In this instance, a main air intake opening 19b opening toward the space A is formed at the top wall 19a. Meanwhile, an auxiliary air intake opening 19b is formed at the left side wall 19c of the air cleaner case 19. In addition, an outer air introduction opening 11a is formed, at a side cover 11 covering the lower portion of the seat 9, at a position which is displaced to the front further than an auxiliary air intake opening 19d. And outer air, after being introduced to the space A, is taken into the air cleaner case 19 through the main air intake opening 19b.
