  • the air cleaner 100 is attached to the base 26 at its mounting portion 140 so that the engine side in the vehicle width direction can displace in response to external forces from the engine. Therefore, the mounting portion 140 of the air cleaner 100 on the base 26 can absorb external forces associated with engine roll and the like that are transmitted to the air cleaner 100 through the connecting duct 136.
  • the case 110 is inclined toward the rear in the vehicle's fore-and-aft direction toward the top of the vehicle, and the filter 116 is disposed inside the case 110 with the rear side in the vehicle's fore-and-aft direction inclined downward (see FIG. 3). Therefore, the direction of the air flow sucked in from the front side in the vehicle's fore-and-aft direction through the intake duct 130 is gently changed and passed through the filter 116. This reduces the loss of air pressure in the air cleaner 100.
  • a large space S1 can be secured between the air cleaner 100 and the master cylinder 16 arranged at the rear of the lower part of the air cleaner 100 in the vehicle longitudinal direction. This makes it possible to more effectively prevent contact between the air cleaner 100 and the master cylinder 16 arranged at the rear side of the air cleaner 100 in the vehicle longitudinal direction.
  • a large space S2 can be secured above the air cleaner 100 and the battery 200.
  • the fastening portion 148 of the air cleaner 100 is positioned so that it overlaps with the space S2 between the air cleaner 100 and the battery 200 when viewed from the top-bottom direction of the vehicle, so that the fastening portion 148 of the air cleaner 100 can be easily fastened to the base 26 by passing a tool through the space S2 and using the bolt 154.
  • the case 110 of the air cleaner 100 is inclined rearward in the vehicle front-rear direction toward the top of the vehicle, when an external force caused by engine roll is transmitted to the air cleaner 100 through the connecting duct 136, the external force can be applied evenly to the upper part of the case 110. This makes it possible to prevent the opening at the joint between the lower case 112 and the upper case 114.
