PROBLEM TO BE SOLVED: To provide a suction vehicle preventing air in a blower from leaking to the outside with a simple construction. SOLUTION: An air introduction duct 36 connected to a Roots blower 32 is extended upward and an inlet 36a is positioned above a cyclone dust collector 25 on a downstream side. The air introduction duct 36 is designed so that the maximum value (P<SB>max</SB>) of internal pressure in an air introduction opening 35 formed in a casing 33, duct pressure loss (ΔP) of the air introduction duct 36 when the internal pressure of the air suction opening has the maximum value (P<SB>max</SB>) and external pressure (p) of the air introduction duct 36 satisfy formula (1); P<SB>max</SB>-ΔP<p.
