Abstract: A working vehicle includes a cabin. the cabin, which covers a steering seat disposed on a travelling machine body, includes a cabin frame constituting a framework of the cabin, and a roof assembly disposed on the upper end side of the cabin frame. A tailpipe is disposed on one side among a left side and a right side of the travelling machine body. Exhaust gas from an engine, mounted on the travelling machine body, is discharged to the outside through the tailpipe. The roof assembly is partitioned into a front-side chamber and a rear-side chamber, and an air conditioner is contained in a rear-side chamber side. An external-air intake opening is formed on one side opposite the tailpipe among a left side and a right side of the roof assembly.
