Abstract
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.
Claims9
A work vehicle comprising:
- a top having a first hole;
- a plate having a second hole and attached to said top with said second hole in alignment with said first hole;
- an exhaust pipe having an internal path and a flange projecting outward and abutting against and thus attached to said plate;
- and
- a tail pipe having a portion positioned in said first and second holes, and an end in said internal path of said exhaust pipe,
- said plate being disposed between said top and said flange and serving as a reference in attaching said flange to said top,
- said first and second holes being larger than a diameter of said tail pipe in a radial direction of said tail pipe, there being a gap between said tail pipe and each of said first and second holes in the radial direction of said tail pipe.
A method for manufacturing a work vehicle, comprising the steps of:
- disposing a top having a first hole and a tail pipe to pass said tail pipe through said first hole;
- positioning a plate having a second hole on said top to have said second hole concentrically with said tail pipe;
- and
- attaching an exhaust pipe having an outwardly projecting flange to said top at said flange with reference to said plate positioned on said top,
- said first and second holes being larger than a diameter of said tail pipe in a radial direction of said tail pipe, there being a gap between said tail pipe and each of said first and second holes in the radial direction of said tail pipe.
