surface 139 is on the upper side and the right end surface 140 is on the lower side. By arranging the canister 70 obliquely rather than horizontally, the dimensions in the vehicle width direction can be shortened.

  A rib wall 128 extends from the auxiliary equipment arrangement tray 62 so as to surround the atmosphere opening 131 provided in the canister 70 attached to the auxiliary equipment arrangement tray 62. With such a configuration, since the rib wall 128 exhibits a blocking action, it is difficult for foreign matters such as dust to enter the atmosphere opening 131 of the canister 70 from the outside.

  Conventionally, in order to prevent intrusion of foreign matter, a hose is connected to the air opening and the tip of the hose is disposed in a clean space. However, the weight increases by the amount of the hose, and the procurement cost of the hose increases. In this regard, according to the present invention, a hose extending to a clean space is not necessary. Further, if only the dustproof viewpoint is considered, in this embodiment, the drain pipe 142 can be eliminated. As a result, weight reduction and cost reduction can be achieved.

  A wall portion 86 is extended outward from the storage box 61, and a rib wall 128 is extended from the auxiliary equipment arrangement tray (sub cover) 62 along the wall portion 86, and the rib wall 128, the wall portion 86, The labyrinth part 89 was formed.

  With this configuration, the outside air reaches the atmosphere opening port 131 through the labyrinth portion 89, so that intrusion of foreign matters such as dust and dirt from the atmosphere opening port 131 can be prevented. By disposing the atmospheric opening 131 of the canister 70 in a more dustproof space (labyrinth chamber 128), the hose connected to the atmospheric opening 131 can be eliminated. As a result, weight reduction and cost reduction can be achieved.

  The cylindrical portion 130 of the canister 70 is disposed obliquely so that the atmosphere opening 131 is positioned below. Since the atmosphere opening port 131 is arranged in the lower part of the labyrinth chamber 128, even if the outside air contains dust / dust, intrusion into the atmosphere opening port 131 can be suppressed. As a result, the dustproof property of the canister 70 can be further enhanced.

  The canister 70 is attached to an auxiliary equipment arrangement tray (sub cover) 62. Rather than using a dedicated stay that supports the canister 70 on the vehicle body side, an increase in the number of parts can be suppressed by supporting the canister 70 with the auxiliary device arrangement tray (sub cover) 62 as in the present invention.

  As shown in FIGS. 8 to 9, if the auxiliary machine arrangement tray 62 is formed into a plate shape, even if the vehicle has different specifications of auxiliary machines, wiring and piping, the change on the vehicle body frame 21 side depending on the vehicle type is small. It is possible to cope with the problem by changing only the shape of the auxiliary machine arrangement tray 62. Therefore, it is easy to produce on the same line even for different vehicle types. If different models can be produced on the same line, assembly productivity can be increased.

  Alternatively, the canister 70 and the purge pipe 66 extending from the canister 70 may be assembled in advance to the auxiliary equipment arrangement tray (sub cover) 62 to form a subassembly, and this subassembly may be assembled to the vehicle body side. As described above, by performing sub-assembly in advance, it is possible to improve productivity related to assembly.
