Since the front surface and the engagement surface 98 of the support plate 101 are orthogonal to the movable direction of the intake duct 58 with respect to the water blocking member 89, the detachment of the claw piece 96b from the engagement hole 99 is in accordance with the engagement of the support plate 101 and the engagement surface 98.

Thus, the claw 96b can enter the lock hole 99. Therefore, when the claw pieces 96b come close to each other according to the action of the external force, the contact surface 98 of the claw piece 96b can be separated from the support plate 101, and the claw piece 96b can be separated from the engagement hole 99.

Since the traveling wind that enters from the intake port 81 and travels toward the opening end 58a of the intake duct 58 is blocked by the water blocking wall 89a, water contained in the traveling wind (for example, rain water or water jumping from the road surface) is blocked by the water blocking wall 89a.

Then, it flows from the turnaround passage 93 into the space 92 in contact with the back side of the water blocking wall 89a. Water contained in the traveling wind adheres to the rear wall 86 of the shroud 82 along the water blocking wall 89a and the upper plate 89b in accordance with the inertial force of the traveling wind. Water is thus separated from the traveling wind. Air flows into the open end 58 a of the air intake duct 58 while preventing water from entering.

Abstract

L'invention concerne un véhicule de type à selle (11) comprenant : un moteur (28) suspendu à un châssis de véhicule (12) ; un radiateur (55) disposé devant le moteur (28) pour refroidir l'eau de refroidissement du moteur (28) ; un épurateur d'air (57) disposé au-dessus du moteur (28) ; et un conduit d'admission (58) s'étendant vers l'avant à partir d'une paroi inférieure de l'épurateur d'air (57) et ouvert au-dessus du moteur (28) et du radiateur (55). Le conduit d'admission est ainsi ouvert vers l'avant du véhicule et permet de réduire la perte de pression.
