发明名称 Work vehicle and method for manufacturing the same
摘要 A work vehicle includes: a top having a first hole; a plate having a second hole and attached to the top with the second hole in alignment with the first hole; an exhaust pipe having an internal path and a flange projecting outward and abutting against and thus attached to the plate; and a tail pipe having a portion positioned in the first and second holes, and an end in the internal path of the exhaust pipe. The plate is disposed between the top and the flange and serves as a reference in attaching the flange to the top. Thus, a work vehicle that can facilitate disposing an exhaust pipe and a tail pipe concentrically and provide better workability in disposing the exhaust pipe and the tail pipe concentrically, and a method for manufacturing the work vehicle, can be provided.
