Patent ID: 8887858

Claim:
An exhaust device for a work vehicle comprising: an exhaust pipe for guiding exhaust to a vehicle exterior, the exhaust pipe including: an exhaust guide pipe into which exhaust from an engine is introduced; an external protective pipe that externally fits onto the exhaust guide pipe and forms a passage for external air in a space bounded on one side by the exhaust pipe; and an ejector section for suctioning and introducing external air between an outer periphery of the exhaust guide pipe and an inner periphery of the external protective pipe by an ejector effect caused by exhaust discharged from the exhaust guide pipe, the ejector section being formed on a downstream-side end section of the exhaust pipe by positioning a downstream-side end section of the external protective pipe further downstream, with respect to an exhaust direction, than a downstream-side end section of the exhaust guide pipe; wherein: a curved-pipe portion curved so as to change the exhaust direction is connected to the downstream-side end section of each of the exhaust guide pipe and the external protective pipe, respectively, and spacing between an end-section outer periphery of the exhaust guide pipe and an end-section inner periphery of the external protective pipe in the curved-pipe portions is greater on a side opposite the center of curvature of the respective curved-pipe portions than the side nearer the center of curvature.
